WARNING - This is a high-voltage device. Use caution to avoid receiving an electric shock.
This is a battery-powered high-voltage pulse igniter (spark generator) with a nominal output of 26,000 volts (26kV). The output generates a strong hot spark making it ideal for a potato gun ignition system. This improved version has a smaller body and higher frequency output voltage.
The hot spark provides reliable potato gun propellant ignition.
ACCESSORIES NOT INCLUDED - To make it work you'll need a battery holder, batteries, a switch, and some electrodes. It will work from 3 x AAA alkaline batteries in series to make 4.5 volts DC for the input. Larger batteries like AA, C, and D size can also be used, or a single rechargeable Li-Ion cell such as 18560.
ADVANTAGES COMPARED TO PUSHBUTTON PIEZO
Higher output voltage generates a hotter spark
Quieter than the clack-clack of piezo igniters
Continuous spark output while powered
SPECIFICATIONS
Nominal output voltage 28kV AC
Input 3 - 4.5V DC @ 500-950mA^
Recommended electrode gap 5mm
High output, operate less than 5 seconds at a time
Input and output wires 60mm
Body size 42L x 16W x 23H mm
CONNECTIONS
INPUT 3 - 4.5V DC red positive, white negative
OUTPUT 26kV AC white wires
NOTES
^ While it can run off 2 x AAA alkaline batteries (3VDC) the output is more reliable with 3 x AAA's (4.5 VDC).
> Residual voltage may remain when input power is disconnected. Short the output to discharge before touching.
> Do not operate without a load. If the electrodes are too far apart to create a spark it may jump internally causing damage to the unit.
ABOUT POTATO GUNS
Potato guns are NOT illegal in New Zealand but you do need a firearms license to own and use one. This applies to combustion-type potato guns, i.e. the sort that uses deodorant, hairspray, or similar gas fuel. And because they make an explosion (like the gunpowder in an ammunition round) to propel the projectile they are technically classed as a firearm and should be treated the same as when used and transported.
