I'm using this circuit here: **broken link removed** and **broken link removed** (The first is just a buffer, the second controls the lights.) I'm also using this circuit: **broken link removed** to generate the -12V
I'm running it in my car and I've had it in there for a couple months now, still on a breadboard. I'm going to solder it to a perf. board and put it in a project box sometime soon.
I was wondering if it is possible to convert the schematic so that I can use a single rail op amp. (LM324 to be exact). I was thinking of just using some resistors as a voltage divider.
The -12V would be connected to the car ground, and the gnd in the schematic would be in the middle of my voltage divider.
