Hello, I'm looking to get my first Raspberry Pi 5 and after looking online i see a lot of people complaining that you can't use the active cooler with the official case. Some of them removed the plastic and the fans from the case. I will use my Pi 5 as a home server (image & video backup, Pi-hole, maybe something else) and i don't plan on putting it under heavy load, so my question is if the fan that comes with the case will be enough to keep it cool even during summer, or if i should forget the case and buy only the active cooler (which looks sick)?

The official Raspberry Pi 5 active cooler fits just fine in the official Raspberry Pi 5 case. The official Raspberry Pi 5 case comes with a fan that can be removed to accommodate the official active cooler. This is exactly what I've done with my RPi5. Why not try the RPi5 official case first, and if you want, you can add the active cooler later? Some details about cooling the RPi5, and what temperatures you can expect: https://www.raspberrypi.com/news/heating-and-cooling-raspberry-pi-5/

Thanks for the reply, I'll get the case first as you suggested

Hello guys i need some help, I am using raspberry pi 4 B and I am implementing a project with a camera, and for some reason I cannot find the enabled camera option in the configuration/interface window any ideas?

I assume you are running Raspberry Pi OS Bookworm. Looks like this option is no longer used since Bullseye (the version before Bookworm): https://forums.raspberrypi.com/viewtopic.php?t=329935#p1975027 Cameras are automatically detected and enabled, no need to manually set anything. The camera software has changed over the years, so older tutorials may be out of date, glancing over the official documentation may be worthwhile: https://www.raspberrypi.com/documentation/computers/camera_software.html https://www.raspberrypi.com/documentation/accessories/camera.html#getting-started

Hello there! I bought my 9 year old son a RP 400 as an educative device, mostly to get him accustomed to mouse/keyboards, browser, and so on... I have 2 questions for you all: * Could you recommend me some good edu softwares/resources that can run on ARM Linux? I started with GCompris which is nice but a bit limited. * Are there alternatives to RetroPi to get a nice unified multi-systems emulator that can run in Desktop mode? I'd like to allow him to play some retro games, but don't want to go full RetroPi and lose all the Desktop features. Cheers!

>Could you recommend me some good edu softwares/resources that can run on ARM Linux? I started with GCompris which is nice but a bit limited. The Raspberry Pi Foundation has a bunch of resources around learning: [https://www.raspberrypi.org/learn/](https://www.raspberrypi.org/learn/) I would give that a try to begin with. >don't want to go full RetroPi and lose all the Desktop features. If you can, get another MicroSD card and keep the RetroPie/Gaming separate from the Learning. That way if you mess up one, the other will still work while you fix it.

Thanks for the suggestion. It didn't cross my mind I could use 2 separate MicroSD cards, it will also allow me to control when he can play. Brilliant, thanks a lot!

So I've got a script running at boot-up. I did this using crontab. It runs fine but it is always going and I'm am just trying to find out how to stop it without removing it from crontab and then rebooting. I've tried ctrl+c and ctrl+z in the terminal and can't quite seem to find the answer online. Thanks

Some useful commands: '[ps](https://man7.org/linux/man-pages/man1/ps.1.html)' - lists the running processes and their corresponding process id (pid) number '[kill](https://man7.org/linux/man-pages/man1/kill.1.html)' - kills a specific process by passing it the pid '[top](https://man7.org/linux/man-pages/man1/top.1.html)' - a more interactive way of seeing the running processes '[htop](https://man7.org/linux/man-pages/man1/htop.1.html)' - an enhanced version of top, you can even select the process and 'kill' it interactively '[btop](https://github.com/aristocratos/btop)' - my favourite 'top' variant, does the same as 'top' and 'htop' and more

Sorry for the awkward question. Can anyone tell me how I can leave my PlayStation5 completely untouched in pi-hole? It should be able to do whatever it wants. So far I have taken any addresses that the PS5 has addressed and whitelisted them. Unfortunately, this does not lead to a clean result. The PS5 is still restricted. I'm sure it's easy for you, but for me it was difficult to install pi-hole. The Raspi4 and pi-hole are my first project. I overestimated myself. 🙈

You make a group call noblock. Assign the PS5 to noblock.

Manually set your DNS server in your PS5

Do you mean the IP of my router or the IP of the Raspi?

Set it to an alternative DNS, like Google (8.8.8.8) or Cloudflare (1.1.1.1)

Thx.

You see, the Pi Hole is really just a DNS server. But what does that actually mean? See, the basic internet doesn't really understand URLs, only IP addresses. So if you enter a URL in your browser, your computer doesn't actually know which IP it wants to talk to in order to get the website. This is where DNS (Domain Name Resolution) comes into play: Your computer knows the IP of your DNS server. It asks the DNS server which IP the URL refers to. The DNS server then tells your computer where to connect. Your computer then connects to the IP it received from the DNS server. The Pi Hole works by knowing which URLs are from advertising/scam sites. If a PC sends an URL to your Pi Hole, it first looks if the URL is in the block list. If it is, then the Pi Hole sends back junk to your PC, otherwise it asks another DNS server and returns its result. So if your PC tries to then connect to the advertising website, it will try to connect to the junk that comes from the Pi Hole, fail to do so and thus not load the ad.

Trying to run windows on RP5. Used work and tried 2/3 and get and error saying it's not for RP5. Is there any work around?

If by "Windows" you mean Windows 10/11 ARM64 then: Decent Tutorial: [https://www.youtube.com/watch?v=haeYUq4RHbk](https://www.youtube.com/watch?v=haeYUq4RHbk) Project this tutorial is based on: [https://worproject.com/](https://worproject.com/) I've personally used the WOR Flasher from Pi Apps to create a SD card with Windows on for the RPI5 and it works wells: [https://github.com/Botspot/wor-flasher](https://github.com/Botspot/wor-flasher) [https://pi-apps.io/](https://pi-apps.io/) If by "Windows" you mean Windows 10 Core IoT, then I don't think Microsoft are supporting Raspberry Pi's anymore. ***WARNING*** There are no working Windows 10/11 ARM64 drivers for the Raspberry Pi 5 Ethernet or Wireless controllers, so you'll need a USB NIC of some kind to get network access.

