Fresh hacks every day
We’re not quite sure what’s going on with our fellow hackers lately, but they all seem quite interested in finding inventive ways to scramble their brains. [Ben Krasnow] has put together a pair of videos detailing his experiments in transcranial magnetic stimulation, a process that looks like it would go quite nicely with the Brainwave Disruptor we showed you just yesterday. Instead of … [Read more...]
Flickr user [n Bryan] has been keeping busy lately, trying his hand at developing some cranial electrotherapy stimulation instruments for home use. While visions of [Peter Venkman] electrocuting hapless college students initially came to mind, this sort of therapy is not the same thing, nor as painful as what is depicted in the film. Cranial electrotherapy stimulation relies on small currents … [Read more...]
[hedgehoginventions] wrote in to share a little modification he made to his video card in order to keep it from overheating during strenuous 3D tasks. Having swapped out the stock cooler on his Nvidia 9600GT graphics card, he found that it did not need to utilize the fan while doing mundane things like checking email, but that it still required extra air flow while playing games. He figured he … [Read more...]

As he was picking through parts bins at his local hackerspace, he thought it would be fun to build an “Executive Decision Maker”. The device he had in mind would answer questions at the push of a button, with the kind of … [Read more...]

Sometimes though, you just need a power supply.While there are a million tutorials out there, not many go as in depth as [Phil] does in his 2 newest videos. Covering everything from the wall outlet to the final output, [Phil] explains … [Read more...]
This pressure cooker hack on [Dave Arnold]'s great cooking blog was sent into us (thanks, [techartisan]!). Most pressure cooker recipes are written for pressure cookers that can go up to 15 PSI or 250° F / 121° C. At these temperatures, a lot of interesting chemistry happens in the food. The popular Cuisinart electric pressure cooker doesn't reach these pressures and temperatures, so [Dave … [Read more...]
