Knight Rider Scanner...


I am looking into making a Knight Rider-like scanner (see: K.I.T.T) consisting of a row of LEDs (perhaps about 20-30 or so) and was wondering if anyone knew if this circuit would work. I'm not sure if it goes back and forth and has a fade 'tail' or not...


I am looking to make the LEDs light up back and forth with a bit of a fade afterward so it looks like a smooth motion.

I am wanting to mount the 'scanner' onto a pair of sunglasses (don't ask, long story, lol). I would like to make the circuitry as small/minimal as possible to conceal in a small area such as behind one of the side frames.

Thanks for your time and help.

I don't think it does the fading at the ends, but ... it could. (Just a small matter of programming!)

Appreciate the quick and informative replies, both really helped. What are some nice end-all websites for buying little electronic parts such as gates/counters to be used in a project like these? The local Radioshack doesn't have any counters, surprisingly.

you want a larson scannar, um that's all I know on the subject, lol
