Apple Magic Mouse on Windows

Looks like some folks snooped around the latest Bluetooth update from Apple and managed to extract the Magic Mouse drivers. Now you can use them to take this complex peripheral for a spin on Windows. [Thanks Juan]

Component jewelry: From geeky to gross

[Nikolaus] made a pair of 300k Ohm earrings for his wife. That’s three Brown-Black-Yellow resistors per ear. It’s geeky but in a subtle way. Much more refined than the gross outcome of this other guy’s crass nipple experiments. Need to get the image of nipple-jewelry out of your head? [Nikolaus] has you covered with some 3d printed earrings.


Need your GPS data to be accurate within a centimeter? We don’t either but if you ever do, Real Time Kinematic GPS is what you need. Now you can build one yourself using the RTLIB package. This is based around the powerful and powerfully-inexpensive Beagleboard. [Thanks Jan]

Messy music

It warmed up here a bit this week and things got slushy. Our Galoshes are nice and water-tight but [David's] have a big hole in the side and are filled with a mini-keyboard. He’s chosen a rubber boot as the housing for a circuit-bending project. It’s a nice touch that the hidden keys are still playable through the flexible rubber.

Electronic Jewelry


[Ellindsey000] posted this neat little pendant to his flickr stream. We like the way it looks, and the fact that it is a functional circuit. The schematic is even pretty neat. We would maybe wear this, as a belt buckle or something. When we looked at this though, we thought it looked really familiar. Yeah, it kind of looks like the arc reactor from Iron Man, but what we thought of was this cool looking walker. As you could probably already tell, it’s the same person. Great job again [Ellindsey000], and thanks for posting the schemtaic.

Modifying a sonic cleaner for the lab


[Sean] wrote in to tell us about this hack he did to modify a consumer sonicator for lab use. Sonication is often used in labs to aid in mixing in difficult containers or to add energy for certain events.  He’s a chemist on a budget, so he couldn’t necessarily afford a nice industrial one. Instead, he found a sonic jewelry cleaner.  The main shortcoming of the consumer level one is the fact that it can only go for 3 minute intervals. He needed up to an hour at a time. His solution was fairly simple, he closed the circuit to force it to be continually in the on position, then added a timer in the power line. He notes, that the consumer model wasn’t made to be run this long and could possibly produce enough heat to damage itself. It should not be turned on, then left alone.
