girl who has NO respect for her linear regulator circuit 😭

towards the end of a project I like to take a step back and look more at this like a nest of wires to untangle. during layout you look to find any connection you can. once 100% routed you can begin to clean it all up ✨ I'm stoned and vibin with good music and its chill work 🐶

Can anyone familiar with switch mode power supplies comment on this layout? I always forget the advice I have been given and just kinda do them based on vibes, prob rely too much on fat traces. Plz repost. 💜🙏 Also I am using @thea.codes' lovely Witch Hazel theme for Kicad. ⚡

My board is designed to go with my Raspberry Pi compute module motherboard so you can have a 60V DC power circuit that runs all your motors and central coordination via a dedicated CAN bus circuit. You can even update motor controller firmware over CAN bus. github.com/sequoia-hope...

Made some updates to the USB-C PD circuit and pushed to github. You can view the board in this web viewer [1]. I also remembered I made this smaller than a credit card or a business card! I could use this as a cool circuit board business card. ⚡

I got a second needle bed for my 1990’s knitting machine that I’ve modded with #ayab (all yarns are beautiful) www.ayab-knitting.com

I have made great progress on my RP2350 powered open source brushless motor (and industrial stepper) controller! This board supports up to 53v max, 30+A peak (depends on thermals), and is designed so anyone can order them from JLCPCB. I also just added USB-PD for 100W at 20V via USB-C!

Apple has activated Sequoia’s ✨special interest✨

I’m literally making a bag right now with a very similar design to Apple’s lol. See also my comment on hacker news about the 3D knitting aspect of it. 🧶

The Hiatchi in question, because dudes love to do home construction while they talk about sports.

I thought I would share a comment I left on Not Just Bikes’ video on John Forester’s book Effective Cycling. Forester rides like I do, borne of athletic cycling in car infested wastelands, but totally fails to see how unacceptable this is as public transit. People deserve better than this.

Yaaaa I realized I can interweave the dyneema with something which has more body like this pink cotton. This is much more usable as a material! It was too thin otherwise, though the pure dyneema could work as a liner for internal bag pockets.

I got a haircut! Actually my first haircut in idk like ten years lmao

Okay I fixed the cam alignment issue caused by the yarn ball jam in the cam mechanism (my fault). However I had an issue in the 木 pattern with this ghosting problem. My machine might skip alignment when doing the checker background pattern. But I re-aligned it a second time. Let’s hope it holds. 🐶

Last couple days of knitting! I made a text to knitting pattern generator which I used in two of these. The other is a free pattern that was published by the machine manufacturer. I can do a lot! Now to plan projects… 😸🧶⚡️ #ayab #knitting

Haven’t posted a bike joint selfie in a while. I ran out of pre-rolls! 🐶
