I took this class with D. in 2019! Was a great whirlwind through digital fab and microcontrollers.

ah this is fascinating!!!! Any more info anywhere?

For this in 2D, see Sam's thesis, 6.3.3 (p. 86, CNC wire plotting). 3D would add a lot of challenges. https://cba.mit.edu/docs/theses/19.09.calisch.pdf

Let me know how it goes!!

Knex is great! I had a small set growing up, but never one of the big dynamic ones. Did you ever come across Capsela? Another fun modular building kit. The floaty set was awesome.

Struts, nodes, and pins are reversibly assembled into fully 3D printed lattices, trusses, and tree-like structures spanning up to a few meters. I used the system to build a stand f…

If you run an X220 or X230 and do embedded development, build in an ARM debugger (a thing I made some years ago)! [1] [1] https://hackaday.io/project/27272-tp-bmp

Just install an NSA-B-GONE, my janky open-source modboard that adds Thinklight-controlled USB hardware switches to the webcam and microphone! Designed for the X220, but the X230 is…

Yeah, vias in particular are a challenge. I've spent time with annoying tiny copper rivets and bits of wire and the rest, and usually end up making one layer boards with perhaps a …

It's probably not excellent; the grooves are V-shaped and the machine isn't stiff enough to go very deep, so you'd need to take a lot of passes. But a crosshatch toolpath might pul…

I designed and fabricated a weird 3D printed 4-axis CNC machine (in ~3 months, oof) which uses carbide inserts to carve tiny isolation routes in chunks of PCB substrate. It's very …

We can, using big autoclaves and a process called hydrothermal synthesis. It's how we make single crystals that get sliced and diced into quartz oscillators. But the process takes …

Easy to learn, difficult to master. Great game, needs more levels.
