Further to the sensor dew heater in the previous post, the newly installed Tellurex 25x12x3.4mm TEC fits comfortably inside the space available with a very tight fit, using 1mm sheet for the copper finger, fixed to the camera chassis with 5lb external quality wall mounting double sided tape - the black and red roll found at hardware stores.
The Tellurex module though smaller, is speedy. Much faster than the standard ebay TECs. And marginally better differential at 9C @ 2.6V, without an external module to help it along - still not the magic 10 - 12.
Tellurex is ~16US, but international freight, which appears to be non-negotiable, is ridiculously high. I made other arrangements to keep the costs low.
Hope to complete assembly tonight. New moon is not far away, but forecast is rain.
A word on DC DC converters. I learned the hard way... first calculate power requirements, voltage x amps and double that to get the converter rating.
