well shit... i tried to hook up an op amp (its rails are powered from the arduino) instead of the diode and same story.. when i hook the output from the low pass filter into the opamp, the sine goes flat
the op amp is connected in a simple voltage repeater mode, where it just copies the top half of the sine wave to the output, so where in the name of fuck is the damn problem?
