[Andrey] from RTFM has built himself a glowing LED pendant using only three parts and some simple code. The hack is not particularly complicated but [Andrey] provides some decent instructions on Pickaxe programming via an RS232 serial port and RGB LED control to produce the nice glowing effects. The pendant contains an RGB LED, a Pickaxe-08 microcontroller and a couple of button cell batteries. To cram everything inside the locket, [Andrey] had to grind down the LED and Pickaxe-08 to their minimum dimensions using a file.
All of the Basic code for the pendant is supplied on the project page and [Andrey] describes how he manages to PWM all three LED pins for the colour effects. The video after the break may be of interest to anyone who has not had a go at Picaxe programming before or for a beginner who wants to try out some new embedded devices without a big hit to the wallet.

Bot gives head to passersby
This free range robot was spotted at this year’s Kinetica Art Fair. You can place your hand above it and it will stop and pour you a beer. That’s if you consider 7/8 of a glass of head ‘a beer’.
Photo booth adds fun – consumes floor space
Face it, photo booths are fun, and if they’re free a lot of people will use them. This particular booth was built in some guy’s apartment, adding the fun but eating up floor space. But this would be a great build for your next group gathering, just like the Crushtoberfest. [via DVICE]
More human through-hole design
[Fridgehead] stuck and 5mm LED in his earlobe and then used a microcontroller to make it pulse. He’s got quite a mop and that’s where he hides the black controller pack. The next version should be RGB and the smallest surface mount packages he can solder. At least this isn’t disgusting like the LED nipple ring.
Chandelier your wife will never let you install
This 300 LED chandelier uses epoxy coated wires draped around the light ring to resemble a more traditional crystal light fixture. It’ll still be a hard sell if you want to hang this over the dinner table. [via Gizmodo]
A touch of copper
[Zombie84] built a prototype of a robot arm out of copper pipe. There’s not much info here, but you can see some wires in the wrist that appear to function as tendons. This reminds us of the characters from 9.
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]
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.
[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.
[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.
