So I have recently been made aware of the Multipick which retails for like $2000 (Canadian) and I want to attempt to make an electric pick gun that will work as well offering the same capabilities(frequency adjustment, changeable pick tips, and throw control) minus the ability to save preset frequencies. I had a game plan all sorted out, it was going to be rough and dirty, I had planned on starting with wired hair clippers and wiring in a dimer switch(rheostat) which would allow me to adjust frequency and if you were so inclined a car battery and an inverter and you are mobile because I don't really care about that aspect of it I was going to skip that part as I cannot seem to find my inverter anywhere

and its not worth $50 for me just to prove I could leave the house with it while sitting at my desk. I still think this is a solid plan however hair clippers operate around 150hz Id say I could tweak the throw(shorten wavelength) and voltage to the motor and maybe get 250hz or 15000 vibrations/min. The Multipick is claiming 44000. I would like to know if that is true any info would be greatly appreciated. I have been looking in to eccentric motors all day and I just can't see how they would be getting that high of numbers that's 733hz. I am now thinking I might need to modify a cheap rotary tool that is capable of 35000rpm instead of hair clippers. Input much appreciated
