I am a researcher-maker-hacker focusing on Computer Graphics with a #retro, #fpga gaming twist. I am also very much into #3dprinting and #electronics.
These days I enjoy making #graphics hardware on fpga, using a language I developed, #Silice

I finally got around to doing another Surfer release, so now we're on v0.4.0 🎉
My personal highlights are the new web assembly based translator system, and the improvements to our waveform control protocol, and you can read the full change log at gitlab.com/surfer-proje...

WolFPGA on the icepi-zero! Works great!! ( #Wolfenstein raycaster on #FPGA, no CPU, pure graphics, in #Silice)
It is a very neat board, packed with features. (Silice already has support, check it out!).
Crowd funding still open for a few hours, check it out :

A fantastic result, finally getting rid of layers, filling the part with optimized free-form (well spaced, near constant flow) paths! "Spaghetti"? Yes, but these are ordered in a sequence and can print without collisions. Amazing work by the team!

1/3 Pro-tip: (WebGPU + Emscripten) if you are wondering why your mapped buffer contains only zeros, make sure to use wgpuBufferGetConstMappedRange on your WGPUBufferUsage_MapRead buffer.

I finally got around to testing the second project I had on #TinyTapeout 06. This squeezed 64 bytes of RAM into a single Tiny Tapeout tile (roughly 160x100 um). It works!

I love the RP2040 and RP2350: amazing, useful tiny chips.
Thus I enjoyed watching this talk on how to hack the RP2350. Goes into lots of hardware details. Sure, it means the RP2350 is less secure than we hoped, but I trust a new revision will soon correct this!
