NXT Motor multiplexer by Mindsensors

While browsing the Mindsensors website , I noticed that they're working on a new motor multiplexer for NXT motors. The device allows you to control two additional NXT motors and it requires an external battery pack. You connect the multiplexer to one of the NXT sensor ports, but you won't loose a sensor port as you do this, because you'll be able to connect a sensor to one of the multiplexer ports which acts as a sensor port.

Nice NXT site: NeXTSTORM

Some fellow at the MCP pointed me to a very nice NXT-related web site by NeXTSTORM that presents a lot of interesting NXT models, alongside with pretty well-made movies and some LDD-based building instructions. One of my favorites: the " Ultimate 100 Meters Race ", including an ingenious analogue multi output device: Have a look there - it's worthwhile!

New Products From HiTechnic

There were several very nice surprises in the new LEGO Education catalog. Besides WeDo, there are three gems from HiTechnic . The first is a simple touch sensor multiplexer for the NXT. The idea is that by combining multiple touch sensor on one input port (but giving each a slightly different resistance), you can detect not only when one is pressed but which one is pressed. This was something that was commonly done with the RCX, but there hadn't been a commercial product to do it as yet for the NXT: it appears HiTechnic has stepped up and filled that gap. Four touch sensors can share a single input port on the NXT, greatly expanding the number of touch sensors you could use (at least 16; enough to build a simple keyboard, perhaps). The square "bumps" on the housing are spaced so that a studless beam nestles neatly between them, allowing you to "clamp" or "bracket" the housing in place (without going to the trouble of LEGO-certified pinholes etc.).
