So after a bit of a hiatus I’m back working on this project. I completed the V3 hardware some time ago and recently I’ve made quite a bit of progress on the software.
Hardware Details
Here’s some pictures of the V3 prototype as well as the schematic
Observations on the Hardware Design
The thumb joystick for pitch selection is a definite fail. There isn’t enough travel to give accurate control over pitch. For V4 I need to find away to provide about 40-50mm of travel for pitch control. For now I’m going to resist the urge to take this prototype apart and build a new one and focus on software. When I do build a new one I’m going to use MX style keyboard switches for the valves. I just bought some silent ones and they are very smooth and easy to press but also robust.
