N64 Screen Help

Post by rodogg78 »

I have an Emerson 7" screen with composite inputs but takes 9.5v to operate. I am not worried about the size of my handheld but wonder if it would be better to use a PS1 screen(or something comparable)? I know most things are just preferences. I planned on using a Polymer Li-Ion Battery: 7.4V 5000 mAh. Since my screen is 9.5v then I guess I would have to use a battery with 9.5v. The Emerson screen plays great but if I have to go another route then I will. Sorry for all the questions but I am new to this. Maybe I can help somebody once I get one built!ha ha

You might be able to see if your screen can use a smaller voltage, like 8 or 8.5.

or stick with 9 volts but use a regulator.

Someone verify this post because i've never built a portable in my life.

The best thing you could do would be to open up the screen and follow the traces from the power input jack. Hopefully it goes to a regulator somewhere. If it does, you could google that particular regulator and see what its input voltage requirements actually are. (9.5v seems to be such an odd voltage, I'd be willing to bet there's a regulator in there and Emerson picked 9.5v so that they can say "only use this product with an official Emerson power adapter")

Also, yes, a PSOne screen is really easy to work with, and they can be had fairly inexpensively.

Fight MS Paint abominations! If you don't have a camera, go here, and pick something 3 megapixels or higher.

He right. 9.5 for a screen?

Very Odd Indeed!

Thanks jdmlight and gamax92! Well the reason I said 9.5v is because it says on the side of the screen where the power supply plugs in. You are probably right about the regulator. I will trace and see if it has a regulator. Hopefully it does and I can use lower voltage. Thanks again!
