All this talk of increasing visibility has suddenly become of more interest to me, given that I'm recovering from an argument with a Land Rover which turned across my path (Oh, I didn't see you) in traffic. Turns out that my motorcyle and I weigh a lot less than a Land Rover. Only a mind hand fracture, thanks to a good helmet, good jacket, leather pants etc... Getting to the point, though, I'll be looking into a headlight modulator, evidently having your highbeams on during the day doesn't cut it with Italian drivers - I don't know if they're legal in Italy but I think I'd rather risk the ticket from the usually absent local police than another encounter with a Land Rover. Ironically, I had already modified my bike to make me more visible from behind - I built a brakelight which activates a row of high intensity LEDs - more LEDs for heavier deceleration. I've always thought that this was important on a motorbike, as you can be decelerating quite heavily from engine braking alone before you touch the brakes. Using an accelerometer, the drivers behind get a warning before your main brake light comes on. I used a PIC, naturally, a 12C series reading the digital output of an Analog Devices surface mount accelerometer and controlling the lights. I'd be interested in knowing if anyone else has done a similar project. Keep the rubber side down, Evan. ==================== Evan Short Ingegnere Elettronico - FERRARI S.p.A. GES v.