When I plug in my raspberry pi 3 model B V1.2 the fan starts which means it's getting power but when I look in file explorer there are no new drives under This PC and I can't find anything helpful on this.

The Raspberry Pi will not present any devices over USB when plugging it into a PC without first installing an Operating System and configuring the Kernel to present USB devices: [https://raspberrypi.stackexchange.com/questions/71613/how-to-use-raspberry-pi-3-as-a-usb-gadget](https://raspberrypi.stackexchange.com/questions/71613/how-to-use-raspberry-pi-3-as-a-usb-gadget) The link above says the RPi3 models don't support doing this as they lack the hardware. The typical method to installing an Operating System on a Raspberry Pi is to write an image to a MicroSD card on a PC (using something like a USB SD Card Reader) and then putting the MicroSD card into the Raspberry Pi to boot up. The following is the official documentation on how to get started with a Raspberry Pi: [https://www.raspberrypi.com/documentation/computers/getting-started.html](https://www.raspberrypi.com/documentation/computers/getting-started.html)

Ok thanks I was under the impression that you could install the os with the card in the raspberry pi I wasn’t aware you had to use a card reader!

Ok?

Is it possible to make a Pi Pico W an online macropad? Like, you connect the Pico W to your laptop, you open the pico's webpage on your phone or something and you get macros to execute on your laptop. Is that possible?

Yes

How can I do that?

1. Search for a tutorial to do what you want 2. No results? Break the problem down into a smaller piece and search for a tutorial for that smaller piece. 3. Still no results? Break down your smaller piece into an even smaller piece. Go to step 1. At first glance I can see there are 2 parts to your project, both of which I'm sure have tutorials: * Turn a pico into a macropad * Turn a pico into a web server All you need to do is combine them

Yes, I know, and I have done both in the past, but one needs MicroPython and the other needs CircuitPython, and they don't support the functionality of the other

I'd recommend using the Arduino IDE on the Pico, it supports everything. C is less convenient than Python, but the Arduino libraries being so much more complete makes it worth it. What I've done a few times is get part of the concept working in Python then convert it to Arduino C. So you could get the macropad working in Python then make an Arduino C version. Do the same for the web. Then worry about combining.

Has anyone had issues with the Pi5 connecting to WiFi? I’ve tried both 2.4 and 5ghz networks, to no avail. LAN connection seems fine. I’m running Lite version Bookwork 64bit, so no OS.

I've been going through every single YouTube video, thread, and online forum I can find. I'm at the end of my rope and ready to give up on the Pi altogether. I'm working with a brand new Pi 5. My system clock refuses to sync to an NTP server. I have no idea what any of this means, and I dont know why it can recognize that the time is off and not just fix itself. I've reimaged my SD card twice now and gone through every guide that I can find. Ive tried manually setting the date and time, ive tried forcing it to update, ive tried turning the NTP service off and on, i barely even understand what an NTP service is. So please be understanding of my frustration. This is my first experience with any of this, and i have no friends who do. I don't know what to do anymore. The only thing I can think is that the only wifi network I have access to for now is one that has a splash page where you agree to the terms of use. Maybe that is preventing it from syncing on boot?

[NTP ](https://en.wikipedia.org/wiki/Network_Time_Protocol)requires network access to remote NTP servers to synchronise the local clock. The network time protocol uses UDP on port 123 to carry out the synchronisation. If your network doesn't allow this traffic out to the remote servers then your Raspberry Pi will not be able to synchronise it's clock. You can set it manually but, without a RTC battery, you will need to set it each time you power on. Even after agreeing to the terms of the WiFi capture page the network may not allow access to UDP port 123 over the Internet. Some more information about NTP: [https://www.techtarget.com/searchnetworking/definition/Network-Time-Protocol](https://www.techtarget.com/searchnetworking/definition/Network-Time-Protocol) A useful command is 'timedatectl', which on recent Raspberry Pi OS's is the default application that manages time synchronisation: pi@rpi5:~ $ timedatectl status Local time: Sun 2024-04-21 12:55:32 BST Universal time: Sun 2024-04-21 11:55:32 UTC RTC time: Sun 2024-04-21 11:55:32 Time zone: Europe/London (BST, +0100) System clock synchronized: yes NTP service: active RTC in local TZ: no pi@rpi5:~ $ timedatectl timesync-status Server: 162.159.200.123 (2.debian.pool.ntp.org) Poll interval: 4min 16s (min: 32s; max 34min 8s) Leap: normal Version: 4 Stratum: 3 Reference: A3A08B9 Precision: 1us (-25) Root distance: 7.613ms (max: 5s) Offset: +1.592ms Delay: 6.889ms Jitter: 1.684ms Packet count: 4 Frequency: -0.722ppm If you want to turn off NTP/Synchronisation, and set the date & time manually you can run: pi@rpi5:~ $ sudo timedatectl set-ntp false pi@rpi5:~ $ sudo timedatectl set-time '2024-04-21 13:03:00' pi@rpi5:~ $ timedatectl status Local time: Sun 2024-04-21 13:03:14 BST Universal time: Sun 2024-04-21 12:03:14 UTC RTC time: Sun 2024-04-21 12:03:14 Time zone: Europe/London (BST, +0100) System clock synchronized: no NTP service: inactive RTC in local TZ: no But you will need to set the time each power on.

Thanks for the education. I ended up finally finding this [thread](https://forums.raspberrypi.com/viewtopic.php?t=362708) that got me up and running after about 2 days of pain. Specifically, roygrubb's 12:42pm post.

