World's sketchiest Nixie tube power supply?

This looks dangerous: http://www.ebay.com/itm/311909180288

This is wrong on many levels. I wouldn't be surprised if the interior was a half-wave rectifier and a capacitor. 

How do you even limit the current? It says "IN-12 IN-18", yet there is no resistor outside while IN-18 requires twice the current. I think it is just fixed with a resistor inside to provide 2,5mA at 130V.

Not even Chinese would come up with so bad invention.

Looks like a 240vac to 110vac electric shaver supply with the shaver plug cut off!

The sad thing is that one could totally fit a proper Nixie power supply in there, using for example a TaylorEdge module (they are tiny!) coupled to a reasonable 12V supply. Jens

At least this supply appears to be isolated; without schematics it's hard to be sure. You can try to do leakage tests between the output(s) and ground, but that requires care if the output is also grounded. This particular supply has 2 prongs, so I would guess it's ungrounded.

This is one of the devices that should be bought and then sent to  Dave from the EEV-Blog.

Then he maybe could make a 2nd part of this https://www.youtube.com/watch?v=f14nv3uf2ik

Another option would be that Big Clive guy - He'd happily tear it down (and likely set it on fire) - Both are characters :)
