LED Coin Door Lighting

[Spawn2k]

Hi,
I know the X-arcade coin door uses a 5v 1a wall wart with a resistor to power an led. I would like to do the same with two leds for two slots.
I have some basic knowledge on how to do this but if someone has already done this... can i copy your setup?
What wall wart, leds, resistors are you using?

Would this work? Should i use something bigger than 5mm?

2 1/4W resistors with leds wired in parallel.

Also, why do some people say to put the resistor on the negative end and others on the positive end? Wouldn't it always be on the positive end, before the led, because your limiting current going into the led?

It doesn't matter if you put the resistor before the anode or cathode of the led. As long as its in  series, it will do its job.
The 500mA psu will be plenty fine for the two leds.
Doing two leds will be pretty much the same setup as the xarcade's one but just doubled.
Each led will have its resistor in series with it and then parallel to each other in respect to the power.

50 ohm resistors should do fine.

Here's a little bit of reading on figuring for the correct resistors.

You did notice that this LED changes colors every two seconds from red to green to blue, right?

Could cause an odd lighting effect, depending on the color of the coin return buttons.

I've seen RGB behind various colors of plastic.

They all look like crap until you see the same color shining through the plastic. Red shining on red plastic looks good, but all other colors look like crap. Green shining on green plastic looks good, etc.....

I agree, the changing light effect behind the coin reject will at best, go  unnoticed and worst, may look like crap.

You guys are awesome! Thanks for all the help!

I have a thread in here where I used RGB lighting to illuminate the coin door reject button with a yellow happ reject button, and I got good results with the color.  It wasn't perfect, but the yellow tint only really affected some of the colors.  I can see how a green, red, or blue button would not react well to RGB, but the yellow one is not too bad.  Of course I had a very bright LED setup too, which might make a huge difference.

This worried me. So i hooked up a color changing led strip to the coin. I uploaded some videos on youtube with the results. I used flashing to cycle the colors. If you want to see a particular color just pause the video. The inserts i have are yellow. Still look pretty good though

Lights on - flashing

Lights off - fading

The pics I posted of my results are found in this thread: http://forum.arcadecontrols.com/index.php/topic,141222.msg1461886.html#msg1461886

Similar results, and not all that bad.  I was even able to get a pretty good "white" despite the yellow tint.
