Hi, all... I've just gotten started with Mindstorms, and am massively frustrated with the limitations of the sensors available direct from LEGO. HiTechnic seems to have produced exactly the sort of stuff I'd like to get my hands on (multiplexors, IR proximity and short reach IR sensors, ultrasonic range sensors, etc.). Does anyone have some of these sensors that aren't being used anymore with which they'd be willing to part? Or, alternately, is there another source similar to HiTechnic which manufactures higher-end LEGO sensors?
Please email at snipped-for-privacy@intelli.com.
Many thanks,
