Lighted PSP Mod Tutorial II (Updates and Voting)

[Llamma123]

I had a chance to make a couple updates to the PSP LED tutorial. Thanks for the feed back here on the forums to make this a bit easier to accomplish.

I did the mod twice (once on mine and once in my cousin's) and I found that if you dont use the transistor the power light will loose brightness , Also If you are using different color SMDs you need to use it or else only one color will light up, (I did one with red and blue, first tested without transistor and only red would light up, but with transistor and using one of the grounds it worked perfectly, I grounded to one of the holes near the edge) I personally would recommend using the transistor

Edit: forgot to say, that colors will be brighter If you actually use a transistor

yah i have made this as a my part time job rigth now that im in for my apprenticeship as a auto mechanic so little spending money so. So far ive gone through maybe 10 or more psps having the led mod and some painting their rear faceplate

never even tried to use a resistor

only thing was llamma as you can remember you have mentioned something about me using a 100ohms resistor for the 4 leds instead of 50 yes that lasted about a month and the resistor just melted it self

ok so im new to led wiring and lighting and all that stuff, so i dont know were to wire everything. can u help me out?

[CrossEyedLarry]

Im about to do this mod and i just have a quick question:

What resistor do i use if i want to use a red LED?

Thx in Advanced

[aznhavok]

the rating between the red and blue doesnt differ that much so you are safe to follow llamma's tutorial

[CrossEyedLarry]

Thx for the help.

Just one more quick question:

If you want to light up both the triggers and the d-pad and the buttons ( X, O [] ^), would you use the same positive connection point for all of the LEDs?

Thx

[aznhavok]

yes you do so combine all leads then solder your resistor on then solder that to your board

[skullmaster]

Are all surface mount leds the same?

[aznhavok]

can you be more specific when you ask the same

Seriously guys your question will be answered the way that you want if first of all you give the rigth question

[skullmaster]

When I say the same I mean that do they run the same voltage and are they the same size?

[skullmaster]

Do you need a resistor for any color led or just the blue ones

[skullmaster]

So where do you sodder the lights to. Like where the power leds on that circut board.

Another question how do you sodder on a circut board?

[skullmaster]

Should I use a transistor or a risistor?

[aznhavok]

Skullmaster just a note if you dont want to get banned of a forum, always try to have wat you want to say in one post, coz if you only know that sometimes forum cannot sustain its availability through advertisement especially people that loads the forum's server with multiple post like that

Ok to your question generally LEDs can run from 2.0 -12 volts but you'll only be working with 12 volts LEDs when it functions are more than just lighting up a space. so from smt's to your regular 3.5mm led they are from 2.0 to 3.5 volts. Keep in my besides your voltage you also have to deal with the amperage capacity of the LED which you may also have heard about ma-milli amps now this can run from 10ma - 30 ma. If you will do a experiment like testing LEDs if you would try to run a single led with 5 volts you'll probably see it quickly flash and smoke reason well I'll let you decide. Now run 2 LEDs on 5 volts theres 2 ways that you can run this on is you connect the positive lead of your first led to the negative lead of your second led then have the second led's positive connect to your positive lead source and connect the first led's negative lead to the negative lead source, with this you are pretty much running a single led so the result you should know if you have done the single LED. the second way is have both positve leads of you leds joined and same with negative then attach that to your source, you will then ask why it didnt had the affect like the first way. but it does get really hot. Now comes in the most important part of electrical design your resistors think of this as a limiter like your parents that says no you cant have that, or that much or nothing at all. it controls the flow of amount of energy that goes through your LEDs

I hope you can understand what I've written here and I would suggest that you try things dont be scared you'll only learn through your mistakes.
