Just a note to the next guy, you don't absolutely have to have 5V to operate a lot of these PICs.

For example, on a 16F628, check the DC Characteristics in section 17.1 of the datasheet and look at VDD supply voltage.
- it runs fine from 3.0 - 5.5 V, just keep an eye out on Brown-out Detect Voltage if you're using that feature.

Just don't fixate on the Absolute Maximum Ratings in section 17.0 (like I was doing).
- 6.5 V max on VDD.
- 14V max on MCLR.

If you run a bit lower than the "normal" 5 volts, you might have to adjust the resistors a bit for things like LEDs.
