As the other part of preparing to learn how to design an analog synth I created my first little PCB which was a great learning experience. I made a little tiny breakout to an io expander :>

My latest project I've been very interested in learning electrical design (as a firmware engineer) and as a venue into exploring that I've been getting into learning about analog synthesizers, and built the DIY MKI ex ericasynths eurorack to practice my soldering and its a great little beep machine!
