measuring vibration in pool cues and cue wood
measuring vibration in pool cues and cue wood
(OP)
Hello,
I am trying to measure the vibration in the wood used to make pool cues as well as the shape of the stick taper and the materials used in the joint of a 2-piece stick (brass, steel, plastic). I am trying to investigate the feel in a more quantitative manner.
I have a PC with a 24-bit sound card and have been looking at the capture units that in interface with a PC.
This is a hobby project, so the budget is not big.
Should I be looking at accelerometers or microphones?
What kind of capture unit should I look at?
Any particular software?
What about the sensor/capture unit or sensor/computer interface?
Thanks for the thoughts.

This has a good trial software package: http://www.purebits.com/
Use software to record through soundcard and mic, run FFT on intersting range(s)...this produced very plausible results for my tool theory.

May I suggest strain gauges to pick up the vibration - they will pickup Hz >> than the 20kHz that a microphone does. Also you will get displacement and not just frequency. Easier to mount also.
Sometimes they are available very cheap on eBay.
