Adding a recharging circuit to a LED hula hoop
I'm just completing a LED hula hoop. I was hoping to eventually retrofit it to add a detachable solar recharging circuit.
What I'm wondering is:
What's the best way to splice the recharging circuit into the already existing LED circuit?
The current setup is two batteries in series, connected to 9 LEDs and resistors in parallel. The batteries and LEDs are separated by a switch. It's loosely based on this ible:
I plan to add the capability to plug the hulahoop into a solar recharger box during the day so it can glow all night long! I'd like to set it up so there is a small recharging 'port', near the batteries, that can be plugged into the recharging box.
Any ideas or tips?
