I demonstrate the completed heating / cooling calibration oven which is now powered from my solar panel. The output cools just like an aircon...!

As per viewer input and advice I reversed the polarity on the peltier element (Thermoelectric effect - http://en.wikipedia.org/wiki/Thermoelectric_effect) and created a brilliant heating effect on the 12 volt electric cooler box! Thanks!
I also show the SMD (surface mount devices) to DIP (dual inline package) adapter which I will be using for some of the voltage references I have. I will post a video of my first attempt to solder the SMD IC's to these adapters.. a novice "SMD solderer".
