Hi Evan, I have done a performance measuring meter using the same accelerometers. = I assume you use the ADXL202. I used the two CCP inputs to get the two = axis readings. I'm working on a version for motorbikes as well. You can = see the meters in the products section at www.race-technology.com Email = me off list if you would like any further information. Martin >>> eshort@FERRARI.IT 07/03/01 09:44AM >>> 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. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Evan Short Ingegnere Elettronico - FERRARI S.p.A. GES v.
