Tappeto con sensori di pressione DIY

imsolidstate] built his own pressure sensitive mat. It utilizes two discs of copper clad board with a piece of foam in between for each of 64 sensors. As the foam gets compressed, the capacitance between the two pieces of copper changes, a measurement that is fairly easy to make with an analog to digital converter. The mat is being used to measure how well a horse saddle fits the animal. Data is read in through a serial port and then mapped using Excel. This prototype proves that the concept works but [imsolidstate] mentions that there’s room to improve the sensitivity and that there could be more noise filtering incorporated into the design.

Il tipo ci pesa i cavalli, ma a me è venuto subito in mente un modo cheap per realizzare il pavimento che si illumina come sul video di Michele FiglioDiFante… :-)