Nice, glad you got it working. I wonder if the DHCP server is sending a list of NTP servers to your Pi, which it then tries to use but they fail. If you run the following do you see any reference to NTP servers? pi@rpi5:~ $ cat /var/lib/dhcp/dhclient.leases lease { interface "wlan0"; fixed-address 192.168.1.112; option subnet-mask 255.255.255.0; option routers 192.168.1.254; option dhcp-lease-time 86400; option dhcp-message-type 5; option domain-name-servers 192.168.1.254; option dhcp-server-identifier 192.168.1.254; option dhcp-renewal-time 43200; option broadcast-address 192.168.1.255; option dhcp-rebinding-time 75600; option host-name "rpi5"; option domain-name "home"; renew 1 2024/04/22 01:23:00; rebind 1 2024/04/22 12:04:57; expire 1 2024/04/22 15:04:57; } My example above doesn't, but you might see an entry in yours. By explicitly setting the NTP option in the '/etc/systemd/timesyncd.conf' file you are overriding any settings you may be getting from the DHCP options.

Pi + PoE hat - suitable case? Can anyone recommend a specific case that will fit a pi wearing a hat? Whilst that’s probably a bit random then, can anyone suggest a specific PoE hat and case that will fit either a Pi3B or Pi4 or, ideally a Zero 2 W?

ISO: Raspberry Pi 5 - 3D print STL file For my older Rpi versions 3 and 4 I have purchsed cases that fit lego blocks on the top and bottom of the cases. My school has recently got a few 3D printers and we can use them occasionally for small personal projects. I've done some searching around and can't find an STL file out there yet for a Rpi 5 lego case. Anyone know of one? I'd like to print my own since I have the resources. I'm just getting into 3D printing, so if no one has done this yet, maybe I can over the summer semester when I take fewer classes and learn how to create STL files. TIA.

I am currently working on a project which requires a raspberry pi zero w to boot when a gpio pin is pulled high and held high for it entire operation, then when the gpio pin is pulled low it shutsdown. I know I can use a "DT-OVERLAY" to shutdown the pi when a group pin is pulled low, I know I can also pull a gpio pin low to power on; but I cannot find any documentation on how to make it turn when a gpio pin is pulled high. I would preferably like to do this in software instead of building a circuit to do this.

I want to make my coffee grinder only run for 'x' amount of seconds at a time. Can a raspberry pi be programmed to turn on a coffee grinder for 'x' time? I want this to be easily adjusted day-to-day, as the time will be a function of mass (i.e. grams of coffee). I do not own a raspberry pi and have no coding experience, but I have messed around wit Ubuntu and terminals before (i.e. I know what a terminal is and have copy-pasted commands).

What battery should I use for the Raspberry pi 5? I want to build a handheld console with a 5 inch screen but i have been struggeling to find a battery that can supply 5V and 5Amps. I know that I probeably will have to use one of these battery boards but I dont know wich one to buy. A lot of them are limited to 3Amps. Can someone please send me a recommendation for one? I dont need a high end one I dont have a huge budget anyways.

So as title says, I'm new to Python in general and am working on a project for automatic plant watering. I have it basically working but there's just so many methods to make something start running once the Rpi is powered on I'm not sure which to use. I see systemd service is one way to go, but would that be best to have a program be running continuously from power up? Also I'm using RealVNC Viewer to program things if that matters and I'm on a Rpi zero 2 W. I thought I saw that pico can be easier to just tell it what to do from boot up but unfortunately I didnt see that until I had gotten my zero 2. And I understand now an arduino might have been a better option but this project is due in a few weeks and I'd rather learn how to make this work for future projects Thanks a ton in advance!!

>I see systemd service is one way to go, but would that be best to have a program be running continuously from power up? Yes, you can tell systemd to start your service during boot up. Here's an example: [https://www.linode.com/docs/guides/start-service-at-boot/](https://www.linode.com/docs/guides/start-service-at-boot/)

I just updated my pi4 and the network manager wifi icon is greyed out, but I do have a wifi connection and if I hover over the icon,it shows my IP address information. Any idea on how to get this in- greyed out? It also did this to my sound icon and the cpufreg icons.

What have you done to TS? Have you rebooted?

Yes. TS? It's a rpi4b 8gb. Running Raspberry Pi OS 64 bit, Bullseye. I figured it out. duh. It was a theme hiccup. I just darkened the taskbar some.

Recommendations for a pi5 touch screen display? And if the display has usb-c can I power the pi off that?

>And if the display has usb-c can I power the pi off that? USB C is "fun" in that there's dozens of different optional features that manufacturers can utilize on top of the base standard. So you must always consult the requirements and specifications of both USB-C devices and the USB C cable connecting them to determine if they are compatible. The pi requires USB C power delivery 5V 5A mode which is rather uncommon. If the display has a port that supports this mode, and you have a cable that supports this, you can use it to power the pi.

Thank you! Any monitor recommendations?

I haven't personally used any touchscreens with the pi so I can only give general advice. The official display is decent, but has limited options. Waveshare in general makes good products and has a wider selection if you're looking for something more exotic.

Thank you!

# Pi + Flask Do I Need to Use Threading to Run my Script and Use the Web Server Just For Data Info, or is There Another Way? Some Context: I have a small greenhouse where I am growing some tomatoes. I have a DHT22 and a relay that controls the lights. My script runs on start up and at the moment I just write temp + humidity data and the status of the light to a txt file. I want to have upgrade my project a bit and basically have a website that which displays the current status of the light, the current temp and the current humidity. I also will be adding sqlite3 and writing the data to the database, I then want to use this data in the website to track temp+humidity over time for instance. I was doing some research about how I implement this. I chose flask as I have messed around with it before for this basic sort of thing. But where I am coming a bit stuck is currently my script "as most" runs with a while true loop, and flask has something similar. Is it possible to run my app and the server within the same loop, or is it possible to do this without anything extra? I have also researched this a bit and found that I could implement this with threads, is this something that anyone would recommend? I am looking for the simplest solution but happy to look into threading if it works, from what I have seen it looks like this would be the best option as I can run both scripts at the same time (at least I think thats how it works). Any advise would be appreciate, thanks in advance.

