I'm looking for a way to ignite butane/propane almost remotely or by button. Basically, I would like to make a spark generator. I've looked into piezos but they can be hard to press down. I'm looking for something that I can attack to a softer button. I've seen negative ion generators and ignition coils with 555's but I would like to know which would be more reliable. The ion generator would be cheaper, smaller and lighter but is it as reliable as a ignition coil? Also, if there is an easier/cheaper way, please point me in the direction of such device. Any and all feedback or suggestions are greatly appreciated. Thanks.
