Interchanging Between Wall/Battery Power

XFactor · Post by **XFactor** » Wed Mar 15, 2006 7:08 am

I read daguuy's guide explaining how I would set up the wiring for my portable; however, I am confused as to how I would wire a wall power input into the unit. Is there any guide to explain how to do this?

Also, I am thinking of setting up a headphone jack so i don't waste as much battery power. I saw an explanation on daguuy's website as well but i'm wondering how hard both of these additions would be...

About the headphone thing, I've also wondered how do wire the headphone jack to the PSOne screen. I suck horribly at tracing, so instead of making a topic, I'll just post here.

Anyone know which pads are the 4 headphone things? That's the headphone/AV combo jack from the Sony PSOne screen.

i'm not too sure about the headphone thing, i'll have to find that out. here's the battery/wall thing:

it's really simple

Actually, on the battery/wall switch, I just hooked up the positive lines.

1 2 3
4 5 6

So if those were the pins on the switch, I hooked the wall power to 1 and 4, hooked the battery power to 3 and 6 and then hooked the n64/screen/everythingelse to 2 and 5. Its easier this way if you aren't very good at soldering + and - wires that close together. I just did mine this way so I didnt have so many ground wires that werent needed.

but with those methods doesn't it turn off when you switch between battery and wall power? Why don't you use the diode method?

im sure theyd appreciate if you explained that one a bit more

eh, i'm just the critic....let someone else explain it!

or you can just put a diode on the positive terminal of the battery before the regulator and put another diode from the wall input (assuming it's a DC input) to the input of the regulator. When you plug in the wall power, you can unplug the battery and nothing will be interrupted. Use schottky diodes if you can, you'll get better battery life because there will be a lower voltage drop over the schottky diode as opposed to a silicon diode and your regulator will take longer to drop out.
