a spud cannon project.
Most people around here are eggplant agricultures. one guy here developed a cannon to scarry the rabbits that eat th plants.
The cannon run by itself during th night making a BOOM each 30 min. A large Boom that is heard by 5 km all around the village.
I need advice to make one too.....to scarry the rabbits also. Spud cannons are not my speciality and i dont know many things about built. I supose there is a controller that opens a valve and give a spark. What shoud i use as a controller ?

If this is a real agriculture application, best idea is to simply go buy one. They make 'em, ya know....

Sounds like you'd need a simple solenoid valve blowing propane through a venturi to mix it with air, followed by a HV sparker shortly after,

A timer circuit for 5-10 minute intervals is not too difficult to make yourself: http://www.electroschematics.com/5963/a ... 10-minute/

Are you dyslexic? GPL is a software license. LPG is a fuel. :mrgreen:

GPL is LPG here too, same for most European countries too I think. There are a lot cheap timers on Ebay, you should take a look.

Instead producing sound you can generate a ultrasonic repeller in particular intervals of time.timer can be very simple to build
