Ignition idea

[john bunsenburner]

Ok i am not sure if any of you have done this if so forget about this thread. I am a pneumatics guy and will stay oen so please dont ask me too many specific questions, it is jsut a suggestion on which you can develop:

I think you all know what a lighter is. But i am not sur eif you noticed there are two tyxped, those where you have to spin a little wheel that makes a spark and those where you just press a botton to make the fire. I took latter apart and found the igniter which makes a little spark, it ignites gas and gasoline very nicely after one or two goes. I use it light stuff now where i dont have the lighter any more. Maybe it could be used as a cheep way of igniting spray and prays seeign how darn simple it is...

Good for minis' Where have you been hiding John?

[john bunsenburner]

sorry my brain is full of french and german homework. What do you mean hiding?

[jackssmirkingrevenge]

Er... this is the same piezo ignitor that you find in lots of combustions, like this oneI had made.

[john bunsenburner]

Ok i did not know that, sorry for the annoyance...

Or, get the fuel source and ignition system from the lighter;

Omit the 35mm film canister, it's for something else. Run the fuel hose into the chamber. Wire the two piezo wires to your spark electrodes. The lighter's trigger is used to fuel and fire the cannon, on separate pulls of the trigger.

What i was suggesting was more like if it is sunday any you are deserate for a cannon...

Which is the day of the week I made the fuel + ignition system from the long handled piezo lighter

[john bunsenburner]

sorry i am thinking too swiss as in: dont vacume clean on sunday they might charge you with go knows what, just like dont blow your nose while driving, a horrible crime indeed...Ok sorry for bringing somethign old up...

Anothe rlittle question: how long will the igniter spark before the battery runs low?I sparked about 1000times in the past few days, how long will it still last?

[psycix]

Battery? What battery?
You mean those little "click" ones out of a lighter?
They dont have a battery. They simply wear out or break down on one day.

[john bunsenburner]

Well either there is a smll nuclear reactor in the bottom of there is a battery, electricity cant coem from no where and it is clearly nad electric spark and no tlike in a mg strip lighter ehere it is burning material.

Yes, there is a small thermonuclear device in that $5 lighter. It's amazing what scientists can do with nanotechnology.


There are many materials that, when struck, create a voltage. The energy source is whatever hit it. In a piezo sparker the energy source is your finger. No batteries, no chemicals, no internal energy source. Look up "piezo" in wikipedia.

[john bunsenburner]

Then the crystal or uranium( ) has to run our, or does it last for ever?

[TurboSuper]

The good ones will last for a while before they run out. Probably longer than you'll maintain an interest in spudding. And then you can just replace them. No biggie.