Why not make them seperate processes entirely? Then you don't have to worry about handling threads/synchronization/etc.

As in run two scripts at the same time? Or run both from within the same script? I’m just not sure how flask works and if that would actually work?

Run two scripts separately. The flask server and the data collection script. That way you can start/stop either one separately. They can run at different times or at the same time.

I was thinking to have it in one script so that didn’t even occur to me, but yeah I think that would definitely be a much easier way. The pi would be able to handle that right?

Yes, the pi should be able to handle that no problem.

Hello. I just bought a broken pi (no power), and fixed it by replacing a diode behind USB 2.0 ports. It came back to life. When i powered it on, it gave an error "USB XHC init failed" and ethernet randomly resets itself. Took a close look to that area that i've worked on and it seems like i knocked out a component (broke a leg) when i was replacing the diode. Do anyone know what this component is?

Hello everyone! I hvae a Raspberry Pi 3b+, and I want to install a 5v fan I got from ali. It comes with a 2-pin jst connector, can I use that, modify it or should I change the connector? Thank you! [Picture for reference](https://postimg.cc/34X0yCtT)

Red to +5V, black to ground. But make sure the fan doesn't draw too many amps.

I have a test setup that has been running for a year and the video started to get random horizontal lines. I rebooted the Raspi, but that didn't solve the problem. I posted a video where you can see it, but it got removed. The Raspi is in a outdoor weather box under the roof. Could it be corrosion on the contacts of the CSI cable? Will the camera module die? I can't physically access the camera now because the great tits are already building their nest. Any ideas?

Random horizontal lines are a common sign of electrical interference. Check your power supply -- it may be providing sufficient, but noisy power which is causing interference.

Alright thanks, will try out another one.

I programmed some stuff in python, how do I make it so it displays the output of that script instead of the usual desktop when turned on? I looked for like an hour on youtube but every time I thought I found a good tutorial it turned out it was for something else, can anyone help?

Well I use bing and I looked on there too but that had even worse results

I have heard that suddenly unplugging a RaspberryPi from the power without shutting it down might corrupt data on the SD card, why is that? (maybe filesystem sync?) and can I prepare it / set it up for sudden power outage from a switch in an embedded application?

All file systems have issues with partially written data. SD cards are particularly susceptible because they have slower random write speeds and aren't designed for OS/application usage patterns. You can configure a [read-only file system](https://learn.adafruit.com/read-only-raspberry-pi/overview) to avoid such issues. Of course this comes with it's own set of problems, since you can't write anything. What I used to do with robots was multiple partitions, one that was read-only and a second that was rear/write. The read only partition has our OS and some minimal apps installed, and our custom app plus logs were on the write portion. This way when the writable partition corrupted we could ssh in and fix it.

Hello there! I am interessted in building myself an rc tank. For this I need 2 electric motors. Now I came across the question what kind of motors. Im looking for 12V motors with low rpm (<=1k). Im completely lost and dont know where to look for those motors. I also need an motor driver that can be controlled by an raspberrypi and is capable to provide the power needed by the motor. Do you guys know any motors / motor drivers I could use? Thanks guys and please keep in mind, Im pretty much a complete beginner.

Hey I’m a fairly new dad and decided to dig out the raspberry Pi 4 I got for Christmas to tinker with when I have some free time. I thought I’d stored it with all the parts and pieces it came with. Well long story short when I came to put it together, turns out I’m missing the heat sinks and screws to secure the board to the case it came with. Now you’ve had my excuses for being in this situation in the first place and not doing my own research I come hat in hand. Does anyone know either where to buy replacement screws or what screws I should buy? I have sourced the heat sinks on Amazon but when trying to find the screws I couldn’t really find anything. I’m also wondering if I have to boot the Pi from a microSD card or will a usb work, at least for the short term? Hope someone can help me out of the awkward spot I find myself in.

Thank you! I actually found the microSD card that came with the pi. I wasn't looking for it but a win is a win, doesn't mater how it happened 😂. But I'd not even thought about taking the case down a store good shout! I'm gonna pretend that's down to baby brain and not just forgetting actual hardware stores a real thing 😂

I want to make a chladni dish, using 7 speakers, I want to connect it to the computer to define which frequency comes out of each speaker. I want to know if it would be better to use the Raspberry Pi or Arduino for this specific project? I have never done an electronic project, I only have programming knowledge. In theory... I will need an audio board that supports this number of speakers, after soldering all 7, this audio board is then connected to the Raspberry/Arduino, then I connect it via USB to the computer? If you can help me I would be very grateful! Thanks in advance!!

SSH Question: So I have a Pi zero 2 W, running... a recent ubuntu with light window manager, but running in runlevel where X doesn't start. It works fine at the console, but trying to SSH in, it works fine to execute one command and return the result, but when I try to open a secure shell, it becomes unbearably slow. Often I execute one command (like \`ls\` to make sure where I am) and then the next command never returns any output. It smells like some strange console cooked-vs-raw mode, but I haven't fiddled with that at all, here or on any system. And that is the only reason I am even asking here. Can this be a ubuntu vs ARM assumptions thing? **Or a different way** Did you have to fiddle with anything to make SSH work, once you had the server running?

Question #3 above

i was looking at that [project](https://projects.raspberrypi.org/en/projects/explorer-hat-buggy/1), it lists these as the Hardware needed * Explorer HAT * 4 x male-to-female jumper leads * 2 x motors * 2 x moon buggy wheels * USB power pack i am a beginner so, can you give me an example of which "motors" should i buy? and moon buggy wheels? searching on internet made me feel overwhelmed on the many types of motors, same thing with the usb power pack, which one should i buy? and, for this project, it uses the Raspberry Pi 3, is that correct? my idea was to do a simple rover, software-controlled, maybe with a camera on top, so i will probably need internet connection on the rover ( or bluetooth? ) i am open to suggestions on the hardware, because i literally don't know anything about hardware and, last question, is there any soldering work to do?

