The EICO EC-700 must harbor the same black-project tech as  'Magic' Alex' 
Nothing Box..

Nothing more than a group of neon lamp (NE2) relaxation oscillators,  
driven by a 90V "B" battery, or a string of 10x NEMA 9V units. But the slight  
differences in components lead to the appearance of a truly random sequence.  
It's a simple yet clever electronic perceptual illusion.

I received a board in from Ebay that will convert about  10 volts to 30

one I bought. 
It is almost like a DC transformer in that the higher  the input voltage 
the less current it will take to produce the same high  voltage out.


I bought a couple of these DC buck  converters a while ago too. In a drawer 
I found what may have been my first  soldered kit. Check it out it's an 
Eico EC 700 Mystifier. Random blinking  neon bulbs.

Some  NE2 neon bulbs, resistors and capacitors. Back in the day I powered 
it from  a really long narrow 90 volt 'B' battery. They aren't manufactured 
anymore.  

These inexpensive buck converters are handy for powering Vacuum  
fluorescent display (VFDs) projects too.
