Arduino Nano based, digital counter for a Revox B77 Reel-to-Reel with Rewind2Zero function.
Original idea & code from https://old-fidelity-forum.de/thread-38940.html Special thanks to DIYLAB-Bruno, User "Gogosch" and all that have participated - excellent work, Gentlemen!
Version 2.0 stable:
- Click on boot: total running hours
- Click to reset
- Turn to change from counter to meters to seconds (simple conversion - no true seconds)
- Hold to change brightness
- Pause indicator (needs Pause Memory PCB: eBay Mauro200id)
- Auto rewind to 0 on double click (needs relais module)
- 3D files for relais bracket, main board distance bracket and IR Sensor clips are included
Hardware needed:
- 2 HW-006 V1.3 Line Tracker Sensor Modules
- 4 white markers on right spooling motor
- 1 EC12 RE1 360 Degree Rotary Encocer with push button
- 1 0.91 inch OLED module white 128X32
1 Mini DC-DC 12-24V To 5V 3A Step Down Power Supply Module(edit: unfortunately this causes a very low disturbing noise)- 1 Mini 230V AC to 5V DC 2A power supply (to get clean discrete power for your arduino & acessories)
- 1 Relay module 2 Channel 5V 12V Relay Module Board Shield with Optocoupler Support High and Low Level Trigger for Arduino
