</div>Any chance of doing a project page on this? That could be cool.<br>

Even cooler (no pun intended) would be something with a termistor on a<br>
lead that could be stuffed into a hard drive caddy space. :-)<br>

--Yan</blockquote><div><br>Sure. I don't think the programming on this is difficult, and the data sheet practically gives you the basics. All that would be needed is to build the same circuit that Raphael posted except to use what's in the AVR datasheet instead of the MIC502. I would need to order some parts, but if I get a protoype working, I'll be sure and post it.<br>
