Awesome video, mate! Despite the compression imposed by Youtube, the acoustic spectrum is excellent.Johansson wrote: As you can see we had a very successful first test.
Motor resonance frequency (via f1-f6 series weighted average) is 163.3-163.5 Hz (excellent agreement);
with peak acoustic power at f3 (spot on), followed by f4, f2, f5, f6 and f1 (yes, fundamental is weakest).
Music to mine ears!
