You can light it again and again --> perfect for Halloween, a lot of effect on kids !

Beware however that the electrods give up to 10000 V... but very low intensity

The inverter can be found on ebay --> look for : DC High voltage Generator Inverter Electric Ignitor DIY Kit for 18650 Battery

Out of interest how precisely do you have to locate the electrodes to ensure the wick lights so reliably?

No sure, absolutely no danger...
Well ... at least I have not opened the ports, so it only works on my local network

The electrodes fire when less than one cm and when powered by a lipo 2s
With 1s, it must be very close : 3mm .. too close to work reliably.

If you increase too much the voltage you will blow the NPN transistor (I did it so I am sure !)

So finally the electrodes must not touch the wick. If they do , the light will dim and vanish.
Here is my candel before first try, you can see the electrodes (two white wires around the wick)
