(...) Excellent suggestion!!! We'll open one sensor and try once again. (...) (URL) else interested in repeating the experiment? Philo? Claude P.S. I added a graph to the page, where the sound pressure is maintained constant. (16 years ago, 28-Feb-09, to lugnet.robotics, lugnet.boats)

(...) Since I was doing this all manually, it was by far the easiest. I realized that a better way would be to vary the signal generator level at each frequency, but often when trying that I simple "maxed out" the reported level from the sound (...)

Thanks Brian (...) Your excellent graph shows that you tried to maintain the sound pressure constant. We did the inverse in the last graphs, where we tried to draw the curve for a constant NXT sensor value. We also repeated the experiment, and this (...)

(...) anything interesting at 3 kHz... perhaps because I didn't go that high (oops). To figure out the frequency response I did it manually: I borrowed a signal generator and speaker from the university, as well as a sound meter, and then simple (...) (16 years ago, 28-Feb-09, to lugnet.robotics)

| | Re: Learning LSynth
|
|
(...) That is great news. It means it should be relatively easy to add any new parts LEGO introduces (like the treads, or the NXT cables) without having to change the actual program. I'm looking forward to the release. Jetro (16 years ago, 27-Feb-09, to lugnet.cad, FTX)

We've worked some hours to do some interesting experiments with the NXT sound sensor in order to learn more about the sensor characteristics: Please consult: (URL) and help discussing. Claude Baumann (16 years ago, 27-Feb-09, to lugnet.robotics)

(...) Wow, that is new. The Americans have been complaining about this for a couple of years at least but I have never seen retail prices above MSRP in Canada before. I hope it is an aberration not the start of a new way of doing things at TRU. - (...) (16 years ago, 27-Feb-09, to lugnet.loc.ca)

(...) Also, the new LSynth combines adjacent segments to minimize the number of segments in a hose. As long as adding the next segment does not push the overall angle beyond a an angle threshold, the next segment is merged with the current segment. (...)
