My wife is wanting some boot warmers and for the first time I started looking around and couldn't believe the prices they are asking for the hotronic stuff. $50 for a simple "wall wart" transformer with a timer in it to drop to trickle charge in 12 hours, $55 for a simple NiMH batter pack with a dial that just switches between 4 resistors! I was wondering if anyone had ever taken on a do-it-yourself bootwarmer? It would be pretty easy to build a battery pack and a charger, but I don't know what voltage the hotronic battery packs are. Is there one cell (1.2V) or 2 cell (2.4V)? And what capacity are the battery packs? I may just buy a heating element and experiment. If anyone else has ever built anything like these, please post your results.
