Help with a wireless fireworks igniter and other functions withing it
My name is Glenn and I'm new here. Last year I built a 10 cue fireworks igniter. It was really simple and straight forward. This year I disassembled it and am trying to build a wireless RF igniter. Question 1: I want to make it a 48 channel igniter but all I can find is 15 channel boards, does anyone know how I can overcome this issue? Question 2: I'm using a 12V DC lead acid rechargeable battery and would like to add an internal battery charger with a red charging light and a green charge complete light. I'm definitely electronically challenged so I have no idea how to accomplish this, can someone help? And finally, Question 3: I would like to also add in internal continuity tester but once again, I have no idea how to do it without setting off the firework it's attached to. If someone could help me I'd certainly appreciate it, thanks for reading and I hope everyone has a blessed day.
