Fellow Canadian PIEROGRAM had some experimental fun when he was at the cottage this summer. If you have a quadcopter and want to live on the edge, strapping some roman candles to the quad might be a bit of dangerous fun. Of course don’t blame me if you burn down your house, start a forest fire or blind someone!Â
Ben shows us how he built a mock up of a Heat Reclamation Chimney. The idea is to capture some of the heat that exits through the chimney. When you have a look at a hot water tank or furnace that is basically what those devices are doing. Normally there is a heat source at the bottom and exits from the top, the rising heat passes through pipes that

Wireless devices are convenient but must be used with caution. Samy Kamkar shows us how a simple wireless keyboard can be giving away your secrets. He built this KeySweeper, it is a Microsoft Wireless Keyboard Sniffer that is built into a innocent looking USB wall charger. Via: The Hacker News “KeySweeper is a stealthy Arduino-based device, camouflaged as a functioning USB wall charger, that wirelessly and passively sniffs, decrypts,
 With portable electronics sucking all of your battery packs dry wouldn’t it be nice to have something that doesn’t take many hours to charge up? That is where the Kraftwerk Fuel Cell comes in. Fill it up with some off the shelf camping or lighter fuel in about 3 seconds. This isn’t a quick and dirty project, it has been in development for 7 years and it has
Jay_Diddy_B, a contributor on the EEVblog Forum built a great looking DIY Dynamic Electronic Load. He used LT Spice to model the design before it was built, the test result look quite good. Nice thing about the design is that there are no specialty parts, chances are you have most of the things on hand to get building right now. “The dynamic load steps the load current so that the transient
