PS1 Screen LED Wiring

Post by extremesonic »

This is hopefully the final PS1 screen question I ask, but when reading the section on wiring up the LEDs, the way the process is discribed(or the way I;m reading it) has me kind of confused. I've come to 2 conclusion's on the setup and what I want to know is. A) Are either of these right?, B) if neither is right, what is the right way? and C) if both are good which one is better?(power wise)

Both are right, but parallel(Setup 1) will give you brighter LEDs. You will need to use a different resistor though. Use this calculator to get the right value.

Its the resistor used in the book, why would I need otherwise?. The calculator says I need 27.

Tell me if I used the calculator right. 5V from the PS1 regulator, 3.6V for the LED(most are, i got mine in a bag from a larger bag so i never saw), and I'd assume 20mA as well.

If i should assuem the LED volatage needed and power into them, is there anyway of me finding out

10 will give you bright LEDs but it will also get really hot really fast.

I have a 22 and its just as bright as I need and it still gets plenty hot, but it dosen't melt the glue thats holding it.

When I looked at Setup 2, it looked like he just had wires crossing each other, and I didn't look too closely. Now, stop looking at me! I said don't look at me! IF YOU KEEP LOOKING AT ME, I WILL CUT YOU!!! **Runs around laughing hysterically**

hmm well maybe i should go for a 27(the next closest one). Anyway my dads gonna try and grab a 22 or 27 form work(but he forgot today :x, and i really wanted to finish that too I have no homework, and have about 13 days to finish it and some report stuff to go with it), so hopefully tomarrow.
