Bit of an odd one for the lateral thinkers.

If you wanted to put some powder in a dish and light it, as in an old fashioned flash gun, what could you ingnite it with using say a 9v torch battery.(One of those little square ish ones with both terminals one end) Is there a cheapish electronic component that would go into melt down and preferably burst in to flames when connected to the battery?

Wire wool?

Peizo (sp?) Ignitor for remote operation?

Rod as Adam said wire wool in contact with a dead short across the P and N terminals of a charged battery = a mini sparkler, charged loose batteries that could come into contact with anything conductive = sleeping time bomb. On another point it's worth having dedicated battery cases when carrying spare batteries. Some of the old fashioned camera flash units worked on the principle of impregnated wire gauze arrangement.

I think all the remote igniters are 240v. Don't think battery would have the ampage for wire wool, but I'll try it.

Rod >>>Don't think battery would have the amperage for wire wool, but I'll try it.

The finer the grade of wire wool e.g. 0000 the easier it will combust have seen a plumbers tool holdall that toasted itself when some wire wool came into contact with a Dewalt spare battery.

I have a 9v peizo unit in the workshop, i'll have a look tomorrow

Any good?

Wouldn't the heat destroy a battery peizo unit after a couple of uses? I would ideally like to be able to use it several times at least, or be cheap enough to be disposable. That was the thinking behind some component that would self destruct.

Rod, with hindsight might be helpful to explain what you want to ignite remotely

The push button units on the mobile gas room heaters work very similar to a "battery free" spark plug or use one of the many varieties of diesel glow plugs run from a small rechargeable 12 volt lamping battery

Is your project a Heath Robertson experiment or are you researching Health and Safety issues and a dislike of using a box of matches or a lighter

Am I right in that your new project is 100% Kosher and might be subject to patent restrictions

Thanks

Just read your post again Rod.

Carefully crack and remove the glass off a 6 volt or 12 volt bulb, it would give you the same set up as one of those old fashioned hand held battery operated gas hob/oven lighters. Or you could use a bl##dy long bamboo with one of those fire lighting spills gaffer tapped on to the end of it

Thanks

P.S. Professional fireworks organisers would be using dedicated banks of remote igniters
