Wow! Indeed it is. Quite impressive. A good way to get a cheap cooled one-shot colour cam too.

If you ask him nicely, I'm sure Mark would like to practice on a D3 before damaging a perfectly good 350D.
And Tony, well Tony would just like to practice on anything breakable ;)

Mick,

That's a brilliant find - well done!  It gives me lots of ideas for my 350D Peltier mod.

I like the way he disconnects ribbon cables to determine if they are important or not!

However, it seems a bit odd that he appears to have put the heatsink inside the aluminium box where it will warm everything up.  Or have I misunderstood this part (first image in section 4).

His particular Peltier chip consumes 3.7A at 12v - I would need a whole car battery just dedicated to cooling.

I hadn't noticed that, there doesn't even appear to be an airflow over the heat sink, just a fan trying to suck air out of a sealed container.
Although he has sealed the "camera" in a poly bag which might help a bit.
He has managed some impressive improvements for what looks like an inefficient design though.

Also regarding your coldfinger clearance issues between the CCD - are you aware that you can get copper shim in various thicknesses down to around .003"

That sounds interesting.  Where from?
