Simple circuit to create a spark

rictrajano
rictrajano over 1 year ago

Hello,

My small torch spark mechanism is broken and I was wondering if I could create a spark with an electronic circuit. I use this torches daily and it's been the 3rd that got broken and you can't really buy spare parts for these.

I'm not sure where to start on how to create a spark with an electronic circuit (although sometimes they happen spontaneously in some of my projects Smiley)
The ark will need to be 3mm (maybe less but I'd like to point to 3mm)

Thanks in advance for your help

    Why not just try and fix the small torch spark mechanism? This spark lighter always works.

    One way is to get a nice sized inductor (like an industrial dc motor field coil) and connect to dc to charge. Lift the wire after a few seconds and enjoy the fireworks. Or you can get a piezoelectric…

    Thanks everybody for you suggestion. I ended up finding what I was looking for:

    https://www.aliexpress.com/item/1005004606111441.html?spm=a2g0o.order_list.order_list_main.5.51471802WA4pxg


    This will work perfectly. I'll 3d print a case and will look great.
    I just need to come up with the mechanism for the arc to activate just for a short time, but I think that will be the easiest part.

    Thanks for your help

    I believe that's the same one. If size factor wasn't an issue I could buy the components and build my own pcb but I would have to make it bigger and buying the components individually would certainly end being more expensive.

    Thanks for the link
