I'm just taking the plunge and performing these mods on my ToUcam as described on Ash's Astro Pages:

It's a two-step process whereby I've firstly removed the CCD array from the camera's circuit board and will attach it to a heat-sunk and fanned peltier device. I've chosen a 30watt unit which should draw around 4 amps when running. Eek! Big battery required. Second phase will be to carry out the long exposure mod. I plan to re-case the whole shebang in a new plastic waterproof case.
First I've removed the CCD array. Applying quick heat to the pins and a sharp knife I was able to gently pry up each leg and straighten it.
Holding it gingerly in a clamp edge-on, I attached 7-core ribbon to each side so that it can then connect back to the board remotely - allowing me to locate the CCD where the back of it can be cooled - on the peltier device.
