My ignitor box

[GlowinPontiac]

Today i decided to take some of the random electronics parts i had laying around and build an electronic igniton system.

 

It's powered by a 12v 12ah sealed rechargeable battery and two switches that must both be closed before firing along with status led's to indicate power/armed/firing conditons.

 

when the unit is powered through a plug on the bottom a green led in the bottom center is lit indicating that it is connected to the battery. The leads going to the device being ignited come off two screw terminals on the back.

when the first momentary toggle switch is thrown an orange led lights and a high pitched tone sounds from the speaker showing that the device is armed. then the pushbutton is pressed while holding the toggle switch on and a red led lights and the device is ignited.

 

i had hoped to make use of a keyswitch as an additional safety but due to the extremely small size of the project box i had it just wouldnt fit.

 

well this is my first igniton box so have a look at my pics and let me know what you think and what i could do to make my next one better.

 

This box can be built in a few hours with basic tools and for under 20 dollars if you already have a battery.

Looks good. Motorcycle batteries are good choices because they are much lighter than car batteries. The only advice I can give you is when you move up to multiple cue firing systems don't forget the diodes. I had to rewire an entire panel and every rail we had when we realized the ground was backfeeding through other cues. 300 in the field and 100 on the firing panel.
