[Biohackers] PCR

so people are kinda diggin these things: http://www.reddit.com/r/AskReddit/comments/1jxy39/tech_savvy_folks_of_reddi… Do y'all have a schematic in mind, maybe with an associated attachment or URL nudge nudge wink wink? Also, I dropped off my tub of thermal grease in the PCR styrobox. Be very careful not to get it on non-expendable clothes! I know a peltier element is involved - I've done one experiment that faled due to insufficient heat sink/fan action, but it was a tiny fan. Eager to get the driver software/hardware figured out for simple temp control but won't have time to work on it until end of sept. cheers, hol
