2023-05-19 (F) Weekly Summary

I redesigned my project to use machine screws instead of wood screws. I made slots with a cavity to hold a nut and cut twelve discs. Trimming was done with a razor and drill, and I made six units.
Retainer discs

I made blade templates from plywood to replace the worn aluminum tape. I traced the template with a scalpel and cleaned up the corners with scissors. I drilled holes for the caps but had to cut some twice because I misjudged their location. All repairs are done, and the knives are ready for use.
Refurbished electric knives

I bought a wireless keyboard for Rock Band on Xbox 360 to hack into a macro keyboard or MIDI synthesizer. I bought a wireless adapter for my laptop, but connecting it was challenging. I had to force my laptop to use Microsoft's drivers. The key presses simultaneously appear as an analog joystick value and one bit on another axis.
Keyboard visualizer

Instead of using a gamepad-to-macro approach, I focused on converting MIDI DIN instruments into macro keyboards. A wearable keytar is ideal since it can perform common tasks even while walking. I plan to build a controller that accepts old-school MIDI signals and transmits Bluetooth HID commands. The controller will have a key for each macro, making it easy to use. I chose an ESP32 experimenter with an onboard OLED screen and battery charging circuitry, but I had some issues with the UART pins.
MIDI proof

I used a wireless MIDI device to trigger computer macros with a keytar. I also used speech-to-text activated the same way and got ideas for future projects.

I made tricked Zener cards using magnets and plywood, but they didn't feel natural. If I wanted to see this project through, I think the best solution would be to create resin tiles, like dominos, with magnets cast into the product.
