I've been fighting this issue for a while now. I've tried some bandaids to deal
with it, tried multiple repeater controllers (including one I designed myself
with an ATMEGA328 Microcontroller (I'll probably be releasing this design as
open source coming up)... and I'm fighting the same problem e
Hi Josh,
Instead of resistors, try diodes in series. Each Diode will drop your
voltage. I have series a couple to get rid of standing voltage, especially
if you are down to a half volt or so.
