You can connect PATA drives to a CH32V003 microcontroller if you try hard enough. Even had one GPIO pin left in the end!

I wrote a custom network stack in C to run on my custom silicon RISC-V core, supporting both IPv4 and IPv6 and its now good enough to make HTTP requests. But maybe I'll turn that around and have it accept HTTP requests. We'll see.
feat. a really ugly bodge to prevent over-current on the memory bus

need people to stop making technology inspired by Star Trek (smooth, sleek, no buttons, all screen, voice activation, extremely minimal, wireless) and start making technology inspired by Star Wars (clunky buttons, indicator lights on everything, ugly, indestructible, fat cables that emit steam)

Its a bit all over the place and somewhat cursed, but ya'll will now be able to read about my most complex and most bugged custom EF Con Badge yet.

I am once again running large algorithms on hardware that was never, in anyone's dreams, designed to handle them!
This time: LLM on a Z80.
This took a really, really long time, so I hope people will at least find it funny.

Today, I successfully fit a whole DDR2 memory controller into a $1.50, 240 LU CPLD. It is ungodly slow, but appears to work without dropping bits. Lots of optimization left to do, but still got 25% unused space on the CPLD. github.com/89Mods/mini-...

You can now do real astronomy in my Avalon #VRChat world now that the telescope is adjustable with a working viewfinder, and get amazing views like this one. I also updated OpenFlight and the video player can now play side-by-side 3D videos.

TinyTapeout chips finally got delivered! This is where my whole journey into custom silicon began, so kinda ironic I’m receiving this long after my first fully custom ICs from GFMPW-0. Still, gonna do my best to test all of my designs on there.

New post up on my website about that one time I built a turing-complete computer around a 1-bit CPU. People keep telling me it has sigbovik vibes, so it must be good. tholin.dev/mc14500/

This weekend, successfully revived a MCU from the GDR. The cursed staggered pins required a custom PCB. The extra pins are for an external ROM, as this is a dev version for a part that has a mask ROM. 8MHz, runs VERY hot, which is bad for a MCU, but consistent with other GDR ICs I own.

Hello Blue sky! For those who don’t know me already: I build fun things in both VR and RL. Migrating here from THE OTHER PLACE. Hopefully I can just pick up where I left off.
