[TUT] [C] Getting SD/MMC card working painlessly with FatFS
I solved my problem, although I still can't explain why things weren't working in the first place. All I did was remove my SD card from the breadboard and connect it directly to...

Impact detection sensor for car
bobgardner, sorry, but you are wrong with 1g decel claim. The deceleration with 4 locked wheels is not necessarily 1g. It depends on the coefficient of friction, mass of the car,...

Impact detection sensor for car
Very interesting plot. 1G for a car accelerating is pretty high. Mind if I ask what you drive? I'd love to experiment and take some measurements, like bobgardner suggests, with a...