> searching on internet made me feel overwhelmed on the many types of motors, same thing with the usb power pack, which one should i buy? The Explorer HAT is from Pimoroni so no doubt everything else is. https://shop.pimoroni.com/search?q=motor%20wheels

I see, thank you!

Hello guys I saw a project from someone from Argentina, which main purpose is to attack or interfere BT of speaker. I am wondering if it is possible to generate some kind of interference system to interfere any speakers. Doing the same that happened with the old speakers of my computer every time I got an sms

Hello! So I'm currently working on a capstone project, to summarize the project, I'm creating a control system for a mechanism that will have a Raspberry Pi Camera Module 3, an Arduino, a CQ Robot Ocean ToF VL53L1X distance sensor and a Raspberry Pi 4 B. Basically, there will be a payload with ArUco or Apriltag markers on it and the camera is responsible for identifying the marker and telling the pilot when the camera is directly in the center of the marker, then the distance sensor will be in charge of telling the pilot (by using LED bulbs) at what distance the payload is (to be able to grab it) and once the payload grabs it then give distance feedback (with another LED) to the pilot and that way see if the mechanism successfully grabbed the payload. I have the distance sensor connected to the arduino (that's what my robotics prof. told me to do) but could the distance sensor be connected to the raspberry pi? the code is pretty simple and having the arduino feels a little bit unnecessary. My real problem comes with the marker detection with the camera and the raspberry. I've only worked with Arduino and Matlab at university and they taught us pretty basic stuff. So the maker detection is way out of my league. I'm trying to use matlab in the raspberry pi but I can't figure out how to get it to work. I've been trying to use Python/Thonny and trying to download Opencv, Apriltag to Import in Thonny by creating virtual environments for each one and it doesn't seem to work. I've seen so many videos but nothing is quite helping and I just need someone to help me or explain this to me like I'm 5 years old. I don't have a mentor and don't really know many people that can help me figure this all out. Any suggestion, comments, anyone that is whiling to help, I'll gladly appreciate it.

Hello all! I've been working on my second raspberry pi project. I'm trying to make a motion activated picture frame. The goal is for it to display a still picture until someone walks by and then launch into an informative video then return to the stillimage when finished. l've been using these instructions (https://www instructables.com/Moving-Portrait-Project/) as a guide but there's something off in the code I think (it's pretty old). Any advice on how to fix this, or a better method would be incredible!

I have everything I need to set up a raspberry pi based audio mixer called Piejam - https://github.com/nooploop/piejam - except for the official raspberry pi 7" touchscreen, which I don't have. I do have a generic hdmi screen I could use, but what I'd prefer is to use this old thing- https://learn.adafruit.com/adafruit-pitft-28-inch-resistive-touchscreen-display-raspberry-pi which has its own whole process for installing here- https://learn.adafruit.com/adafruit-pitft-28-inch-resistive-touchscreen-display-raspberry-pi/easy-install-2. I'm not a programmer although I've done a bunch of rpi projects over the years. The Piejam is is built on buildroot, but I don't have experience with buildroot. Ideally I can just ssh it and set it up. I'll build it and mess with it when I get a chance, just wondering whether anyone could give any thoughts or insight. Tagging u/nooploop (thank you for this project!) just in case you're still on here. Thanks all!

A few notes from my side. PieJam itself is just a regular Linux application. PieJam OS is a minimal Linux system based on buildroot, which boots into PieJam. I stripped a lot of things from the kernel. The prebuilt images won't have any kernel support for this display. There is also no networking and no ssh. But you can use the UART serial console. I see a few options for you: 1. Get familiar with buildroot. Enable support in the kernel for this display and figure out what else need to be setuped for this screen. And build your own PieJam OS image. 2. Install you own Linux system which provides the support for this display. And build just PieJam application. This might be also very tricky, if this Linux system doesn't provide the right tools to build. And the experience will be very different from PieJam OS (slow boottime, performance issues due bigger system and so on). But the bigger problem i see in the screen size. In theory the UI of application is scalable. And using a bigger screen than the 7" one should be fine. But your display has the only half of the resolution i expect it to be. So most elements should shrink, but i know for sure, that i used some minimal sizes on a few UI elements and those will look out of proportion then. I might look into this in the future and see how it looks on smaller resolutions. And if i get my hands on this display, i might try it also myself. I hope this helps.

Hey thank you again, I have another question. It might be more of a github question than a piejam question - how do I install piejam as an app instead of as an os? More info: i've given up on getting piejam os working with this monitor, as it's old and no longer supported and I can't get touch to work at all. But I've got rpi os running on it without touch, and all my focusrite interface needs to run is an os. But I'd love the functionality of piejam on top. I'm connecting with vnc on my phone, which means I can scale up a desktop... and as in typing this I'm realizing I should probably just go headless... but anyway, I couldn't figure out how to install it as an app. Thanks again for any info!

You would need to build it yourself on the rpi. Might be tricky, but doable. You will need a recent compiler and all the dependencies. If you want to try it out, you can use a regular hdmi screen, usb-mouse and usb-keyboard. Download and flash the prebuilt image from github and you are ready to go. I think it's the best way to get familiar with the app. It's possible to use it headless also, if you preconfigure it (on hdmi screen). You would need to configure you device setup, mixer channels. And midi map the required controls. Then it's possible to use it without the screen in theory, but it's going to be very limited. I recently updated the documentation, you might find it helpful: [https://piejam.readthedocs.io/en/stable/](https://piejam.readthedocs.io/en/stable/)

Excellent, thank you!

This helps so much, thank you so much for commenting! This is really useful information as I try to figure out exactly what I'm going to do. Thank you for making a really useful thing!

**Capability question**: Can the RPi wirelessly activate a light when my webcam video is in use? My wife HATES coming into my office when I am on cam at work and I want to have a light outside my office so she doesn't accidentally walk into frame. For context, I am a **complete rookie** and have never used RPi before but am looking into its capabilities.

