A PIC is total overkill guys (IMO... no flaming, please).

Try this. (Scroll down about half-way to "LED Chasers".)

Perhaps that will work. I'm going to bed, in the morning if nothing's simpler I'll try to get those free chips!

*points to my previous post* You posted while I was editing. I posted a different page. It's even easier.

that isn't my auction, but i have a bunch of those in red. they run off 12v and have a button to switch modes. it needs a live 12v source to remember the last setting though..

That one looks very simple. Thanks E-Rain!

...but where can I get a 4017 timer? All the TI decade counters are ones you must pay for, and the rest are obsolete on there.

welcome to the real world kurt, where nothings actually free.

the reason I keep saying use a PIC is cause THERES ALREADY ONE DOWNSTAIRS.

honestly if Im bored today Ill just do it for you.

oh btw, we also have a voltage-controlled-oscillator on a chip and a decade counter somewhere. we got them when ryan went to venture camp two summers ago and made the exact same thing. i think i know where they are too.
