Just building a plasma speaker, or singing arcs, whatever....took me about 3 hours but prototyping it took a couple of days. the power output was low but i powered it by a 12 volt LiPo battery. what you expect jk, my circuit can handle up to 30 volts. ill show in a later video. used a NE555 and a flyback transformer.
