Long story short: In Sept I left Twisted Fields, where I was designing Acorn the open source farming robot. I’ve found a new job at a fast paced startup. It’s really fun! I will maintain a fork of Acorn, and continue with my plan to stabilize the design and publish detailed docs.

I’m really proud of those handles tho. I know I am such a nerd about this but it feels so clean to me lmao.
Wow would you look at that there’s something for everyone! Butts and PCB designs??? Amazing stuff. Yeah yeah I finally have an alt I’m doin it she’s gotta come out she’s been hiding too long. ⚡️🍑✨

I actually typed this up on a typewriter and blacked it out with a sharpie. I still have the original on my wall. 😸.

Been workin on this 2.5 years. I am still going, tho slower now. I am working on an RP2350 version, with a fourth bridge so it can also drive industrial closed loop steppers. It has voltage sensing for sensorless brushless. It’s moving on hobby time now, but it’s coming.
Initial layout of my RP2040 brushless motor controller is completed. It can control 2 motors w/encoders at 45A continuous for each motor up to 60 volts. It's exactly the same size as a credit card, 100% open source, & designed for JLCPCB assembly service.

Dang they really do algorithmically suppress this. Sucks I can’t tell my friends where to find me. 🤬.
PLEASE LIKE AND RETWEET . I’m primarily posting on Bluesky now. It’s really taking off! I’m getting a steady stream of new followers by the day but I miss YOU! Come join and get in to it over at the new place. Also I’m way more feral over there. 😸.
