Prototype

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.

Prototype front panel vision

Working prototype with extra features like "Sync 1-2 echo time" or "Set Midi all".

Also LCD screen inform us about last values of time/note for Echo 1 & 2.

Back panel

Back side with DIP 4-channel switch to choose MIDI channel. Power switch on the right side.

Mounting inside box

Soldering & testing process

Stress memory test on Arduino Uno R3 - which fails, so then I needed Arduino Mega to handle that.
