 A neon transformer can be dangerous. I made a Jacobs ladder out of one.It was hot enough to catch paper on fire. It can get hot. It can also KILL..If you do decide to use one, put some resistors in series with the HV lines.You would need to put some high value ones in there-1 megaohm or more on each side.Put a few in series so that they will not arc over.You have to remember the HV is Center tapped to gnd. So each side of the HV will arc to gnd at half the voltage. Between the two HV leads the voltage is twice as much.About 12,000 volts AC.You touch any one of those HV leads and it will kill you. Another reason for resistors.There will be RF, so watch out and EMF waves could cook some nearby computers.A spark coil might be a better bet, but you then have to build an
 interrupter circuit.Just use an old dc relay and wire it to oscillate(off and on) the other contacts go to the ignition coil to break the primary. If you can find an old MODEL T coil that would work too,''If you need any help designing it let me know.  Main thing is RFI emissions..

Bob,  Neon sign transformer and 2 lengths of coat hanger wire. Plastic pipe is optional.This is a Jacob’s Ladder.  Rick    From: dprglist-bounces at dprg.org [mailto:dprglist-bounces at dprg.org] On Behalf Of Bob Jordan

Subject: [DPRG] Spark Generator Ladder  Q: Anyone
 know how to make a high voltage low current spark generator? cheaply    When I was in high school 45 years ago I built a spark generator from a
High voltage TV transformer, two wires in a gentle V and a clear plastic pipe over itSparks climbed up the v crackling and making ozone, like Frankenstein’s lab.
  I need one of these for two days April 20-21 for a trade show.Anyone have one or know how to make a high voltage low current spark generator? Cheaply  ThxBob Jordan
