controll this

using an xbox controller, a small lcd screen (found at compusa for under $20) you can control the media center pc, for example–change songs, pause, change volume etc

Small POV device shows off some big features

We’ve already added the components needed to build [Rucalgary's] tiny POV device to our next parts order. The little device sets a new standard for tiny persistence of vision boards. Instead of relying on the user to find the best speed and timing for swinging the board around, [Rucalgary] used an accelerometer. This is the point at which we’d usually groan because of the cost of accelerometers. We’re still groaning but this time it’s for a different reason.

The accelerometer used here is a Freescale MMA7660. It’s an i2c device at a super low cost of less than $1.50. The reason we’re still groaning is that it comes in a DFN-10 package that is a bit harder to solder than SOIC, but if you’ve got patience and a good iron it can be done. An ATmega48 drives the device, with 8 LEDs and one button for input. On the back of the board there’s a holder for a CR2032 coin cell battery and a female SIL pin header for programming the device.

Check out the video demonstration embedded after the break. We love it that the message spells and aligns correct no matter which way the little board is waved.

Reverse engineering the Novint Falcon

[qDot]‘s been spending alot of time with the Novint Falcon haptic controller. He’s put together a ‘brain dump’ of everything he know about the device – and some notes on his efforts to put together his own software library for the thing. I’m definitely interested in the parallel robotics platform that it appears to be based on.

Cubicle-dwellers rewarded for reflexes

[StudioJooj] is trying to torture or test his colleagues in his office. A lot of folks leave a candy jar on their desks for all to enjoy but he’s making his friends work for their reward. Like cubicle-dwelling lab subjects, they must successfully navigate his maze to be rewarded with chocolate. The game piece is an amazingly orb-like peanut M&M candy. The maze is constructed from plywood and moves on two axis with the help of a couple of servos. The user interface includes a couple of NES console buttons to release the game piece and a PS2 joystick to control the maze. [StudioJooj] was nice enough to include a music video in his project clip.

We wonder the M&Ms will disappear faster or slower than they would from a candy jar.

Harnessing the electrical power of clams

Yes, that is a clam. Yes researchers are using them as batteries. Yes, that quip about the matrix  and clam-Neo that is bubbling up into your temporal lobe is appropriate. While keeping a clam as “happy as a clam” might not necessitate a virtual world, they don’t really produce much electricity either. Researchers were able to siphon almost 29 millijoules over the course of an hour. This was enough to turn their electric motor one quarter of a turn.

Wether you find this kind of biological hacking ethical or not, you’ll probably agree that the following quote is, at least a tiny bit, creepy.

The researchers tried different ways to connect three clams at a time as a collective living battery. A serial circuit boosted the battery’s voltage (electric potential), whereas a parallel circuit increased the current (rate of charge flow) — but the overall electricity available often changed depending on each clam’s health.
