2023-03-12 (Su) EWC_Box Internal connections

I increased the percussion note rate to 4x the BPM, and it sounded the same as my drum machine since the programming was similar, and that was my goal. I wrote a list of the programming changes I wanted but derailed myself and set to work getting the internals up to date.

I intended to install a large-capacity RC battery in the enclosure. Unfortunately, I forgot to buy industrial Velcro for mounting, so I installed a cordless tool battery adapter in the upper left corner. I was not too fond of the idea of Velcro anyway. I added some USB ports in the lower left to power a Bluetooth transmitter and any other 5V devices I want in the future.

The ever-expanding need for power hit a limit, and I stopped daisy-chaining wires with solder and doubling up at screw terminals. I installed a power strip with a comb jumper at the bottom where I could tap off power coming from the "Amplifier" switch.

All of the internals are functional. I can put the back cover on, power up the amplifier and controller circuits, and it will make music. I can carry it like a boombox, so the construction phase is done, barring any improvements or fixes.
Messy but functional
