Well it looks like you're using the twiddler out of spec.
3 AA batteries give about 4.8 to 5 Volts when full, but the voltage drops
when you use them for a while. Since the twiddler requires 5 Volts, strange
things may happen, so I'm not very surprised... ;)

Solution : use a 5 Volt power supply for the twiddler.

Plan A : IMHO a DC/DC converter gives the best results. Input may go as low
as 3 Volts, while the output remains a rock solid 5 V. You'd only need a
small one.

Plan B : Or use a 9 V battery, and a 5V regulator. It's a bit cheaper, but
you're wasting a lot of power this way, so you'll end up buying a lot of
batteries.
