I'm working on a project where I'll need a little dedicated power supply. I didn't want to go and purchase one, so I did a quick little mod on an old ATX supply.
Old computer power supplies are also a great resource for ham radio transmitters, CB radios, chargers, or any other item that needs a regulated 12 volt source. Many of these older power supplies do not have an on/off switch on the unit. By tapping the green wire and any of the black wires on that connection plug that goes to the motherboard a standard switch can be wired in.
Another benefit is that these supplies have several wired 12 volt and 5 volt outputs. A custom supply with USB plugs and several cigarette-style receptacles could be constructed. So if someone needs a power supply and is a little tight on cash but has an old computer laying around, this might be a good option.
Anyhow, this is nothing too new. But I always make a little YouTube video of these projects if anyone is interested.
