Re: Computer Monitor

There are lots of salvagable parts from  a monitor, but you are
interested in is the flyback transformer.
Attached to the side of the tube should be what looks like a suction-cup
with a thickly insulated (it's carrying that 25000V) wire leading away.
Follow the wire till it connects to a certain component, which will  be
the flyback transformer. Depending on the age of the monitor, it may have
a disc or cylinder shaped secondary coil. The disc type will be easier to
remove and use for HV apps. 
These transformers can be easily driven by any number of simple circuits,
and produce a high-frequency(~17Khz to ~20Khz I believe) HV output, much
like a very small tesla coil. 
I'm sure someone else will be able to point you towards one set of
schematics or another, but try to find on ethat uses two 2n3055
transistors and two resistors. Hook them up with two center-tapped coils
you wind onto the flyback, add ~15Vdc at a few amps....
