Electronic Firecracker
« on: August 23, 2018, 06:09:42 pm »
Hi,

It is getting near for me to start working on Halloween props.  One thing that has always interested me is these electronic firecrackers that you can get from frightprops.  They are pretty expensive for what the are.  They sound to me like a Capacitor being discharged very quickly.  I am not sure if that is really what is going on so I thought maybe you guys might have an idea.  I would like to make a few though I am not that great at creating electronic circuits.

Any ideas?

thanks,
Pete

Sounds like a high voltage/ high current discharge.  I guess an inverter/voltage multiplier ladder with sufficient low ESR output capacitance that when the spark gap gets ionised the resulting discharge current is very high and very short.  Certainly wouldn't want to be getting fingers inside those things.
