Compadre 3D/coin check mod

[Electricfrontporch]

It's been raining for two days so I had some time to get this done.
Basically added two extra disc circuits with a three position toggle.
Sp3t toggle and 100k 25 turn Bourns trimmer pots.
Center position is the normal disc control.
Toggle down is set to break up on a nickel.
Toggle up discs out tabs, just barely accepting a zinc.
Will do some fine tuning and testing in the test bed when it quits drizzling.
I'm usually a dig it all guy so this will mostly be for a quick ID before digging.
Definitely was a good feeling to button it up and have it all still working,
and not lose any air test performance.
Hopefully it's still good in the dirt...lol

How did you know what to do? Sounds interesting.

Schematic was posted on another forum.
Search for Tesoro3D and you should be able to find it.
Relatively safe mod as it doesn't require any soldering on the circuit board, just on the potentiometers.
