Violet Ray Machine

[debodun]

A questionable antique medical device. Works on electricity. A knob controls the intensity of the beam. Various attachments are made for use on different parts of the body. Mine works (the last time I tried it - not to cure anything, just to check it), and it has a booklet with it with instructions and to order more probes. Some of the scientific background can be read here, if interested:

Good ol' Tesla. Should have known he would invent this.
I worked on sophisticated (at the time) and state-of-the-art lasers for about 10 years and became fascinated with the many applications of light both non-laser and other.
