Is my raspberry Pi 3b+ dead?
Is my raspberry pi3b+ dead?
I'm using my Pi to make a mars rover using an l298n motor driver. The l298n has a separate usb power source, and the pi has a different one. While connecting the ground of the l298n to the Pi's ground, I think I connected it to the wrong pin (not entirely sure). The lights dimmed, and i pulled out the jumper wire almost immediately. I was pinging the pi from my PC, and it started showing the no route to host stuff. An SSH connection was on, it got disconnected. I decided to reboot my Pi by directly removing the cable (I had no other choice). And then, this happened. I was powering the l298n and the pi with USB cables coming out of my PC.
My pi just shows the red PWR light when a power is connected, and the green ACT light does not turn on at all. There is no damage to the SD Card reader, and I tried booting from a USB with no luck. Nothing gets hot, nothing is displayed on the HDMI, as if the pi is dead.
Is it really dead? If not, what can I do to fix it? I really need it fixed fast.

PiGRRL
hi. i'm thinking about building a PiGRRL, but i have a couple of questions about the components,
-Screen 2.8" PiTFT Plus, can i use a different screen? i dont want a touch screen and 35$ is a bit too much, any advice?
-charger PowerBoost 1000 Charger -> is there a cheaper board that can do the same? can i use these? https://www.amazon.it/AZDelivery-%E2%AD%90%E2%AD%90%E2%AD%90%E2%AD%90%E2%AD%90-TP4056-regolatore-carica/dp/B07D2G345P/ref=sr_1_8?__mk_it_IT=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=1NXV1XAO0RPEC&keywords=PowerBoost%2B1000%2BCharger&qid=1693485926&sprefix=powerboost%2B1000%2Bcharger%2Caps%2C155&sr=8-8&th=1
-2500mAh battery, the adviced one is only 4.2 volts at peek, im not sure it can power the pi quite well, what do you suggest?
i would be able to redesign the printed parts to fit the new components in case

got a Libre computer board, an GALL-h3-CC and this little 2 inch led stv7789v but can't connectem
I've scoured the internet in order to plug these two together, l've referred to the pin out diagrams of both these things, and I know that libre and raspberry pie are not one and the same but I'm praying someone here knows more than me. This cute little emulator set up was a gift from my best friend so I'm kinda outta my element here<:sadblob:1021204158587600916>

This might sound crazy but is it possible to make a full qwerty keypad for the pi pico?
Hi so I've been wanting to make a little pocket dos/basic inspired handheld computer system inspired by the ones from the 1980s and early 2000s pdas and I want to make a blackberry style qwerty keypad for it. Does anyone have any advice for making qwerty keypads while saving as many gpio pins as possible as I need as many pins for the other elements of the system. I am using a raspberry pi pico to make it.

PA system announcer [Total beginner]
Hey all! I'm brand new to Raspberry Pi and I have 0 experience with them, but from what I know, I think they would be the best option for my project, which goes as follows:
- I need a device, that will play a sound through a PA system at set times. 9:00, 11:00, 13:30, etc.
- It should choose a random sound every time from a pool of possible files in a folder, and each time should be able to have its own folder, so that they can have different types of announcements.
- and lastly, it should have a 3,5mm aux output on it.
I think this should be possible with a Raspberry Pi, right? And if it is, I would love to hear any recommendations for what I would need for it, and what has to be done to set it up!
As I mentioned, I've never done anything with Raspberry Pis before, so don't be afraid to write things in uh, a simple way. 😅

Trying to setup an alarm system with raspberry pi hardware
How do i facilitate communication between pico w's and a pi4 over wifi? I am trying to have the picos rigged up to sensors that are connected to doors. I was wondering how I would go about having those picos send data from the sensors to the main rpi4 unit that will power the alarm interface and backend. Thanks for any help.

I cannot get the raspberry pi zero to boot
I tried multiple times, I image the operating system onto the microSD card from my computer using a usb reader, then I take it and place it into the raspberry pi. After a few seconds some things display saying "raspberry pi" and a graphic. Then sometimes it reboots but it never boots to the actual desktop and remains at a black screen. The LED on the raspberry pi is solid green/yellow when I leave it to boot (while its on a black screen). I don't know what else I can try.

help making custom rapsberry pi os system
Hey, I’m here for one purpose and one purpose only I’m trying to make my own raspberry pi custom OS system. This OS system would be a program kind of like chat GPT I mainly focus on machine learning type of things and be more of an assistant. All I basically need help with is the overall necessity such as a kernel8.img, boot loader, main, and etc so I could at least put the SD card in and it would just at least execute the program. if you could help me with sending messages and a couple of other things like installing programs, I think that’s all I need for the most part I think after that I could catch on.  i’m aware that the raspberry pi does not have the power to obviously run major servers in the future. I might consider applying add-ons to the raspberry pi or maybe something else. But for now I would really love some help developing a custom raspberry pi operating system. Also, would like to mention that this custom OS I would really love to run possibly tensor flow models if you’re able to provide any other resources on this, I would greatly appreciate it .
Thank you

Connection refused Nukkit Minecraft Server
So I'm having following problem: I created a Nukkit Minecraft Server with instructions from the internet. Now I can't connect to it even though the server is running. The only thing I changed compared to the instructions is the port, I'm running it on Port 9090
Could it be a firewall problem? Because the error I'm getting says "Connection refused"

Rechargeable battery for a raspberry pi 3 model b+ mini laptop
I will probably ask more questions on this project, but For now I just want to make sure I don't either 1: Fry the batteries or 2: fry the pi. Bonus points if its relatively compact. Even more bonus points if it's super safe and easy.
