Fresh hacks every day
[Todd Harrison] needed a way to run a 12 volt PC fan from mains voltage. Well, we think he really just needed something to keep him occupied on a Sunday, but that’s beside the point. He shows us how he did this in a non-traditional way by using the resistive load of an incandescent light bulb, a diode, and a … Read the rest
[Fish] is really proud of his newest creation, the Hydrocrystallophone. This new instrument reminds us of an even more steampunk version of [Benny Franklin]‘s glass armonica – an instrument that reportedly plunged the player into a, “dark and melancholy mood.”
The build is based around a 1920s hand-cranked phonograph motor. The phonograph motor spins a wine glass … Read the rest

Unlike a few other balloons we’ve seen, the Apex team is doing it right and giving everyone the downlink details for the balloon.

We checked in on the project at one of … Read the rest

It also has the ability to stream the data over USB, but that feature is only supported in Windows and the companion software leaves a lot to be desired. Here’s a technique that will let you unlock the potential … Read the rest
[Joel] dug up this hack that he pulled off over ten years ago. It’s inspired by the Nintendo PowerGlove, and uses flex sensors to react to movements of your fingers. The interesting thing is, he built these optical flex sensors himself.
He likes to say that this is a ghetto fiber-optic setup. The inlaid diagram above gives you an … Read the rest
[Jonathan Thomson] just finished writing up his entry for the 7400 logic contest. It’s a voltage doubler that uses a 74HC14 logic chip. Because this is not at all what the chip was meant for–and he’s a sucker for puns–he’s calling it the Illogical Dickson Doubler.
What he’s got here is basically a charge pump built from a set … Read the rest
