Pressure DAQ Board
by Carson Reynolds
This past winter I worked with Alda Luong to make a printed circuit board for my pressure-sensitive mouse. The old board was a 3m protoboard that was NOISY as a punk rock show. So we documented the logical connections that I’d made in a delirium while working on my thesis. We then laid out the components in Eagle. The resulting boards work pretty well, but we accidentally made the traces too thin. The Daimler-Chrysler concept car project decided to use them to read from force sensitive resistors mounted on the steering wheel and shift knob. I sank several hours yesterdays testing and integrating the board into the concept car.
