Great to hear that the parts finally arrived. Australia Post express took "only" Thursday -> Monday to deliver. I though they were delivering parcels on the weekends during the Christmas period?
I ran my partial Cam86 with a 9V power supply. 3.3V regulator runs at about 60C while 5.5V regulator runs at about 50C. The 6V? regulator is at about 40C. I am not sure if using 6V to feed the 3.3V regulator would work as it may just overheat the 6V regulator.
Also found some 7.5V power supplies
here. May not be enough power for the TEC.
Someone correct me if I am wrong but I could not find the old posts, is the minimum voltage to run Cam86 7.2V?