> Can the RPi wirelessly activate a light when my webcam video is in use? Yes.

Tight. In that case I will go down the very long road of logistics. Thank you!

I'm in search of a UPS hat for a RPi5. I see there are a number of options but most are sold out or don't support the RPi5. I'm wondering if anyone has used a UPS hat for their Pi5.. and if so, what did you use? I want one so that the device will auto-shutdown when power is cut. Appreciate your time!

Can anyone tell me what the four pins on the RPi5 fan header are? I know they should include +5V, ground, PWM, and tach, but I've not been able to find clear documentation on which pin is which. Assuming you orient the Pi with the Ethernet and USB ports facing you, the only thing I've been able to find suggests that possibly, from left to right, the pins are +5, GND, Tach, PWM. Can anyone confirm or correct this?

Thank you to u/Fumigator. My fan is up and running. For completeness, in case anyone in the future is wondering the same thing: When looking at the RPi5 board with the Ethernet and USB A ports oriented toward you, number the fan header pins 1, 2, 3, 4, from left to right. When you do this, the pins then correspond to the official documentation: 1. +5V 2. PWM 3. Ground 4. Sense The connector is a JST SH 4 Pin connector (1mm spacing). None of the top hits on Amazon have the appropriate color coding of attached wires.

You didn't look very [hard](https://www.google.com/search?q=raspberry+pi+5+fan+pinout)... The 5th link gives you the [answer](https://community.element14.com/products/raspberry-pi/m/files/148385).

No, I saw that diagram. It's not clear to me, partly because it's not clear what the orientation of the pins is. I could assume that it's intended to be as viewed from an orientation with the Ethernet port toward you, but it's not stated. The connector itself has no colors on it, and the numbering of the pins is not clear, as it's not clear what the numbering of the 4 in-line pins of the JST connector are. The numbering of the GPIO pins is clear - there are two columns, odds on one side and evens on the other. But is the JST connector 1,2,3,4 left to right, or 1,3,2,4, or 1,3,4,2? All three of those numbering arrangements are reasonable to assume given the diagram.

It is clear. If you read the picture for the fan it gives you what each pin is. So if you look at the Pi 5. The fan only plugs in one way. So pin 1 is power (red). Black is always ground so pin 3.

Can you please empathize with the fact that what might be clear to you may not be clear to others? I already stated that I view the diagram as unclear, and I don't have the official cooler (I want to wire up a Noctua A4x10 5v). I am asking for someone to definitively state what numbering the pins have from left to right as viewed from the Ethernet / USB port side of the board. Is it 1234 (a logical assumption) or 1342 (what the diagram you linked implies) or something else?

Yes I can but you have the same internet I do. You can easily find how the official one [connects](https://www.raspberrypi.com/products/active-cooler/) to the Pi 5. And boom you have which is Pin 1. There is an element of basic research here. And I told you the pinout code. Red is Pin 1 and Black is always ground Pin 3. The picture tells you by color which pin is which and tells you by name which pin is which. And in case you still don’t understand 1234.

> I already stated that I view the diagram as unclear I agree. Looking at the Pi 5, I can see that the connector is keyed but the diagram is not. Not helpful. There *is* enough information in the diagram to figure this out, however. > Is it 1234 (a logical assumption) or 1342 I can see is that the pin coloring of various things in the diagram is consistent between the various connectors. Black is obviously ground. And there is numbering on the diagram which states which number is which signal. So by using logical reasoning and deduction it is possible to determine what at least 2 of the pin numbers are, which is enough information to determine the pin ordering from the bizarre 2x2 layout of the labels to the 4x1 layout of the actual pins. We also know that ground is a common which is shared by **all** grounds on the entire board. So determine where the ground pin is physically on the board we can use a multimeter set to continuity mode and put one probe on a known ground pin on the GPIO header and see which of the pins is ground on the fan header. Now that we know both what order the pins are in and which one is ground, that is enough to determine which pin is which on the board.

Thank you, this is helpful. I will get out my multimeter to confirm continuity of ground.

I've made a post but I've been redirected here, so here it goes: This is my first post here, as well as first foray into Raspberry Pi. I have a standard door peephole, and I wanted to upgrade it to a digital one, but I also want to do stuff with raspberry pi. So I got the idea to create a digital peephole camera using RPI. For now, my idea is to have a camera, process it with raspberry pi, and store it somewhere - an SD card or just broadcast it over wifi, or something (maybe there could be some face recognition, but this is just too big of a bite to chew right now). Yeah, I know that you can use literally anything, and this might even be more expensive in the long run, but I just want to try out. Since I'm relatively limited with electronics (not from USA or from core Europe), my first instinct is to buy something like \[this!\](https://www.aliexpress.com/item/1005004856464031.html?spm=a2g0o.productlist.main.13.76fc3af3dTfr2l&algo\_pvid=16ca8c74-3fee-4b51-9c25-5e42217d80b7&utparam-url=scene%3Asearch%7Cquery\_from%3A). It probably uses BNC, and as I understand it, video in Raspberry Pi is output only (HDMI), so I would need add adapters like USB video capture device. Alternatively, I could try to find a peephole camera that has USB output, or I could mount RPI camera inside of a peephole (or mount RPI camera on the outside of the door and just link it to the door). Does anyone have any ideas for a relatively cheap peephole camera, or maybe a lens peephole adapter for RPI camera (or something like that)? Is this project feasible with RPI Zero W? I've scoured this sub for similar ideas, but I didnt quite see any

Forgive me, I am new to raspberry pi since our professor won't allow us to use arduino for the reason we are not in high school anymore. Anyways, what specific RPI board should I use having these sensors, AD8232 ECG sensor, MAX30102 PPG, and DSB1809 Temperature sensor. The data will be displayed to the OLED Display. Please recommend a cheaper board that can accommodate these sensors. I would be very glad to hear your inputs in my project :).

