2023-10-27 (F) Weekly Summary

I tested a circuit to show off Phlute. It only used a DTMF decoder and microphone module. Without a microcontroller, it demonstrates the simplicity of the hardware better than I could do with software.
Testing Phlute

I sketched my circuit, replaced the USB power supply with a 6-volt AA battery pack, added 1KΩ resistors between the decoder module and LEDs, and assembled everything on a prototyping PCB. The chip was not as accurate as the app, but it was responsive enough.
(0:02) Test with soldered circuit

I restarted the EWC_Cyberdeck project, and I will tackle the portion responsible for MIDI generation next. This section will match the keyboard's color scheme but will have much different hardware. I gathered my buttons, encoders, and the like and created a CAD layout.
EWC_Cyberdeck MIDI section

I made a few more tweaks to the faceplate and cut a plywood copy with my laser engraver. I made more changes to fix some minor mistakes, cut another one, and mounted the hardware to ensure a good fit. I will have to remove everything to paint it.
Test fit of all the operators

I fixed my EWC_Box by changing the screen orientation in the drawing and cutting a new faceplate. I painted it yellow and black, then moved the components from the old faceplate and tightened the nuts with a wrench.
This is how it will look

I installed eight encoders, but they still need soldering. Trimmed the nylon coupling nuts and created an IO list to guide me when I start soldering or drafting.
Connections for the MIDI section
