How did they ever decode DTMF before Fourier transforms? Checkmate atheists!
Did anyone ever build a clone of this around a Raspberry Pi?

Stay in to get a good night's rest on NYE. Wake up every 30 minutes. Feel like death. Drive to the office. It's a holiday. FML
For $2800 you can get a half-decent automatic pick-and-place, but this manual one is still way badass, and I would be tempted to go for it instead.
The most tedious bit about doing PCB assembly by hand is unpackaging and organizing components before you begin
This one is gonna take two full project trays which are super helpful but if you knock it over you might as well just order a whole new BOM from your vendor
This is awesome. Makes me want to finish repairing my Mac SE/30

The best Atari 2600-compatible joystick ever produced
3D-printed PCB through-hole assembly jigging for holding parts in place while a board is upside-down for soldering.
I was asked to give a talk or run a workshop at WOPR Summit about lessons I've learned manufacturing homebrew electronics at (modest) scale. I wasn't able to make that commitment in time, but I will be writing up some blog posts in lieu of a presentation.
For my Casio SK-1 brain, I'm thinking about automating it more by taking in the audio (It's only ~10kHz IIRC), using some fast Fourier transform library, and implementing a basic genetic algorithm to help generate and evolve ROM data that causes complex sounds to play. Fuzzing!
When I'm making a symbol for a connector to run a bunch of signals between two boards, I've started blocking off the pins logically and it's surprisingly helpful.

installed a package with npm today.. it went like this
first npm warned about 2 known security holes in libraries, but installed them anyway. One was a 2017 code execution vulnerability in some kind of eval library, fixed in a newer version but the dependency had not been updated. Yikes.
Then npm crashed. I restarted it.
Then a package used a postinstall script to display an advertisement.
Then a package used a postinstall script to download a binary blob.

A deterministic hardware 27C256 fuzzer, designed to (initially) drop in to replace the ROM in the Casio SK-1 to generate weird noises.
