Viewer Challenge- Larson Scanner

hunter1919hunter over 15 years ago

I would like to build a larson scanner like the one in Kight Rider. Im thying to build one like http://www.thinkgeek.com/geektoys/science/cca8/?cpg=froogle. Im trying to put it in my car and come on when the car is on. The link scanner is built with a switch and that will not work.

I would like to use 5mm or 10mm red leds
I could not use an arduino
a main switch on the dach to turn off when not in use when driving

Thanks,

Hunter

NE555 should do the trick, yeah. Then again I'm the one trying to do it totally old school using nothing more complex than transistors and other basic componants.The only reason to use an Arduino on this is that it has better fade out effects for the LEDs. That and the fact that they don't need as many rectifiers.
