Here’s an upgrade of my previous TEC-cooled 450D project. It uses a cold copper plate mounted directly at the back of the imaging sensor, which is then cooled by a stack of 2 Peltiers, one being more powerful than the other (40 mm and 30 mm modules). Non-electrically conductive thermal paste (Zalman) has been used to promote effective heat transfer and yet avoid electrical hazard.  A12V 12A DC adapter powers the fan, Peltiers, and the heater.  A standard Canon adapter powers the camera.

    • Thanks Shevill,
      Your modification with a 350D is really amazing, particularly your design of an airtight chamber :) I look forward to seeing more of your modification projects/designs applied to recent camera models. :)
