/diy/ - Do It Yourself

Doesn't look very efficient since it doesn't have any cooling fins. You could probably improve the heat dissipation with next to zero cost by hammering copper nails through the bottom of the mug, then bolting on a plate of scrap copper to better distribute heat to the nails(probably better to solder it on if you have a soldering torch handy), then finally bolting your chip on the whole thing.
