Hi Milton,

Here`s another link from the thread about a cooler for a Canon Digital Rebel, DSLR

http://ghonis2.ho8.com/rebelmod450d16d.html

..I wonder if you`ve seen this one or if it`s any use to you..?

Milton, 

Here`s the other link I have for him;

I can`t see anything about the Peltier cooler in equipment though..

so apart from contacting him by email I don`t know how you`d find out..

There`s been a bit of a discussion about Peltier`s on the IP group..

Here`s a page Shevill Mathers from Tasmania has posted about making a Peltier for a Mintron video camera back before the days of DSLR`s..

I saw the Mintron link before.

If one wants to spend $100+ USD, one can go to those big heavy (up to 1 kilo) copper heat pipe based CPU sinks that they use in the higher end CPUs and GPUs. Some have all the necessary stuff for water cooling too.

My next cooling mod will likely be invasive and involve a cold (copper) finger inside the Grasshopper Camera around the CCD.

TTYL..

Thanks for the link.

I wish he had posted details on the Peltier cooler model he used, how much power / amps he's inputting and some other details.

TTYL..
