Can anyone help with my flameless lighter? Answered

I'm trying to build a flameless lighter but I am an electronics n00b. I gutted a cheap clear lighter and I have a momentary switch and a spring I stretched for the heating element. the case can only fit a AAA battery but that isn't enough to heat the spring(it does get warm though). Is there a simple circuit  I can make to increase the power of the AAA or maybe a different filament i can use that wont burn out and can be used over and over?

Use a 9v camera battery they're half the length of a Aaa and a wee bit wider use either a thinner spring or a more resistive wire like nichrome or constantan, you also need to shape it in to something not unlike the top of an electric oven hob with no shorts for best results.

Try using button cell batteries as they're tiny & double the voltage per battery than AAA,downside is their low capacity, they are used in this type of lighter you can buy. Also, I have been researching the element of these lighters as I have 1 I bought but the element needs replacing & nichrome is the preferred metal to use. Hope this helps & good luck!


These lighters use a Platinum (or is it Rhodium?) catalyst in the form of wire. If you don't have either of those metals it won't work.

That's the butane jets that have a platinum elements which keeps the flame logo reliably. This is just an electronic resistive approach, though think platinum would work fine and not oxidize as fast as a spring.

Having looked at this again, it's a no-hoper. This is why lighters use petroleum: decent energy-density.

It's entirely impractical, though it would work maybe a few times every day before needing charged/batteries replaced. We did have a weird french chemical based lighter that worked with a resistive element but I have no idea how exactly since the chemicals were long dry and it was pretty much undocumented...


For the size, you can't pack enough energy in to heat an element that won't break or burn-out. Maybe 1 light, but that'd be it.

instead of the spring, a ceramic resistor MIGHT work...
