I have a small sketch running on a mini. Also runs on an UNO, which I have. I only need crude timing, and a couple of port pins (outputs), nothing else.

I'm trying to make it smaller, and use less power. Is there a way to move this to an 8pin Atmel chip? I do not have an Atmel development system...

Hi Mike,

You can very easily turn your Uno into a programmer for an Attiny. Here's an instructable for it: http://www.instructables.com/id/How-to-program-attiny-using-arduino-uno/

Or, if you prefer: http://highlowtech.org/?p=1706

The ATtiny45 and 85 are both 8-pin DIP devices that should suit your needs.

As for writing the actual code for them, perhaps this tutorial will be of use: http://highlowtech.org/?p=1695

Hope this helps!
Regards,
Matt
