Anyone has issues with VT1 peltier FET? Grim said he destroyed a few but of course he didn't say what sort of current he was passing. Current VT1 is marginal in specs in any-case.
Looking at using IRF7832 in S08 package as the specs at Vgs ~3~3.3V (gate signal from ATMEga328) is at this level. Doing drawings up for this change now, have to put it on base of PCB but that's not an issue with it's higher current paths.
