that's just 0V and not a very low impedance one at that. it would be mostly useless for EMI earthing. you will just make a bigger antenna>>1732519

until it's done. you have to tune the process in your own lab which depends on the boards themselves, copper thickness, etc. usually on the order of 10 minutes tho
if you use H2O2 + HCl in a glass dish instead, you can watch the process better and it's also a bit faster. also you never have to buy more, just aerate the solution and it's ready for round n+1

photodiodes make decent light sensors. you have to change the current around a bit. PV solar cells are just great big photodiodes

SSTV is just an FM encoding standard for video
shorter version: it was basically a CRT in reverse. like core memory, the general idea was to push some energy into something in a controlled fashion and measure its response
