HAT Upcity Lite rulezzzz! 😎

PCB design rule: pay attention to the details.

Much better now, especially with the fish :)

It seems that together we managed to solve this annoying shortcoming. This is a very good example of the Raspberry Pi community working together for continuous improvement. Special thanks to: Jeff Geerling Smart Home Circle Raspberry Pi RnD team - timg236

We are approaching the end of the year. What will the new year 2025 bring? I am very positive and I am looking forward to it. I deeply believe that it will bring many new experiences, and positive events and will be an important stage in our development. But it is only up to

Making a PCB layout for a few high-speed interfaces with proper inter-pair spacing and inserting a pair of GND vias (vis stitching) for good EMI performance is not a trivial task. I always treat drawing traces as an engineering art and put a lot of effort into it. I hope that in

I'm spending the next few days in the mountains with my family. This is the time I'd also like to spend catching up on reading books. Here is my list: Holiday, Ryan: "Ego Is the Enemy" Viktor Frankl: "Man's Search for Meaning" Syed Matthew: "Black Box Thinking" Regina Brett:

Happy 50th birthday i4040! After the first macro shot, I inspected the chip using my Leica light #microscope-results below. JO IT EL 4040 (C) Intel 1975 Next: metallurgical microscope pictures! 3/n

Folks, I think we have done it! If overnight tests are confirmed we have OPEN SOURCE DeepSeek R1 running at 200 tokens per second on a NON-INTERNET connected Raspberry Pi. A full frontier AI better than “OpenAI” owned fully by you in your pocket free to use! I will make the Pi

Seeing the video where Jeff with such an emotional and heartbreaking voice thanks Don for his entirety works me want to cry. I couldn't have said such sincere thanks better myself, so all I can do is paste a quote from the video below. "Don, for myself and for everyone else in

pineboards in the house!

Someone just reminded me that I used to enjoy DIY projects. It's a shame that this adventure ended this way. I don't know if I'll come back here again.

Sometimes I have the impression that PCB layout is a multidimensional chess game (the number of potential moves on many levels is huge and the opponent is very demanding). Even if you have a 8L stackup but only with TH vias, your possibilities are very limited on a 2-dim surface