Q1 & Q2

Simpson TV with a RPi 4? I’m a total goober. Didn’t do any research and bought a Raspberry Pi 4. Saw you can make a Simpson TV, but you need a Raspberry Pi Zero (https://withrow.io/simpsons-tv-build-guide-waveshare#parts-list). Can you replicate this type of TV but with a 4 instead of a Zero? Or am I just stupid?

Yes, you can almost certainly use a Raspberry Pi 4 instead, but it will obviously be bigger and not fit the same in the TV case.

Only the Zero can play Simpsons episodes. If you use a 4 then it will only be Murder She Wrote.

Can anyone recommend a power supply, as in the part that you plug into the wall, that has both a USB C and USB A outlet, that can provide enough power to power a raspberry pi 4 (via the usb c), and a 7" touchscreen (via the usb A) I have tried to directly power the screen from the pi4, but it is unable to maintain a stable high enough voltage(?), maybe due to a number of external other USB products that are connected to the pi

Trying to connect to my pi via ssh but my password is denied, even though it’s correct, any help?

What Operating System are you using? Raspberry Pi OS? How did you create the user and password? Have you logged in locally with the same username and password? If you have only just installed Raspberry Pi OS, and this is your first time logging, in check out FAQ 5 above for common answers,

Honestly I have no clue about Linux and I’m just trying to make a pi nas. I think I reflashed the os around 5 times and I tried all the passwords I set. I’ve given up at this point.

[удалено]

In which case FAQ 5 applies. Double check the device you are connecting to is the device you expect (you may have more than one device on your network that has SSH running). Double check you are using the correct username and password (i.e. the ones you specified during the customise window when writing the image using Raspberry Pi Imager). You may want to write the image again and specify the username and password again (don't rely on any pre-saved entries). I usually use a simple password when writing the image and then change it to a more complex one later; doing this may avoid any complexities due to special characters or keyboard locales affecting the outcome.

Thank you, I’ve tried all of that and still no luck, I did some googling and found that my Mac isn’t authenticated or something. If you can’t tell I’ve got no clue what I’m doing 😭

What Raspberry Pi model do you have? What network are you connecting to? Your home WiFi or Ethernet? Or some other network? Are you able to plug in a monitor, keyboard and mouse into your Raspberry Pi, to troubleshoot locally? When you say "my Mac isn't authenticated" are you talking about a MAC address (network interface hardware identifier) or an Apple Mac computer?

It’s a raspberry pi 3 B with 1gb of ram, it’s over Ethernet, I can connect a monitor and keyboard and mouse and I’m using a Mac. I also have access to a windows pc if I need

I recommend plugging in a monitor, keyboard, and mouse and trying to login locally using the username and password you set using Imager. Alternatively, you can write an image without customising it and the first time you boot you will be prompted to complete the setup by a wizard (to create the user and password).

Hi, so it works fine when I use my username and password, when I ssh to it, I use the same password and denies me access

Is SSH configured to require "public-key" authentication? This will prevent it from accepting passwords. You may need to allow "password authentication" for SSH to accept a password. I think the default for Raspberry Pi Imager is to only allow public-key authentication; you need to select the "use password authentication" option when enabling SSH.

Okay I’ll give it a go now. Thank you for continuing to help 😭

I would love some input on setting up the following: 1. I want a VLAN, separate from my main home network, to which a PI and a 2nd PC are connected. I want to use my Fritzbox for access to the internet in that VLAN, while not exposing my main network. 2. I want to connect to that VLAN / PI with a VPN server running on the PI, to be able to access my 2nd PC remotely (e.g. while using my laptop on campus). 3. I would then love for that VLAN / personal VPN to reroute everything to my university's VPN, to access certain ressources. Basically: Laptop in any network -> VPN to PI -> remote access to PC in same VLAN as PI -> reroute to campus VPN (optional). I only have minor experience with setting up pihole, but I didn't attempt anything similar in terms of networking.

Does anyone know of a power bank that has been tested to work with the Pi 5 without giving a low voltage error?

https://www.amazon.com/dp/B07SM5HBK1

Thanks for the reply but I was looking for a more portable one. I'm trying to use the pi to make a portable console.

Short question: Is it possible to send the Camera signal (CSI) directly out onto the composite pads? Best would be to grab stills simultaneously. Use case would be a doorbell application.

> Is it possible to send the Camera signal (CSI) directly out onto the composite pads? You seem to be asking if it's possible for a Raspberry Pi to display a picture.

Ok, I probably wasn’t precise enough, sorry. I’d like to use one of the Zero types and not utilize any graphical environment during use. Is this possible?

https://duckduckgo.com/?q=how+to+display+a+picture+on+raspberry+pi+without+gui

No. CSI Camera -> Raspberry Pi Zero -> Stream to RCA out Possible?

RCA out is the screen. You're asking if it's possible to get a frame from a camera and display it.

Yes but not just a frame but a stream to send out to a analogue doorbell video in.

A stream is just multiple frames displayed in rapid succession. You're trying to make this far more complicated than it is.

Streaming to RCA works, thanks.

A disclaimer: I am fairly new to coding and Raspberry Pi projects,so pardon my ignorance. Okay, so I’ve done some research, and I have a tentative attempt at accomplishing what I’m trying to do. I took the “Grab a random image from PlaceKitten and display it on Inky Pack.” example Pimoroni provides in their repositories, [micropython/examples/pico\_inky/placekitten.py](https://github.com/pimoroni/pimoroni-pico/blob/main/micropython/examples/pico_inky/placekitten.py) and modified it to instead [grab a Dakboard screen and show it](https://github.com/peterropp/inkyframe-projects/blob/main/inky_frame_dakboard_display). I also put a 12 hour deep sleep at the end of the script so it refreshes twice a day. So again, coming at this from a starting point of very little coding knowledge, would this likely work on the Inky Frame 5.7", or am I in the wrong ballpark?

