SPRKPLG x IDENTIDEM.design MRBPz Prototype | Mamiya RB Polaroid Back

Your chance to own a prototype based on the amazing MRBPz back by SPRKPLG with some slight improvements by myself. It's fully working and has been tested.

The difference between this back, and the standard MRBPz:

• Uses an ESP32-C6 microcontroller instead of the RP2040
• Runs custom firmware written in C++ instead of Circuitpython / Micropython
• A custom PCB that simplifies things a little because the  ESP32-C6 board I'm using has an accurate built-in battery gauge.
  

Some cool features:

• Film cartridge detection
• Film counter automatically resets when inserting a new cartridge
• Keep count of how many shots you have left
• Accurate battery life indicator

I will include a user manual, but using it is very simple! Simply turn on the back, insert a new film cartridge, press the button once to eject the darkslide, and you're good to go!

Because this is a prototype, I am selling it as is. It is fully working and constructed to a high standard. If something does go wrong, I'm happy to assist you in repairing it if possible.
