Hitachi's StarBoard FX 77 Duo multi-touch white board seemed impressive enough when the company announced it late last year, but if you've been waiting to see one in action before you transported your classroom into the future, Hitachi has now got you covered with a couple of demonstration videos. In this case, Hitachi has paired the rig up with its CP-A100 short-throw projector for maximum showoffiness, although it seems you can use it with any projector of your choosing. That, of course, also means that there's no electronics in the board itself, with the necessary cameras and other electronics contained in the sensor bar at the top -- which, as our presenter helpfully informs us, could come in handy if you want to drill a hole through it. Head on past the break for the full show.

Sure, there's plenty of hackery going on with interactive whiteboards these days, but that doesn't mean plain old marker-based boards have been left out of the fun completely, as evidenced by this latest contraption devised by Sprite_tm. As you can see in the video after the break, he's managed to rig up a slightly precarious system that'll write out any message you send it over the web, and with surprising legibility no less. To do that, Sprite salvaged some parts from an old scanner and printer, along with an ever useful microcontroller, an x/y stepper system, and some rather clever touches like an electromagnet to keep the marker on the board. He even bravely opened up the board to the public, although that unsurprisingly doesn't appear to have lasted very long. If you want to give one a shot yourself, however, you can find most of the details you'll need and the necessary source code by hitting up the read link below.
