Hi there! Really interesting project here, but, can I ask you about how is it powered? Thanks, and again, really sweet project
Thanks! It runs on a rechargeable 5v battery, so I just ripped that out and tapped a power supply from the 5v in the Gameboy.
Isn't the gameboy 6V? And I was thinking, how have you wired the select button to the bluetooth button?
The batteries add up to 6v but in terms of tapping into power from the regulator is 5v. I've just scraped the traces on the front of the PCB for the select button. It shares a ground with the up on the d pad so I ended up using a diode to keep that working too. After some testing with LSDJ I do occasionally switch on the bluetooth by accident. I'll use a separate switch next time.
