announcing... the waterloo hacker fab 📀 four months ago, a group of friends & i set out to build a diy chip fab @uwaterloo ! so far, we've built a lithography machine, achieved micron-scale patterning, and have secured ~$16k to build the rest of the fab. more details below!

inspired by cmu's chip fab, our first step was to build a lithography stepper. we repurposed a movie projector as our uv light source (adding custom optics + led pcb), built a spin coater & developed a basic chemical process. the result? patterning our logo onto a wafer

the 200x compression ratio... now, let's address the 200 compression ratio. the goal of 200 lossless compression seems rather arbitrary. there's no need to keep all data samples when processing electrophysiology data. last year, @anushmutyala and i wrote an extensive article

why did bz2 perform well? bz2 performed well, achieving a 3.11 compression ratio and increasing data entropy. the burrows-wheeler transform arranges data into similar character runs, and the move-to-front transform reduces redundancy. these methods enhance compressibility by
