I am glad my machine got your brains working, it does have something inside the machine to tell exactly where its operating as far as frequency and such. All of it is adjustable from the mouse pad as you saw in the video. I dont want to give too much info on how it operates internally unless someone wants to work with me on developing it a little further, I need some help with finishing touches. I will say that its almost silent, hurts about 75 percent less that conventional machines, heals in less than half the time and leaves color so damn bright I couldnt believe it. Oh and its autoclaveable too. It is a hellofa machine, I put a lot of work into it, most of the stuff like the pain and healing were accidents. I just wanted something I didnt have to tune all the time and didnt want to have to use 5 different machines for everything. With this one I just adjust where exactly I want the frequency, depth, and force then it just runs. It gets a little warm but nothing even uncomfortable to the touch which is a small drawback but you cant have it all. This is just one of the ideas I had in my head for machine design, I think I could really come up with some sick shit if I had the funds to sit and build stuff all day. The cool part really is the versatility of the motor itself, I can get the machine size down to about the size of a sharpie marker for the machine head and grip together and weight is almost nonexistant. Yo JCarlton, I am right here in Beaumont area when you want to get together on this haha. Were damn near neighbors. Hit me up Ill shoot ya my number we can shoot the shit one of these days over a cold one.
