If you arent in a rush, hold onto it until I get this worked out. The brownout wouldnt be hard to do at all. I just break the circuit at the 9v battery and then measure the current drawn by the circuit, use good ol' ohm's law to find the right pot value to brown out the circuit. Shouldnt be hard at all to do that. I can mount the potentiometer on the panel just like a volume knob, or I can do it internally so the value doesnt change on you. I think externally would be cool.
Have you tried shaving it?
