How is this device targetet at the hair?
Do you have to point a needle tip thing to the skin there the hair enter?
I dont understand how high frequency can be part of the trick, but maybe
have something to do with concentration to the hair root, i dont know.
Anyway, it is a design trick to make the output transformer very small.

A very simple driver/oscillator for that transformer might be constructed
from only a transistr and a few C and R, but probably work better and have
less power consumption (good for battery) if built more advanced.  And you
wish to control the voltage and current.  There is of course also a
question of EMC...

I believe the whole thing can be built in form and size of a electrical
tooth brush  (just dont put the depilator in your mouth and kill your
teeth...!)

To stay on this lists topic, use a PIC for timing of the treatment, battery
charging, flashing a LED or whatever seem fancy  ;)

It seem to mee you already have all information necessary, written like
this: f=1MHz, current limited to 45mA, and voltage limited to 800V.

A more sporty non-cheating way is to try out the currents etc on yourself
(not your girlfriend, if you wish to keep her... )
