I searched the threads, but, because I am new, I am not sure what I am looking for, so I apologize if this is already covered.
Here is my situation. I have a slot machine whose motherboard requires constant power. In casinos, the slot machines are never turned off, but for home use, I want to be able to turn the slot on an off. The MB was not designed for this use, and the battery drains, erasing all settings.
The motherboard is set to take 2 AA batteries to keep the charge, but these drain quickly. Inside the slot machine is an outlet with constant power, regardless of the on/off state of the machine.
What I would like to do is...
Insert 2 rechargeable AA batteries, connected to an AC power supply, plugged into the constant power. I'd like these to charge to full when power is available (trickle charge?), as well as provide power to the MB. In the event of a power failure, i'd like the MB to draw power from the batteries.
I have created small LED circuits, so I think I can do it, but I have no idea what the circuitry required is. Can anyone help?
