Łukasz Martynowicz Posted September 19, 2014 Share Posted September 19, 2014 @Matthew: I've posted a link to an example of a two-way air pressure sensor in my DIY thread some time ago. As to pistons/bellows replacement, if you can live without true bellows (travel distance) then you can adapt the same pressure rod solution as the S-Wave, or combine the air pressure sensor with something like this: http://www.chawison.pl/35,gruszka-powietrzna-z-pedzelkiem-do-czyszczenia-2w1,354 - it is an air bulb for cleaing of photographic equipment. You could also use air cylinders but I didn't dug into this solution, I just have made some tests with LEGO cylinders I had at hand. The most important requirements for such cylinders would be long travel, light weight and most importantly low pressure operation (low friction/low initial resistance is crucial for fast responses). IMHO if you want as close imitation of an acoustic concertina, then traditional bellows operation is the most logical solution. I was considering other options mostly because I want a hybrid controller, i.e. for wind AND velocity driven dynamics. Quote Link to comment Share on other sites More sharing options...
