Prototype 6.1 - Recording Module Hack

We can now control the 'play' function of the RadioShack recording module. There was a simple piezo-type switch on the board, so we just traced the foil circuitry back to a point where we could solder two leads. We now have a switch that we can control with a relay from the Arduino. We tested that wiring using a simple on/off program before soldering. There's also a 'record' switch that is set up in a similar way, so we may wire into that too.

The green wires at the bottom of the photo are our new leads:


Possible input/output logic could be:
Put your hand 24-12" away, we record you.
Move your hand <12" away, we play back what we recorded.

This could be a self-contained device, run off of 9V batteries and mounted to the wall, but it could also be put on the street or in an unexpected location.
