Nice work! For a while it looks that you could travel back in time using this recording device, before you realize that the pen draws an arc when the paper doesn't move ;-). Could it be possible to add a rotational sensor and datalog the time and angle to analyse the data numerically? -- et C S Soh <cssoh@singnet.com.sg> wrote in message news:37F015F7.BD9C799A@singnet.com.sg... > Hi, all pneumatics fans, > > For some time I've been trying to figure out how to objectively compare > the performance of the various air compressor designs especially the > ones using the large pneumatic hand pump which seem to be coming into > fashion lately. > > After much thought and several failed attempts, I've come up with an RCX > Controlled Air Compressor Tester.

(...) Thanks, Indeed, my first attempt was to use a rotational sensor positioned with the axle at the pivot point of the lever arm and tried to datalog the angular movement using DACTA Control Lab. However, the resolution of the rotation sensor (...) (25 years ago, 28-Sep-99, to lugnet.robotics, lugnet.build, lugnet.robotics.rcx)

Hi, all pneumatics fans, For some time I've been trying to figure out how to objectively compare the performance of the various air compressor designs especially the ones using the large pneumatic hand pump which seem to be coming into fashion (...)
