I am a big fan of Ben Heck. Way back in 2011, Ben made a Super Can Cooler on his YouTube channel and I'd always thought it was a neat idea, something I'd like to build myself one day.
At the time I didn't have an easy way to make the aluminium pieces. Recently though, I had a chance to make my own can-cooler inspired by Ben's version.
The idea with this device is that a drinks can fits snugly in the aluminium 'coldsink' and a pair of peltier modules(TECs) pull heat from the aluminium and dissipate it to the room, cooling down the can in the process.
