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.

@mferraro89 Amazing 😻

Is this a new one?

[Sequoia Alexander (moved to bsky @sequoia.farm) @TLAlexander]

@SadlyItsBradley Hey Brad I’m wondering about the Meganex 8k as a Valve Index upgrade. Looks like all the reviews right now are from shills. Thoughts??

I've been making excellent progress on my open source brushless motor controller with stepper motor and encoder support. The schematic is essentially complete and I got all parts roughly placed inside the board outline.

Check out the updated github page in the next tweet!

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

[Sequoia Alexander (moved to bsky @sequoia.farm) @TLAlexander]

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. ⚡️🍑✨

[Sequoia Alexander (moved to bsky @sequoia.farm) @TLAlexander]

Like I sort of have an alt on Twitter but it was never linked on main. It didn’t feel right to promote the farm robot and also post my ass and talk about getting railed. But it was hard keeping that in lol. I feel some sense of balance now that I have two equal linked accounts.

@ZubiSas Not interested in Altium (I do use it professionally at work) as this project needs to be supported by open source tools. But I did have some followers do sim for me before, I’ll check out PCB arts!

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.

[Sequoia Alexander (moved to bsky @sequoia.farm) @TLAlexander]

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.

@will_whang Omg new??? I missed having the one by the AMC back in the day.

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

@VisValley @JohnBauters Oh wow huh…. I swore I saw results showing his lead with 100% precincts reporting, but that was a hell of a week so maybe I just misread it. Gosh how silly of me. 😖

[Sequoia Alexander (moved to bsky @sequoia.farm) @TLAlexander]

Haha wow well would you look at that display name

[Sequoia Alexander (moved to bsky @sequoia.farm) @TLAlexander]

@BillieTheGoose Oooh good idea thanks!

[Sequoia Alexander (moved to bsky @sequoia.farm) @TLAlexander]

Dang they really do algorithmically suppress this. Sucks I can’t tell my friends where to find me. 🤬

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. 😸

@JohnBauters Congrats on the election John! I hope you can help make the whole county as livable and bikeable as Emeryville! My new job has me biking to work in Berkeley every day (yaaay!) and the Emeryville greenway is so lovely! 😸