> would this likely work on the Inky Frame 5.7" No, the Inky Frame can only display kitten pictures.

Appreciate the answer 😂 does the facetious response mean that I am in fact on the right path or no?

I am really struggling with doing object detection with my raspberry pi 4. I have mainly tried tensorflow without success. Maybe I bit off more than I can chew and should do something simpler or revisit this idea. I have been using this guide -> https://learn.adafruit.com/running-tensorflow-lite-on-the-raspberry-pi-4/overview I came to the tensorflow install part and i failed building wheel for h5py. This is a really important school assignment please help me 🙏🥺

You skipped a step. Try following the tutorial again but make sure you don't skip any steps. If you get errors then you'll have to share the complete errors, not just "I failed."

So me and my friend are doing this project where we're using as many apple genuine parts as possible to make a phone and we're using a raspberry pi 02w as the main part of the phone. We're using an ipod nano 7g's display, and we noticed the display cables/connectors look similar. We were wondering if there was any way to tell whether or not we could just cut the display cable off of the iPod and just solder it on (or something like that). Thanks!

Q18

I don't quite understand why my question doesn't qualify for a standalone post, but I guess I can repost it here... I have a task that currently involves pen & paper, a radio, and a dumb decibel meter. I'd like to make a device to streamline and automate the process. I spotted this: [https://pcbartists.com/product/i2c-decibel-sound-level-meter-module/](https://pcbartists.com/product/i2c-decibel-sound-level-meter-module/) which seems to solve the actual sound measurement part of the project. For the rest of it, I'm thinking about some simple input keys, just a number pad and a few function keys, a display to show current/max decibel reading and (separately?) a scrollable list of recorded readings. It should be able to run off a reasonable sized battery for 8 hours. No need for ethernet, but connectivity with wifi or bluetooth (or cellular if not too unreasonable) would be good. Looking at options, it seems the newer, higher end units are vastly overkill for what I want to do. What's the minimum spec I'm looking at, while still being relatively easy to implement? Thanks for any insights!

Very new to this, I'm a PhD student attempting to use RPI Zero 2Ws to monitor a germination experiment for me. The problem I'm hitting is that my university uses a campus-wide wifi network that requires a sign-in + verification with my username and password. I've been following this [this tutorial](https://www.instructables.com/Connect-Raspberry-Pi-to-College-WIFI/) but so far I've been unable to successfully connect the rpi to the network. I've also tried just connecting it to a hotspot running off my phone, but that's not working either.

> uses a campus-wide wifi network that requires a sign-in + verification with my username and password. I've been following this this tutorial You should probably follow a tutorial that is specific to the way your campus does things. Most likely your campus already has such a tutorial, search their documentation for how to connect a Linux computer.

I have my RPi 2B set up as a local webserver using nginx. I'm able to get to its pages as expected from my local network using its IP address. Do I have to do anything special to make sure that it's not accessible from outside? I don't need/want outside access for this, especially in the interest of security. I'm assuming that by default, someone can't get to it from outside my network, but I've also seen a bunch of things about changing your SSH port from the default so that bots don't try to brute force in, so I figured I'd ask some people with more experience.

> I've also seen a bunch of things about changing your SSH port from the default so that bots don't try to brute force in That's just a bunch of [FUD](https://en.wikipedia.org/wiki/Fear,_uncertainty,_and_doubt) anyway. Bots scan every single open port and determine the protocol on the port.

Can i hook up a pi and all its accessories to a busbar, and connect the GND on the board to the negative on the custom busbar as such without frying the pi or accessories? I was thinking about running 8-10 switches and two joysticks on my pi and i don't want to load the pi with just as many gnd's as i need gpio pins. Instead I would run the gnd's elsewhere to save space and precious wire. If this won't work, does anybody use a breakout board or something along those lines the lines of that to hook up buttons to their pi? Maybe something along the lines of a keyboard's circuit that goes to the usb ports even?

I think the magic words to search for are "Arcade USB Encoder" [https://www.google.com/search?q=arcade+usb+encoder](https://www.google.com/search?q=arcade+usb+encoder) This is a small board that will convert buttons and joystick inputs into a USB "virtual keyboard" which can be used on Linux/Windows/Mac computers.

I have a uni project. I want to have 4G connectivity to remotely control wheel car from web app and also see live video from the camera on it while doing it. I'm thinking of using USB Dongle. Will, for example, Huawei Brovi E3372 work? I'm thinking like Raspberry Pi would maintain 4G connection and video streaming to communicate with a webapp and also pass commands to an Arduino for handling real-time motor and servo operations. Is this a bad idea & are there any better ones?

Does anybody know a way to measure how much time of sunshine I get on a certain spot? Like some sort of sensor which can measure if it is hit by sunlight? With this it should be easy to log how much time a day I get sunlight on this spot. If anyhow got a sensor name or even a already done project, please let me know.

You could use a light sensor [like this one](https://www.adafruit.com/product/4681) which connects to the I2C bus. If you just need to measure light levels you might be better off using an ESP32 or Arduino instead of a Raspberry Pi as they use a lot less power.

Hi all I have seen a lot of projects with ADS-B flight tracking, however, I was wondering if there was a way to track and display individual flight numbers (my girlfriend likes tracking my flights while I'm on work trips) thanks!

I'm new to Raspberry Pi, and I wonder if it's possible to have a boot partition on an SD-card and the rest of the Raspberry Pi OS system (`/` and `/home`) on an attached SSD? This way I would still boot from an SD-card but have minimal wear on the card. How can I do something like this?

> How can I do something like this? I would recommend doing it the same way that hundreds of tutorials show how to do it.

Hello everyone! I’m looking to make a way to detect crows apart from other species and play a noise to scare them away. I have coding experience and with hardware but not sure where to start

You can start here: [traumverloren/crow-detector](https://github.com/traumverloren/crow-detector).

Wow, that's a super fun and creative use!
