- Box preparation
I turned dreams into reality. No one produces such a machine, so I made it myself from scratch.
After 4 months of soldering, programming, drilling - working prototype is done.
This machine is built based on Arduino Mega 2560, a lot of expanders and AD converters.
Photos of last final steps are listed below.
Also LCD screen inform us about last values of time/note for Echo 1 & 2.
Back side with DIP 4-channel switch to choose MIDI channel. Power switch on the right side.
Stress memory test on Arduino Uno R3 - which fails, so then I needed Arduino Mega to handle that.
