How to control when RPI camera IR Leds are powered
I've just setup this night vision camera with my RPI
https://thepihut.com/products/raspberry-pi-night-vision-camera
But I have an issue that whenever the raspberry PI is powered, so are the LEDs, this leads to them heating up when the camera is not actually in use (the PI is used for a home hub as well as camera)
While this heat may not matter much, I would feel better if I could control them, and only have them on when I want to use the camera.
Is there any software method for disabling power to the camera until I need to use it? Or any other software method around this?
If no, what would be the simplest hardware method for limiting camera to the power when I'm not using it? (I'm much better at software than hardware)
Thanks!

USB TYPE A onto raspberry pico
I want to add a usb type A onto my Raspberry pi pico W. I thought about just soldering the usb type A connector onto the board and then connecting the correct pins with wires. But im not sure if that is the best way. Also, what are the correct pins XD? I don't have a D+ or D- so is it even possible to do so?
yes I am a newbie 🙂

pi doesnt boot to os when gpio screen connected
First time setting up a pi, when using vnc, ive had no trouble booting to and navigating the OS, however after following the waveshare guide for installing their display drivers, its able to show some of the boot junk, but eventually just turns and stays black.
Completely inexperienced with this stuff and haven't been able to find the same issue online

PI 4 runs 24/7
Hi, do you think it's a problem for the Raspberry PI 4B / (I think 4GB ram) to run 24/7? I run a python script on it that also runs 24/7, (but mainly for timers to wait, so it only really executes an active thing about every 2-3 hours (which takes about 5 minutes) and at night it just waits (again with a timer) for about 8 hours. Theoretically, the PI has to work continuously because the timer/countdown is running. I have no cooling. I have PI 4 case (plastic) and the normal/official PI power supply.

RGB led raspberry pi 4 on base hat
Hello, I'm a student in computer science and we got a project on a raspberry pi. My group and I decided to do a connected lamp so we asked for RGB led and they gave us 2 chainable rgb led v2.0. but from what we looked it work with grovepi but we don't have it. I don't know how to make the RGB led change color or even turn off and the teacher doesn't help us. I tried to use the code of the grovepi but we don't have the di_i2c library which is used everywhere in the code. The other RGB led works on a white board and 4pin so it doesn't help. I'm totally new and don't know what to do, so if there is someone that would be willing to help, I'll be grateful.

Looking for a 64bit display driver for this HAT
Bought this HAT kit for my RPI Zero 2 W ( https://spotpear.com/index/product/detail/id/721/no/666.html ), included documentation only links to a 32bit display driver ( https://spotpear.com/index/study/detail/id/631.html ). I need to run a 64bit OS on this machine, and I was wondering how I would go about finding another compatible display driver for this device.

Can't get the USB-C port to work as OTG
Hi, I am working on a project that needs to use USB C port as OTG. I bought a power hat (X735 v3) to power the RPi4. I am using Raspbian Bullseye. I added “dtoverlay=dwc2” to config.txt, “dwc2” to /etc/modules, and used “sudo modprobe dwc2”. Dmesg says:
[ 3.806204] dwc2 fe980000.usb: supply vusb_d not found, using dummy regulator
[ 3.806633] dwc2 fe980000.usb: supply vusb_a not found, using dummy regulator

[ 4.014966] usb usb3: Manufacturer: Linux 6.1.21-v8+ dwc2_hsotg
however, dmesg-w doesn’t show anything when I try to connect something to the port (phone, USB stick).
What should I do? Could this be a hardware issue?

Pi 4 - Pytorch - Segmentation Fault
Hi there, I built a machine learning model that detects licenses plates. Everything is working fine on my main laptop machine, but as soon as I try runningit on the PI and try passing the tensor into the first convolutional layer I get a "Segmentation Fault" error.
Happy to provide any information that wil help debug this!

Smart Colector Robot
I am currently making a robot with raspberry pi. Things are going well. But I got two problems recently... The bot has an AI that takes photos and recognizes objects, it also has a robotic arm. I tested these features outside the Pi and they are working. I used the AI in my PC and controlled the arm with an arduino. But in the rasp I am getting these problems:
1- I am trying to connect my Raspberry Pi Zero 2 W to a USB Webcam. I tried to use the fswebcam pack to control the webcam, but it doesn't have the pallet that my webcam has. YU12. What can I do instead?
2- My python code is returning GPIO Busy error even with the system rebooted. What could be making it happen? How can I solve this?
Can someone help me solve these problems?

livestream and motion detection?
Hello, so I have a question and need a little help/ inspiration please. 🙏
Can I livestream and perform motion detection at the same time on the Raspberry Pi 4? My plan is to use a Raspberry Pi 4 with the Pi camera to send a livestream to an app and also run a program that detects motion, recognizes it, and provides the appropriate output. For example when the cat moves I get a message „hey cat is moving“ idk.
However, I've encountered some difficulties. After researching extensively, I came across a post where someone mentioned that it might not be possible because these are two separate programs.
Live-streaming and motion detection. Thought I could do all in one but doesn’t seem like that.
Now, I have another idea. Can I send my livestream to an online server (idk which one would be the best yet) and run my motion detection program over the server? or should I continue trying to handle everything on the Raspberry Pi alone? What would be the best practice in this case?
I‘m so overwhelmed with these. It’s my first raspberry pi project and I thought I can handle it with tutorials and docs but most of them are already out of date 🥲👋
Thanks in advance! 🙏💯

Which Raspberry Pi (board + camera) for Image Processing Project
Hello! I am currently a university student and have a project in mind that is based on image processing/CNN model. I have looked a bit online to see which board and camera I should use. I think for the camera I will just get the raspberry pi camera v2 but I still haven't decided which board I should use. I think I will need to get a MicroSD card as well if the model turns to be too big. I will also need to connect a gas sensor on the board later on in the project.
My budget is around 200 pounds for all the components but could potentially go a bit higher
Does anyone have any ideas on which board would be better in my case?
Thank you in advance! Have a nice week

Current draw 0.5-1 A. dc motor. 5v power source. proFET
Ok so I have a DC motor with a 3.7V battery which draws 0.5 A on normal load. Turning two rotor blades. It is from an old hover robot toy.
I have this https://www.infineon.com/dgdl/Infineon-BTS410E2-DS-v01_01-en.pdf?fileId=db3a304331c8f8560131dcc9fc520e21
That I use for switching. It requires 4.7V from the main power supply to operate. So I have replaced the battery with my own batteries. I have run it with 6 and 9 V batteries. On different occasions of course.
I switch it using one of the 3v3 gpio pins on the rpi4, gpio24. Works perfectly.
My question is this, would one of the 5V pins be able to support the current draw of the motor? I could try it I guess because I think the flywheel diode or some of the other protective features would protect the pie but I thought I could ask first just in case.
I was told that it wouldn't be able to support the current draw. My assumption is that if it can't it would result in a V-drop, making the FET inoperable. I have seen people using transistors with 3v3 pins where they used I=0.016A to calculate R to not damage the pin, but is that the hard limit for A both in and out on all pins?
Any way, again, could the 5V output support approx 0.5-1 A draw, when being hooked up via the FET in the link?
