Topic: battery or wall power (Read 326 times) previous topic - next topic

I have built a project that will run off an attached 12v battery. If I wanted to add the ability to power it off the mains instead, I thought of just adding diodes on the positive, but I was wondering if there was anything else I should do? Do I need a switching power supply? does anyone have a schematic?

Thanks

Of the mains!!!

You need a mains 12V DC adapter, there are lots about for cheap.
