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.


September 2019 / Projects

I’ve completed a DIY project modding the Korg Monotron for analog CV input. I have found some other descriptions of similar mods online, but so far as I know I’m the first to document the build on video or provide PCB layouts, so while monotron hacks may be old hat, I think this brings something new to the table.

September 2019 / blog

I spent the month of August up in Sequim, WA, working on rebuilding Tally Ho, a century-old wooden racing yacht, with its owner Leo and a crew of other volunteers.

June 2019 / projects

I built a new studio desk based on the Platform Desk by Output. It has a monitor shelf, rack space for audio gear, and a sliding keyboard tray, with all plywood construction. I drafted the cutout plans in QCAD and then produced a tutorial video.

May 2018 / Projects

Super Sixteen is an open-source hardware sequencer for the Eurorack synthesizer format. I’m developing it on the Arduino platform and documenting my progress in a free video series.

August 2017 / Blog / Photos

In August 2017, I traveled to South Carolina to observe the total solar eclipse. I brought with me an old Celestron C90 spotting telescope and my camera to see what I could capture. I was very lucky, as we found a secluded lakeside location to view the event and were just able to see totality before clouds descended on us.
