HHO RESONANCE – How to find resonance frequency!

-=:WATCH IN HIGH QUALITY:=- ***UPDATED:*** This is not the Resonance that people trys to get to hit with the power supply (PWM). I thought it was but people taught me that it isnt, but i decided to keep the video, so at least people can tune their tunes like stan meyer did with high precision! Its a good method for those how dont have much trained ears, and all you have to do is cut a slot in larger (lower pitch) tube so its pitch go higher, and the idea is to mach all lower frequency tubes to the one that is higher frequency, once the reverse is not possible.*** My voice was post recorded. I ran 3 tests with diferent devices. #1- Phonic Spectrum analyzer PAA2 #2- Beyer Dynamic MM1 measurement Mic into a M-audio 410 Soundcard and Wavelab software #3-Creative low budget multimedia microphone into computer’s mic in and Wavelab software aswell The 2nd test gives you a better result because the 3rd is full of noise floor making your SNR low, but as you can see it also works! Thank you for watching and leave comments! Good or bad, all welcome! Bye!
