Screen Surgery

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

I'm using a 10 ohm resistor, is there something I should know about?

The LEDs burn out quickly. You should use a ~30ohm resistor.

I thought the only way to burn out led's was to apply to much voltage. I guess I should go out and get another one. Thanks for telling me. I've already put it through 3 99 stock tests and playing it myself.

EDIT: Ok, I found a 56 ohm resistor, still works the same way. I should be safe now then.

With a working screen? It worked just fine for me.

With a 10ohm resistor, it is getting too much voltage. Not enough to make them spontaneously burn out, but enough that it slowly kills them.

Eurddrue: It works, but only for a while. See my reply right there ^

you are supposed to put a resistor for each LED.

Not according to bens book, it says you can hook up one to all 4.

It depends on whether you hook them up in parallel or in series.

Also, just because Ben published a book, doesn't mean it's the know-all, end-all of portablizing.

Of course, but an led resistor value seems to be something simple enough to permanently figure out. (apparently not though)

One 10-ohm resistor has always worked fine for me. I don't drench my screen in hotglue, so replacing LEDs is an option.

it all depends on how many leds

Not if you use 5v LEDs :| I'm pretty sure mine are.
