From the parts list, the circuit you built looks like a stun gun.
Instead of the discharge cap approach, drive the transformer with an
LM 555. The resulting control over frequency and duty cycle will allow
you to select a more agreeable stimuli.
If you need more voltage, given that there is no return contact, wire
two or more transformers with their primaries in parallel and
secondaries in series. Remember to take one side of the secondary side
to common earth.
You could also try a eady made ion generator ... 12 volt model for
If you simply want tactile feedback, a piezo element would do the job.
