hi, i am pretty new with electronics, and i cant find any simple boost converter circuts on the enternet. i would like to make the circut THE MOST SIMPLE i can, with the fewest possible parts. for a power source, i have 9v-1w. for the output power, i would like to send a thin spark from 1 electrode to the other about 1/8"-1/4" apart as a substitute as a spark plug. schematics, diagrams, photos, links all would be helpful, but keep in mind that about all i can do is solder, and go to raioshack. thanks, Ben edit: here is a simple curcut i found(http://en.wikipedia.org/wiki/File:Boost_circuit.png), and i understand everything but the switch. how would i get a switch that switches the flow of electricity off-on that fast?
