I connected to 13 volts instead of 5 volts for a brief moment and it fried. The manufacturer says it was a noise filter in the top right hand corner.Photo: I removed the fried component and found that if I jumped the tabs with a piece of wire that I get a voltage of 1.8, but it should be 2.5.Photo: Luke's friend Benny who is a electronics whiz said he thought the tiny little component was some form of a resistor. When I asked the company what the component was so we could try to fix it, they offered to replace the sensor. I took them up on that.Photo: The pretty complete rigid rider setup on the instrumented bicycle. Everything seems to be working pretty well.Photo: Photo: Photo: Photo: Photo: Practice bump for the pitch rate gyro sensor.Photo: Another bump.Photo: Where I've been sitting for the past 4 weeks.Photo: Photo: Photo: Photo: Redundant rate gyro and accelerometer.Photo: Photo: Photo: Calibrating the pull force load cell.Photo: Busted cable for the seatpost on the amp box.Photo: Knee plate mock up.Photo: Bump profile in posterboard.Photo: Bump profile in poster board.Photo: Home made 1/4-28 eye bolts for the pull force load cell.Photo: Steven working on the knee restraint design.Photo: Photo: Rough cut of the bump.Photo: Photo: Steven at the mill making mounts for the knee plate.Photo: Photo: My Dad would be proud of my woodworking skills.Photo: Clamping the bump.Photo: Me locked into the body cast for the first time.Photo: Amp box is mounted to the rack.Photo: Attached the body cast to the support arm.Photo: Finished the bump with some sanding.Photo: Finished knee restraint plate.Photo: Photo: Knee magnet strap.Photo: Sewing up the knee magnet strapsPhoto: Photo: Photo: Photo: I'm pissed at this one.Photo: The DAQ and laptop mount looks good in pink.Photo: The NI DAQ is underneath.Photo: Knee magnet.Photo: All the sensors work, now I just have to get the software to be reliable.Photo: Adding some metal edges to the bump for strength.Photo: Completed bump.Photo: Photo: The bicycle is finally finished.
