[kylemcdonald] has posted this how to build a simple 3D tracking interface. Using 6 resisters, some wire, aluminum foil, an Arduino, and a cardboard box, he was able to do 3D capacitive sensing. Coupling that with Processing, he was able to overlay an interface using augmented reality. The video above shows a 3D tic tac toe application. While it seems less than perfect, its pretty amazing for how simple it is.
Seen anything similar to this out there? What applications would be fun with this?
[Adam] sent in his robot: Ard-e. It’s build on a cheap remote control bull dozer kit along with a pile of cheap parts. He managed to keep the cost under $100. You might be getting sick of the Arduino love, but we love how the platform makes it possible for the micro controller novice to get results without taking advanced assembly language.
Sparkfun has recently released a bevy of new boards and other devices, with some very intriguing new builds among them.
The first board that caught our attention is the Wee. It is a compact Arduino compatible controller that features a small size, low voltage, and many other minimalist attributes. It is built around an ATMega 168V and uses all SMD parts.
For even tinier fun, check out the LilyPad LED. It is a LED designed to be incorporated into clothing, featuring large holes for threading, a thin and extremely small PCB and a very bright 250mcd light. It is also washable, meaning that one or many can permanently be incorporated into clothing without fear of losing them. You can see these in the turn signal jacket we covered earlier.
The last one we’ll discuss is the LiPoly Charger, a USB lithium ion battery charger. Based on the Max 1555 IC, the LiPoly can use USB bus power or a 2.1mm center positive wallwart power(it uses the more high-powered wall-wart if both are connected). It can’t charge NiMH batteries, but it is still compact, efficient, and very useful.
[Windell] was stoked enough to send us [Jay]’s sweet hack on [Windell]’s Evil Mad Scientist Laboratories Peggy 2.0 kit. [Jay] added serial input and hacked quartz composer on his mac to light up all 625 LEDs with live motion video. If you were jealous of the Metalab’s giant LED display, now you can have your own – smaller and cheaper.
EMSL has recently supplemented this awesome device with their Arduino Library for Peggy 2.0. It is a program library that contains various animations and demonstrations of how to draw on a Peggy. Download and enjoy them as they are or tweak them to test out some of Peggy 2.0’s capabilities.
If you’ve been looking for a cheap way to do motion capture on 3D Studio Max, [melka] has devised an ingenious way to do mocap using a Wii nunchuck. As shown in his Vimeo video, the nunchuck is connected to an Arduino that feeds MIDI data to a computer running the MIDI app Ableton Live. Ableton Live feeds that data to 3D Studio Max via MIDI Yoke.
The video below the break shows that the motion of the nunchuck can be seen in real time in the 3D Studio Max Window. We’re really hoping [melka] will post a writeup of this project soon, as we are hungry for more details.

Modern Device’s Really Bare Bones Board is an Arduino clone designed to have an incredibly small footprint. It’s barely wider than the requisite AVR and is laid out so you can reduce the size even further. Don’t need the power connector? Just snip it off. Don’t need the voltage regulator? That can be removed just as easily. The kit is only $12 and all through-hole components. [youevolve] posted a build guide that shows exactly how easy it is to assemble.

A short while back, [Chris Anderson] released an Arduino based autopilot. It rings in fairly cheap and being open source, you can tweak away. To add more functionality, he’s releasing a dual core version. Thanks to the second processor, it no longer requires an external hardware co-pilot. It uses an on-board GPS and features an ATtiny based fail safe. It’s still under development, but he’s made the design files available.
