I just got my friend Leo Moser's custom GF180MCU Fabulous FPGA board, produced by WaferSpace. It already has a design loaded, so I'll be playing around with it over the next few days and see what I can build with it. A custom FPGA is just insanely cool. Leo is an absolute legend.

On my way to HeiChips Summer School 2026. A whole week of open-source chip design! https://heichips.github.io/

Another project that was originally on TT09: a run length encoded video player, this time with audio! Here it is playing Bad Apple, audio captured through my phone’s terrible mic. Unfortunately only the first minute fits on the 16MB flash this time as the audio […] [Original post on hachyderm.io]

TT sky25a also has a decoder I made for 8b10b encoding. This design allows two 8-bit numbers to be decoded and then multiplied together. This came about from discussing how fast a standard Tiny Tapeout design could be clocked and still reliably receive data (preferably from the RP2 on the […]

Besides TinyQV I have several other designs on the sky25a Tiny Tapeout chip, and so far they seem to be working well! My first attempt at designing at the transistor level went well: I made a half adder and then manually placed and routed that into a 16-bit counter, using a flip-flop from the […]

wafer.space Run 2 is now officially in production! 🥳🚀 In short, wafer.space (https://wafer.space/) offers low-volume silicon manufacturing of 1,000 custom silicon chips for the open-source GF180MCU process. Like last time, this shuttle features some […] [Original post on fosstodon.org]

I received the #TinyTapeout sky25a chip, that has the RISC-V peripheral competition versions of my TinyQV SoC on it. There’s lots to play with here, and it’s great to see things are working well. Micropython launches at up to 90MHz, which is faster than […] [Original post on hachyderm.io]
