Computer scientist, EDA and optimization. I build guitars from kits and write apps in my spare time.

I drilled out a section of the body to fit the push-button switch, and then made a channel to the main control cavity, so that I could run the wires. One wire goes to the pickup selector (ground), and the other is connected to the output wire. The pick guard was something that I got from Amazon for $20. Crazy. Triple hum buckers, each with the ability to coil split, and then there's also a push-on-push-off ground button.

Analytic placement results for a simple mesh structure; given an initial random arrangement of the vertices, simple interpolation moves everything back the proper grid. If you're reading this alt text... I've been working on circuit placement for a heck of a long time, and there's been a lot of interest in fully automated mixed size placement lately. I had a paper on this about 20 years ago, but I think I was ahead of my time. Seems like the time is now. The new tool combines a few different techniques. I needed a simple analytic placer as a subroutine, so I knocked it together quickly. On constructed test data, it's doing the right thing, so I'll assume it'll do the right thing on real circuits. I'm rewriting everything in Rust; makes a whole bunch of stuff easier. Really good programming language, the first meaningful step forward since K&R C. C++ and Java can go take a hike.
