DIY Super Joule Ringer 2.0 "Tuned"!!! Parts common! 16-20w!! 15.00 cost! lights 6-9 LEDs
This is another variation that’s a little cheaper to build and will give just a bit more light, but does not have charging. So, this is a Super Joule Ringer 2.0, but Tuned. I had to change the caps a little so I thought I’d show both options depending on what you may be looking for. I hope these two help, Thanks PB
