Sure, it’s been done before, but that doesn’t make the idea of a robotic arm controlled by a Wiimote any less exciting, especially when the arm is actually responsive. That feat is aided considerably by the fact that this latest setup was developed by an engineer from National Instruments, who made use of some of the company’s LabVIEW hardware and a specially-designed Bluetooth adapter to control the arm at the flick of a wrist (or using the Wiimote’s buttons). Check it out in action in the video after the break — don’t worry, no one gets hurt.

DIY virtuoso Johnny Chung Lee has already more than proven himself with his Wiimote whiteboard and finger-tracking hacks (to say nothing of the famous $14 steadycam), but he now looks to have vaulted himself into a whole new league with his latest project, which uses a Wiimote for a full-on VR head-tracking system. As with his other recent hacks, the Wiimote and a sensor bar substitute swap their usual positions, with a pair of IR-equipped safety glasses stylishly getting the job done in this case. Toss in some custom-made software (available at the link below) and you’ve got a setup that’s sure to make anyone’s jaw drop. Whatever you do, be sure to hit up the video after the break (and watch ’till the end), as the image above certainly doesn’t do it justice.

While certainly there’s been no shortage of Wiimote hacks, the number of genuinely useful ones has been considerably more limited. It looks like you can now add one more to that list, however, as Johnny Chung Lee (he of the Wiimote finger-tracking hack) has now upped the usefulness even further with a makeshift multi-point interactive whiteboard. There’s a bit more involved with this one than just a Wiimote, however — namely, an IR-emitting pen (or two), which the Wiimote tracks while relaying all the necessary information back to a PC. That, as the video after the break shows, allows you to turn any surface into a multi-point whiteboard with the use of a projector, or turn any LCD screen into a touchscreen, of sorts. Best of all, Johnny has kindly provided the necessary software free of charge, so hit up the read link below if you want to give it a shot.
