Fresh hacks every day
Green hacks implement one of two philosophies. The first is über-technical, with very expensive, high-quality components. The other side of this coin creates green power out of junk. [Timot] obviously took the latter choice, building a windmill out of an old washing machine motor and a few bits of PVC.
The generator for the windmill is based on a Fisher … Read the rest
We’ve seen a few of the projects from The Deconstruction, a 48-hour build-a-thon for hackerspaces and other groups around the globe. Of course Tymkrs, a pair of geeky vloggers famous for their building prowess, were part of The Deconstruction, and in the process they came up with a few really cool builds at their hackerspace, The Rabbit Hole, in … Read the rest
Generating power from wind is easy – just stick a windmill on a pole and attach a generator. That’s not particularly cool, though, so [Adrien] and his team from his senior design project are using an autonomously controlled kite to generate power
The basic idea of generating electricity from a kite is to fly it around in figure-eights while unwinding … Read the rest
Steampunker extraordinaire [Jake von Slatt] loves the idea of solar-powered garden lights soaking up the sun’s rays during the day and powering a LED in the evening. Commercially available solar lanterns, as [Jake], you, me, and everyone else on the planet have discovered, are universally terrible and either don’t have solar panels large enough to charge a battery, or only … Read the rest
[Paulo]‘s got a few solar panels on his shed, and while he does have a fairly nice setup with a battery charge controller, he found himself looking around for a panel voltmeter. Of course you can buy a panel voltmeter for under $20, but [Paulo] wanted something that fit his 4-4-4 plan; his voltmeter should cost under $4, draw less … Read the rest
We absolutely love these stories of hacker ingenuity saving peoples lives. In this case, it was aboard the ISS, and the item being hacked was a toothbrush.
The story is as follows. Some equipment failed, as space junk tends to do, and the astronauts found themselves needing to do some repairs. Upon inspection, they couldn’t remove some modules … Read the rest
For [Justin], the topic of remotely powering electronics in the field comes up often. So often in fact he decided to put up a tutorial for powering electronics from solar power and batteries, as well as sending and retrieving data with the help of a cellular connection.
The electronics [Justin] chose for his remote wireless project include an AT&T … Read the rest
