I bought a raspberry pi 5 when it came out. I've never managed to boot it. Sad, isn't it?

When I launch the raspberry without USB storage or SD card, I get this information.

As soon as I connect something, be it USB storage or SD card with any system (raspbian, debian bookworm, home assistant, anything!) the menu doesn't even appear any more, and all I get is: a black screen / or nothing, as you like.

Help!

I have started to implement serial uart in programmable IO. It may come useful for someone who has their PCBs printed with serial connected to wrong pins.

Hi everyone!

I’m planning to repurpose an old computer case to house a few Raspberry Pis and could really use some advice.

First, I’m trying to figure out the best way to mount the Raspberry Pis inside the case. Are there any good DIY solutions, or are there premade mounts designed for this kind of project? I want them to be secure but accessible if I need to make changes.

Next, I’d like to power all the Pis centrally. Is there a way to do this efficiently without using separate power adapters for each Pi? I’ve heard of some solutions involving custom power supplies, but I’m not sure where to start.

I’m also thinking about cooling. Would the case’s old fans be sufficient, or should I add heatsinks or other cooling methods to each Pi? I want to make sure everything stays cool, especially if the Pis are running intensive tasks.

Finally, what’s the best way to handle I/O? I’ll need to route HDMI, USB, Ethernet, and other connections out of the case. Are there panel kits or other ways to organize the cables neatly?

I’d love to hear your suggestions or see examples if you’ve done something similar. Thanks in advance for your help!
