ibook G3 ipad case from Adafruit’s guide learn.adafruit.com/ibook-ipad-case Cost only half of that magic keyboard case but way more chic.

Valuable info on how SNES renderer work from @fabynou fabiensanglard.net/snes_ppus_why/ Cant find these info when working on my FPGA PPU. Nintendo's engineers do optimize every bit. I also use double line buffer and cut short on everything. Life is also easier with BRAM than VRAM.

Testing RTX4090. Computing Julia fractal using CUDA at 4K, doing 1,200 iterations for each pixel. Draw it as a texture quad using CUDA/OpenGL interop. Got around 10-15 fps. Code: github.com/pongsagon/Juli…

Try render raytracing scene from "Ray tracing in one weekend" book in text mode using Console command prompt API. Render at 120x60 character, 10-level gray scale. Using Console to draw something is much easier than using OpenGl or SFML.

Can anyone tell me why Kria KV260 ($250) is much cheaper than Genesys2 ($1,000) but has much higher spec?

My desk setup. Why buy a new iMac M3, when you can get a functional iMac G3 and a functional Macintosh Plus with half the price.

TinyTapeout chip! A dream come true for amateur HW enthusiast like me. Hopefully the design will work on the real chip. Thank you @matthewvenn @UriShaked for this exciting project and many helpful people on the opensource HW and TT discord community.

Voxel Space terrain rendering technique from Comanche 1992. Give better result than using polygons. Following the method of Sebastian Macke on github.com/s-macke/VoxelS…. Can run at 10 fps on #Adafruit #RP2040 with DVI microcontroller

#TinyTapeout 7 submission, 8-tile! The tiniest ASIC GPU, that can render only 1 triangle. Tested on Basys3. Hopefully it will work well in ASIC. Project submission page: app.tinytapeout.com/projects/688 Thank a lot to the TinyTapeout discord community.
