The software uses an automatic calibration of the base-line every time no pressure is detected. So even after replacing the membrane you usually don't have to re-calibrate the device manually. On the first setup you have to define by a single number the sensitivity of your setup (mainly dependent on you hall sensor, magnets and distance magnet vs hall-sensor) so that the maximum blow (where usually the membrane magnet hits the top acrylic plate) outputs a CC value of up to 127.

== How it is build ==

Usually people (like me) use instructions like this only for own inspirations, so this is not meant to be a full "how-to-build" instruction, but it should give you enough insights to do so if you want. In the rare case you really build this and make it to work please drop us a mail :-)

All parts are laser-cut from a very thin (0.5mm) like acrylic sheet and a thicker (4mm) acrylic plate. The 0.5mm acrylic is more like a foil and much more flexible than the 4mm glass like sheets. These are the files with the laser cut parts made with Inkscape:
