I wouldn't mind using this because it uses much fewer parts, but i know next to nothing about this PIC, much less on how to program one it and with what...
You could follow the schematic and program (blinky) in the back of the Junebug manual. It uses only 3 I/O pins to run 6 LEDs charlieplexed **broken link removed**
The original KITT Knight Rider used incandescent light bulbs that took time to brighten and turn off so they faded between each other.
LEDs immediately turn on and turn off and don't fade. They just jerk on and jerk off abruptly.
Maybe big capacitors can be used in parallel with the LEDs to fade them on and off.
Audioguru that information really usefull I was thinking how the original Knight Rider fades the bulbs.Now I got the point they were using incandescent light bulbs.
Anyway I like to share my designs done with cheapy LED's.

I used the junbug to teach my kids how to run charlie plexed displays. The night rider effect was one the the project we did. In the next lesson they learned to use polled timers in place of delays. When we do interrups in a few weeks it will be used for that as well.

Very nice... i'd like to start programming my own PICs sometime soon. So many programers to choose from out there, not sure which to use as a first time hobbyist.
I've knoticed that all PIC projects need +5v to operate. I just have to wonder why they weren't built to handle higher voltages... or are they just another logic circuit?
A simple LM7805 is a popular way to reduce and regulate to 5V. There are a couple of HV PICs that have a built in regulator but these are not very common and the I/O is still 5V.
I am not very knowledgeable about electronics but am amazed by the simplicity of your Knight Rider circuit. I have been wanting to incorporate the scanner into a project vehicle that I'm working on. Would you consider selling me a programed PIC 16F628A? Please let me know. Thanks...
The Velleman K8048 is a JDM type programmer with a demo board. A PICkit2 or my Junebug kit are about the same price as the K8048 and both are USB based with MPLAB support and program most Flash based PICs.
Stay away from the mind dead programers that do not work with MPLAB. All JDM units included.
Get a PIC based unit that had MPLAB support for debugging.
EDIT: At times I sound like a salesmen for Junebugs. Prior to getting one I did not have a clue how much better
they were the a serial ICD2 clone which is way better then a JDM type. It is a great kit. I have 5 of them.
