Is GEK a modern-day Mr. Fusion?

[Nanomonkey] spent the weekend building generators that run off of syngas. All Powers Lab produces Gasifier Experimenter Kits to convert raw material to energy. The kits use Gasification to make a “natural gas like” fuel from materials such as wood chips, walnut shells, construction debris or agricultural waste.

So is this the Mr. Fusion that powered the DeLorean? This Honda fitted with a GEK sure makes it look that way. But all joking aside, this looks like a great way to turn waste in heat or electricity. There’s tons of info on the site to dig through. The controllers are open source which would make it easier to interface with the Google PowerMeter when the system is used as a generator.

DIY projector collection

Reader [Jan] came across a website all about building your own video projector. We’ve linked to five of the best projects for 2010 but there’s a ton more information if you dig a little deeper. Our favorite so far is the GohtanBox v3 and it’s giant LED panel that serves as the projection light.

Google unveils API to PowerMeter

Google’s tentacles continue to wrap around every portion of our lives with the addition of an API for their PowerMeter software. The PowerMeter tool works with smart electricity meters to monitor and display power usage in the home. This will allow manufacturers (and hackers alike) to design new devices with the Google interface in mind.

We’ve got an old-fashioned power meter with a spinning dial and no blinking LED. This means we can’t monitor that blink to add our own PowerMeter interface. But if you do have an easy way to grab data from your meter you can design a home system that takes full advantage of Google’s tools.

Ok, who’s going to be the first to have their Google PowerMeter-compatible hack featured on Hackaday?

Using Mindflex to shock the heck out of people

We love to see eloquent hacks but this isn’t one of them. [Aaron] and his fellow sadists are using a Mindflex game with an electric shocker. If your brain is idle you’ll be fine, but too much activity inside the noggin and you’re in for nasty shock to the arm. Take a look at the video (bleeped but probably NSFW) after the break.

We’ve seen the Mindflex before, they’re using its interface in the same ways we’ve seen the Force Trainer used, by tapping into the LEDs. The shocks are provided by a Qkit, so hopefully there’s enough engineering behind it to keep the ‘contestant’ safe.

Hey, isn’t that the Tron Guy?

Home cinema 3D (or just tick off theatergoers)

After a visit to the local theater and discovering the use of IR 3D glasses (for films such as Avatar), the team over at Furrtek wondered how they worked, and more importantly, how the glasses could be manipulated to tick off audience members. While the original intentions seem a bit childish, they did mention that their final setup could also be used for a home cinema with IR 3D glasses.

Onto the good stuff: the glasses receive IR light pulses timed with the movie to black out the appropriate eye with the appropriate frame and producing a 3D effect. With the use of IR Investigator the team grabbed said timings; it was then simply a matter of building their own IR projector, and bringing it back to the theater to annoy the crowd setting it up for their 3D home cinema.
