I don't know if my beef is with the samples I've got or if the problem is simply the nature of the build. I will be in touch with spectrasymbol to find out more on the matter shortly.
The problem is threefold:
First off the sensor output seems to jitter/oscillate (for want of better description), This means that the aquired data has to be scaled and/or filtered to a usable range. In this instance I have scaled to give a musically useful range of 12 intervals. Though to obtain a more discrete range one would need to attenuate the jitter somehow or simply have a much longer sensor strip. I am testing a 16mm sensor and a a gang of 3, 14mm sensors.
The second consideration is that at rest the sensors output ten percent potential and don't settle at zero resistance. Since their full resolution is still available if taken into account this 'can be' a positive advantage.
Finally and for my purposes the larger factor occurs after actuation of the sensor, the decay of the signal can take up to 5 seconds to return to a state of rest!! yet continuous control is fine.
So if I could get rid of some of the jitter and make more discrete sensor readings these small sensors would be great, though at present floating point resolution seems not so plausable. Any suggestions that you might have would be appreciated.
