    Basic training. ALL dc relays need a clamping diode (reverse polarity) as close to the coil as possable. Electronics don't like voltage spikes.

    You are welcome bucketmouse. Keep the brownout routine in you program. Once you get the servos moving back and forth I think that 9 volt will be inadequate.

    you will need to change you power supply. the 9v battery doesn't have the power to run all 4 power hungry devices. if you put the servos +v and a transistor on the relay and then connent them to a separate 4AA battery pack it will work fine.
