Things I've Built

Covid ventilator Breezy

At the time everyone was building them, I couldn't resist. This is my version of a makeshift mechanical ventilator.

Hybrid rocket engine test bed

I have worked on electronics and firmware for the rocket motor test bed. This was so much fun!

Hollow table 3-axis CNC mill

I often needed to machine tall parts, that did not fit my machine... So I've created this one. The parts can be mounted inside the frame to be machined.
