Question:

I do not have an oscilloscope. sigh....

Google said that the USB spec rated Vcc at 5 volts. The PICkit 2 printed circuits indicates its Vcc as coming straight from the Microchip PICkit USB interface. It goes directly into the PIC itself. Is there a voltage regulator inside that plastic case? If not the PIC16F887 is seeing 5volts?

On the subject of rechargeable batteries the RC hobby cars gobble through their Ni-Ca drive wheel charges at an awesome rate. I was hoping that the PIC batteries would pretty much last an afternoon. Wouldn't four AA alkaline non-rechargeable batteries be the easiest to deal with? Just put a new bunch in at the start of the day.
