Now I have to patiently wait for them to ship. I’m not shy about the Sweep inspiration.
The goal is to have it be modular, with a central controller board. I’m going to eventually use these with paracord cables to hot-plug different types of keyboards (the first will most likely be a gaming keyboard on the left). I’m looking for less bulky magnetic connectors if anyone knows a source. Definitely not considering a TRRS, as I don’t think my GPIOs should be mainlining 5V during hotplugging.
The controller is still being prototyped on a breadboard. I have already experienced the woes of hot-plugging I2C on the prototype boards (stuck bus and all), so I’m going to experiment with the TCA4307.
The firmware is being developed in Rust, though haven’t pushed it anywhere yet.
It’s 99% the thumb cluster: I wanted an extra button.
Also 99% for fun.
