If you thought [Johnny Lee] was done making us all buy Wiimotes, you were wrong. Now he’s back showing off a simple, but incredibly effective VR head tracker. He swapped out the LED’s on a pair of LED light safety glasses with a set of IR LEDs and used his PC/Wiimote combo to do the work. The demo is just fantastic. As usual, you can download the software from his project page.
Wiimote Projector Whiteboard
[Johnny Lee]’s back again with his Wiimote interactive whiteboard. Commercial versions of these things are expensive and heavy. His technique doesn’t even need a projector, just a computer, a Wiimote and a simple IR emitting pen. The pen is just a stylus with an infrared LED in the tip. Hit the video after the break, and you can grab the software from his site here.
Reader How-To: Wiimote Horse Controller
I linked the Wiimote horse controller in yesterdays extra, but today [Mark] sent us a short and sweet How-to. Essentially, he’s using the Wiimote taped to the horse as a joystick to play Need for Speed on the laptop connected to his big screen. Hit the read link for his write up.
Wiimote IR Finger Tracking
Just in case you needed another way to pretend that you’re in Minority Report, [Johnny Lee] sent in this video showing how to track your hands using the Wiimote’s IR camera,an infrared LED array and a bit of reflective tape to improve the gain.
Wiimote Firefighting Robot
Chad brings us yet another use for the Wiimote: firefighting robot. The Wiimote acts as a communications gateway via bluetooth to a host PC. The IR sensor is used to detect the fire, and the commands from the host are passed along via the Wiimote expansion port. The robot is pretty basic, but the use of the Wiimote to relay bluetooth comms via I2C is a fantastic hack.
Wiimote On Your XBox 360
[UberNoober147] and [Carey] both sent in this round about hack. The Wiimote is interfaced with a PC. The PC outputs to a micro-controller circuit that outputs PlayStation 2 control signals. That’s connected to a XFPS – a PS2 to XBox 360 controller converter. It’s definitely round about, but it works.
Wiimote Car Accelerometer
This one’s pretty simple, but anyone who’s ever spent time tweaking an engine will appreciate it. [Kevin]’s been using a wiimote to measure the acceleration of his car. He put together a script to dump the accelerometer output to a CSV file, then graphed it with Excel. He notes that the accelerometer output isn’t that precise, but it’s good enough to give you feedback on your mods.
