Fresh hacks every day
This is the control and monitoring hardware which [Jack] built for his campfire electricity generator. He’s done an amazing job to get this far. You can see he’s pulling 1 Amp at 14.2 Volts off of the system. But there one gotcha that’s still plaguing him.

However, in order to reduce noise in the pictures, he had to cool the camera down. He based the project on a peltier … Read the rest

The system uses two Peltier units, each running at 91.2 watts, with computer heat sinks mounted on one side of the unit to dissipate the excessive amounts of heat generated. While he was originally trying to build a cooling backpack, the use of the Peltier units … Read the rest
Hacked Gadgets pointed out this great peltier based beverage cooler. It has a pulse width modulation based controller driving a 12V 80W peltier. Alan also pointed out Hack-A-Day reader Chris Garrison’s peltier beer cooler from last summer. The Defcon cooling contest from last year also featured a peltier based cooler.
