Thanks for the kind words! Nimbus was a really fun project, just spent a bit re-formatting previous writeups to be more modern-web compliant. The one-wheel was indeed a weirdly synchronous release, I had no idea it would be as wildly succe

This paper was submitted march 2015, have there been subsequent studies in the last decade?

It does indeed work! I've been meaning to instrument a food stimulant mass to determine how the chaos is effected my mass offset vs speed. I think due to the under-actuated nature of the system you're stuck with a balance between

Admittedly this is a play on words, fair point! Gimbaled Gyro Sandwiches would be a better title

Have you noticed that a gyro sandwich is only cooked in one axis? I built a contraption to slow cook in multiple axes and documented it here: https://transistor-man.com/gyroscopic_gyros.html Not only is it tasty, it's

I'm interested, is there a hands on video or review somewhere? I can't get their timeline page to load correctly: https://furilabs.com/timeline/

It's always nice to see a detailed write up, a lot of cnc mill repairs end up replacing the existing control hardware but this write up was a curious take on maintaining the existing electronics, which takes more talent than replacing.

This is an excellent writeup, it's refreshing to see detailed writeups that are quick to load

What's remarkable is this quote comes from a book written in the 1920's

Thanks for the question, I completely missed that part. I'm using a homemade e-bike where the battery is just connected with a standard Anderson connector. A lot of off the shelf battery modules do have proprietary connectors, but a fa

This is excellent, wait does this actually work

Woah that comment is a call back, thanks for digging it up. I think one of the major boundary conditions, aside from 25V caps are just thermal. Laptops can't really radiate more than 100W continuously, and 20V at 5A is a fairly happy b

There's definitely ways to shrink this down and I tried to address that in the initial DC-DC selection. The minimum supply that certain P-Series Lenovos require is 135W, while this module is rated for 150W, it is available surplus for

That is so refreshing, yeah the lenovo P series just ignores USB-PD inputs as it nominally wants 135W external power minimum. The kicker is it rarely ever draws more than 90w

I really enjoy working remotely, like properly out in the woods. For whatever reason most of the 'desktop replacement' laptops refuse to use external USB-PD battery banks so I designed a quick in-line adapter around an industrial
