Hi! My name is Matthew and I am a electronics and software engineer, recording musician, and proprietor of Extralife Instruments. I enjoy all things D.I.Y. and have lived in San Francisco since 2011. On this website I share some of my projects. You can find some of my hardware, software, music, and videos below.
In September 2023, I traveled with my friend Brian to northern Washington for an expedition to Mt. Baker with Northwest Alpine Guides. Baker is only 10,781 ft tall but heavily glaciated making it an ideal spot to begin alpine mountaineering.
I recently prototyped an interactive “trading desk” interface in CRT monochrome for use as an easily-customizable film prop for 1980’s-themed movie scenes.
I built a free browser-based drum machine using the WebAudio API to celebrate 9/09 day 2022!
My new Studiologic keyboard is a great compact stage piano and synth, but it’s missing 1 key feature: fixed filter frequency control! I performed a quick circuit bend to make the joystick/modwheel mounted filter input more fine-adjustable with a simple rotary control.
