Spark generator

Recommended Posts

Hey guys

 

i need to make a spark generator hopefully using a 9v battery and a few other little components so i can make a spark hop between 2 screws in a piece of piping. i would like the spark to be almost continuous

 

any help?

 

cheers

If the intention is to be a short demonstration of spark generation, I can certainly help, but all electrical sparks generate radio interference across a very wide bandwidth. If you just want to show the effect, fine; if you want to deliberately jam radio transmissions, then 'no way, Jose!'

From what I've learned you can't really do it with a 9v battery. It takes a lot of energy to get a spark going, and to do it continuously is pretty difficult. You could try a tazer, running on a 9v but the way those normally work is that they create the spark and then need to recharge for a few seconds.

 

If you have more space than a 9V battery, you can try using a Wimshurst Generator. They create a radical, cool spark.

I didn't know that, it's pretty interesting, but I HIGHLY doubt that a 9 volt battery can jam too much signal.

It might be possible with the Ignition Coil and other components from a Moped with battery powered igniton.

 

An ignition coil (also called a spark coil) is an induction coil in an automobile's ignition system which transforms the battery's 12 volts (6 volts in some older vehicles) to the thousands of volts (20 to 30 thousand volts) needed to spark the spark plugs.

Mopeds are a type of low-powered motorcycle with pedals, designed to provide economical and relatively safe transport with minimal licensing requirements. Traditionally, mopeds are equipped with bicycle-like pedals (the source of the term, motor-pedal), but moped is sometimes applied by governments to vehicles without pedals, based on their similar engine displacement, speed, and/or power output.
