Amazingly my Dirtypcbs.com order has apparently shipped already, so hopefully with the DHL shipping it will be here by Friday. My OSHPARK order was upgraded to expidited processing for free, and is at the board house. No ship notice from Digikey, although I ordered late Friday night. I'll have to experiment later with different thermistors, as I apparently picked the most expensive ones. I think the same board could be used with cheaper NTC thermistors, but some of those I looked at had much wider resistance ranges, good for measuring, but I need more information on how easy the devices are to heat up. I haven't sat down and tried to understand if I can calculate a temp based on power and dissipation. So experimental methods will be used. One thing I forgot about was the compas but I might have one of those laying about.
