So... you want this to make an LED turn on for 10 seconds, then off?

I don't know exactly... I would ask around on the site. You could always go to my store... Shameless Plug.
But I would look other places too. Maybe try the Help section of the forums?

You should probably use a low powered 555 timer. This is a good link to learn about 555 timers. For a quicker solution though...
This instructable has a great 555 circuit. Just ignore the stuff about the painted circuit and just look at their schematic.
