Well, it cant not work! If you really want to check maplins sell a really
vheap strobe set for 14 quid. replace the strobe tube (£1.60) and replace
the resistor/capacitor trigger with a zero crossing chip... if the disc
appears still when illuminated, you have it!

It really depends on the power supply. For a small supply like an NST, i'd
use 120BPS. This means that every peak (positive and negative) you have a
bang, which maximises the power to your primary coil. If you have a larger
power supply try 240 or even 480BPS - this keeps the SG wear very low, and
will possibly give you better results (but only with a pig or MOT supply)

Well good luck!
