Help LED modding a PSONE Screen

[IRisH360]

Ok so ive been reading ben's book and the forums and it looks like the consensus is to use 4 LED's with seperate resistors on each right? Now is it 33 ohm resistor on each or is it a 10 ohm resistor on each? and which LED is better? I saw someone suggest a different LED than the one in ben's book, but i cant find the post. Thanks for the help

The value of each resistor will change based on your source voltage. Here is a nifty calculator for calculating just that.

You will need to look up the specs for the specific LED you are using to use that calculator. As far as which LEDs to use, I suggest just searching for some that have a high mcd rating at a wide angle or ones that have a high lumen per watt rating. Digikey is a good place to start looking for those.

would these LED's be too much? I mean they'd come with the resistors for the 5v source of the screen regulator?

Yep. I would imagine those would be fine. I used similar ebay LEDs for my project and it was plenty bright. Granted I used six.

on what kind of screen?? and why? and what array?

On a PSone screen, to make it brighter, and I put them in three pairs.
