Flash Raspberry Pi OS onto NVMe SSD from a Micro SD card
I am looking for a way to format/flash my SSD for my rpi 5. I don't have a usb/ssd cord to plug into my computer, and I am hoping to be able to do something like run raspberry pi imager as a cli tool and format the ssd while it's plugged into my rpi 5.
Has anyone done this? What did you use/how did you go about it? I don't have any micro hdmi's either, so I am looking for a headless way to do this.

rasberry pi and pygame
Hi. So for a project for school I’m thinking of using a breadboard as a controller for a game I made in pygame. I want to make a controller with a breadboard and buttons. If the player presses the button, it moves the character. Is this possible before I start?

Timer that can detect game usage
Hey all. Trying to make a timer that when plugged in, times how long I've been playing a game and after a set time, say four hours, it'll start making a loud noise.
I've got the raspberry pi pico, a breadboard, headers, wires, speakers, soldering equipment. Now I just need to know what to start doing.
Any help is greatly appreciated.

What Pi do I use?
Hi! I want a raspberry pi to show a simple dashboard to a screen - it has to get data from an api.
It would also be cool if I could host my discord bot on there
so, requirements:
python

Which Raspberry Pi do I need to use?
Hello,
I am new to Raspberry and I would like to start working with it.
Basically I want to start learning how to use and program it (I already know how to do the electric stuff so I only need to learn the usage and programming of a Raspberry Pi).
After learning the basics I want to build a small device, which searches for traffic signs outside my car and displays them onto a small display. So I need a Raspberry Pi that is able to run the camera module and a small rgb display.
It would be great if a Raspberry Pi like the Nano or the Zero could do that, sadly I dont really know which Raspberry is made for which purpose. It would be great if someone here could help me so I know which Raspberry I need to buy?
PS: I want to program the software in Python if that would be possible.
Greetings Leander :)

My Raspberry pi pico w is making a weird sound when powered from vsys
Hey everyone,
I'm trying to power my pico w with 3.3v vsys via a seeed studio lipo rider plus. I have a 1.8inch spi display connected. When turned on the pico is making a humming noise. I have attached a recording of it. I just want to ask if the pico has gone bad or should I connect 3v3_en to make it work.

MLX90640 Thermal camera breakout and Raspberry pi 4
Hi all, I'm a total noob building a raspberry pi 4 camera setup. I'm a programmer with previous (limited) raspberry pi experience.
I've been following this tutorial https://tomshaffner.github.io/PiThermalCam/#hardware-setup and I have all the listed parts. But, I don't know how to do this diagram [first image attached].
The wire [second image attached] has connections for the raspberry pi pins on one side (4 individual) but I don't have a clue what the other end is or how it could connect to the Thermal camera.
Is this something I can achieve without soldering? Do I need any extra parts? After extensive online research I'm not finding any clear step by step tutorial that goes into the hardware side of things here.
Thanks! Please @ me if anyone has any ideas 😊

Compiling QT code for the PI 5
Hello! I am very new to QT and Raspberry Pi in general. I'm working on a QT project that i want to run on my RP5.
The issue is that I can't seem to figure out how to compile my source code for the PI. The boot to QT option doesn't support the PI5 yet. I tryed to install QT creator on the raspberry itself but I have encountered issues. Can someone please provide some guidance, please?
The project requires the use of sensors that use I2C and SPI. The QT version i am using is 6.6.3

Issues with bh1750fvi light intensity sensor
The sensor is connected to my raspberry Pi 4 breadboard through the following pins:
Sensor > Breadboard
GND > GND
SDA > SDA1
SCL > SCL1
VCC > 3.3V
The I2C interface is enabled.
Whenever I run the i2cdetect -y 1 command in terminal the grid is returned empty and not detecting the sensor.
Would appreciate if anyone knows how I could fix this issue. Thanks.

Trying to Recreate Project
I found a project on Reddit from two years ago called "Love-Box" and it is for creating a simple system of being able to wirelessly send images to an E-Ink screen connected to a raspberry pi zero from a Firebase website/app(I think?). I am super new at coding stuff especially on the PI and the instructions given are not detailed enough for me to figure out what needs to go onto the PI and or what needs to be done for the app/website. I was hoping someone could look at the reddit link (which includes a GitHub link) and give me more detailed instructions? I really want to make something like this for my boyfriend.
I thought about contacting the creator but he has not been active on reddit for about a year it seems. By more detailed instructions I mean that I do not know what needs to go onto the PI or ran on the PI from the three files. I know the LoveBoxUI is for Firebase, but the other two I am not 100% sure. I am basically looking for some dumb down step by step instructions or to the best of anyone's ability.
I am using the same parts as listed except I am using a Pimoroni Inky Impression 5.7" screen instead.
Any help is appreciated!

So here the thing, this code only works only once after I run the program, how can i make this thing work again for like 3 minutes or so. anyways here is the code
py

if currentname != name:
currentname = name
print(currentname)
#Take a picture to send in the email
img_name = "image.jpg"
cv2.imwrite(img_name, frame)
print('Taking a picture.')
#Now send me an email to let me know who is at the door
request = send_message(name)
print ('Status Code: '+format(request.status_code)) #200 status code means email sent successfully

Green light issue.
Currently setting up my pi zero w.
Right after flashing raspberry pi OS however only the green light is on. Seems to be blinking every 800ms or so. Any ideas?
Looking into issue.txt it has 1 log from 2024-03-12 which is weird considering I didn’t have it then. Could this point to some pre installed software having issues? Any help is highly appreciated :D

2 raspberry pi 4s not booting anymore
Hi, I have 2 raspberry pi 4's and they are not booting anymore. 1 pi shows a solid green and red light and another only a solid red light. The power to the gpio pins work. I think that it has to due with a charger that I used with it. Is there anything I can do to troubleshoot?
