I've been following the other posts... Love the can-do approach. And updoots for the anon contribution to society. I've tinkered with a lot of things, but generally stick to simple mechanics or basic chemistry, non-electric. But this project might inspire me to level up!

Question: why do you want to use sparks to measure your output when you could hook up a voltometer of some type? Hooking it up to a toaster comes to mind for morning toast, or other random appliances like a space heater. A long time ago I used a stationary bike with a power output meter on it... old exercise equipment is not hard to come by.
