AC and DC power
Shape D.:
Anyone know how you would go about powering something off a wall outlet and a battery?
I'm looking to build a plug and play unit with the jakks units and want to make it use battery power or use a plug to use ac power. would I just connect both? or do I have to do something more technical for it. I'm guessing the batteries wouldnt use power if theres ac goin into the unit. but I'm not really shure.
SirPeale:
Get a 6v adapter. Measure it with a multimeter first, before connecting it! I've had a lot of adaptors, and a lot will say 7V and actually be putting out a lot more.
I cut the end off mine and soldered it to the battery leads, but I know there are other solutions.

but if I have it plugged into a wall and I have batteries in the unit will the batteries lose power while its running?
RayB:
uhhh that could be dangerous if there's power running to the same leads as the batteries.
Tailgunner:
They (whoever "they" are) make phono jacks that would work. The jack is designed with three solder tabs, one being negative (ground) with the other two being positive. One of the solder tabs connects through a set of contacts inside the plug that are normally closed, inserting the plug from the AC adapter opens them.
Your battery will connect through those internal contacts, when you plug in the AC adapter you break the normally closed connection effectively removing the battery from the circuit.
Clear as mud? ;)
