Guest StevenWhatley Posted August 10, 2015 Share Posted August 10, 2015 I have fancied ago at building one of these for a while so finally took the plunge.. I ordered all the bits of eBay (I'm still waiting for the Thermometer & Control unit to arrive) So I built the Peltier Cooler by using 2x Heat Sinks / x1 Peltier Plate Module / 2x Fans running at 12v / 5amps Any how here is Version 1 DSLR Cool Box V1 by Steven Whatley, on Flickr DSLR Cool Box V1 by Steven Whatley, on Flickr Version 2 - Just a slightly smaller box and a little tidied with the construction.. Next I need to add the insulation.

+RonC Posted August 10, 2015 Share Posted August 10, 2015 Seems a bit OTT to me Steve? I added a double battery box that leaves the battery compartment empty and much cooler, had no problems so far! I'll check it out at Anderby ! Link to comment Share on other sites More sharing options...
Guest StevenWhatley Posted August 10, 2015 Share Posted August 10, 2015 Yeah it probably is OTT Ron but I like to tinker lol !! Link to comment Share on other sites More sharing options...
Doc Posted August 10, 2015 Share Posted August 10, 2015 Does this all hang of your focuser, if so maybe a tad OTT. Link to comment Share on other sites More sharing options...
stash Posted August 10, 2015 Share Posted August 10, 2015 They may laugh now but they won't when you appear on Dragons Den - remember the one who didn't scorn as i will be still saving for my 20 inch (telescope !) by then Link to comment Share on other sites More sharing options...
+Graham Posted August 10, 2015 Share Posted August 10, 2015 Interesting idea Sorry Steven but I cannot see the advantage. Without the peltier touching the camera's chip I cannot see what you are going to gain. As most of your imaging will be done on cold dark winter nights the cool box becomes obsolete as the ambient temp will be lower than that inside the box. The ones I have machined up for people in the past pass through the camera body and rest against the chip. This method makes a huge difference.

StuartJPP Posted August 10, 2015 Share Posted August 10, 2015 The acid test will be to see what the temperature gets up to after say 1 hour of imaging with cooling turned off and then after an hour with cooling on. The temperature is embedded in the EXIF file. Link to comment Share on other sites More sharing options...
xanthic Posted August 11, 2015 Share Posted August 11, 2015 It'd be well worth getting an external PSU for the camera. The battery is a source of heat as it works and as you approach -20 degrees, lithium cells perform very badly. Link to comment Share on other sites More sharing options...
BAZ Posted August 11, 2015 Share Posted August 11, 2015 I would keep an eye open for condensation forming, it does this readily in my cool box and even with kitchen paper in the bottom there is still a lot of liquid water. I would hate to see your camera ruined. Link to comment Share on other sites More sharing options...
+Bino-viewer Posted August 22, 2015 Share Posted August 22, 2015 As a matter of general interest, would putting the camera in your fridge (minus battery, lens) have the same (any) effect ?? Would it make any difference for me ? I'm shortly about to start some wide-angle imaging once my new lens arrives. I'm planning stacking multiple 30 sec images using a wide angle lens and very high ISO's. Sorry if i'm hijacking the thread. Thanks. Link to comment Share on other sites More sharing options...
