Hello All,

I've developed a special adjustable capacitor for tuning Tesla Coils.
I've tested and used it for 2 years, and was going to patent the idea 
but honestly can't afford to.  So here it goes, an adjustable 
capacitor rated from .001 mfd to 1 mfd in .001 mfd increments...it 
can tune any Tesla Coil exactly and can be easily built by all by 
off-the-shelf materials.  Best of all there are no moving parts...its 
all done mathematically - and using simple math no less!

   The same general "binary" design, sometimes using special 
switches and sometimes how, has been in use for a very long time.  I 
have a bunch of power factor correction capacitors fof WW2 airborne 
radios which operated from 400~ power.  They go from 1 ufd to 21 ufd 
in 1 ufd steps.
I just connect to them with toggle switches and find them very useful.
I'm pretty sure a lot of precision resistor boxes do the same thing, 
adding in series rather than in parallel.
