I built myself a little adjustable bench power supply from Chinese modules, partly because I thought it would be handy to have one, and mostly because I wanted a small, straightforward project to do for my own sanity. I set … Continue reading
I hacked together an Arduino Micro firmware that is a drop-in replacement for a Spiffchorder, long version and code below the fold.
A second consecutive CNC post, because I haven’t had time to write up long-form posts for months, and something requiring documentation came up today. While I’m still quite happy with LinuxCNC (especially since I discovered NativeCAM), my adviser bought himself … Continue reading
I’ve been fascinated with machine tools and mechatronics for well over a decade, and have been indulging that fascination with a series of little benchtop CNC machines since about 2008, especially since my collection of related degrees lend legitimacy to … Continue reading
The lab Makergear M2’s heated bed power supply died a few weeks ago, so we decided it was time for a serious upgrade, and set out to equip it with basically the best parts currently on the market, as we’re … Continue reading
I’ve done some invasive repairs on the Macintosh LC from my small fleet of vintage computers. I figure it’s worth writing up because there is a lack of detailed information about this kind of work on the ‘net.

My 5-year-old T510 has been showing its age, mostly by falling apart (speakers died, parts held on with gaffers tape, occasional probably-thermal GPU lockups, etc.) and I decided it was time for a replacement. Unfortunately, the laptop market right now … Continue reading
