Voltage for the MiniPOV3
The kit ships with a clip for two AA batteries. Is it ok to run it off of another 3.3V source? In other words, will the extra 0.3V make that much of a difference? I know battery tolerances aren't perfect.

from http://www.ladyada.net/make/minipov3/hardware.html:
Batteries
The MiniPOV2 kit comes with a 2xAA battery case. The resistor values were chosen with the expectation that you'll use alkalines, but rechargables should be OK too. In fact, any high-capacity 2.5 to 5VDC supply can be used (but certainly not a 9V!). Of course, if the voltage goes up, the choke resistors for the LED have to be larger to keep the same brightness.
When programming, I suggest making sure you're using fresh batteries, preferrably alkalines. Sometimes the MiniPOV can act flakey if the batteries are low.
