Adding LED's to coin return buttons
HeadRusch:
I can't seem to do the search right, but if I wanted to run a couple of simple white LED's ...driven by my PC's power supply, I know I need wires, led's and I think a resistor to put in front of them.
Can you guys tell me what parts I'd need , either from happs or radio shack? I'm about to place a decent order (optical rotary sticks) from happs so if someone could direct me to what I'd need from happs, that would be great. Otherwise, if you can tell me what I'd need from Radio Shack, that would also be sweet.
I decided I didn't want to spend $20 bucks on a super-brite LED for modding your PC just to bury it in my cab to light two non-functional coin drops :)
In other words: On the cheap ;)
Generic Eric:
I know Radio shack workers aren't known to be the brightest some times, but they should be able to point you to the LED and resistors. Just tell them that you are going to use the Power supply as a source of power. I can't see happs being cheaper for this stuff. If you want model numbers, I can't help there, hopefully someone else can

Why go with LEDS? Go with 5 volt or 12 volt bulbs. Your power supply puts that out directly, and that is what is supposed to be behind there anyway. Unless I am forgetting something you shouldn't have to do any resistor kung-fu magic at all.
TazMan:
HeadRusch,
Have you thought about these guys Super Bright LEDs
They are who I used for my coin door lights.
Their 4 bulb wedge base leds come with a builtin limiting resistor and take 12v - which you can snag from the pc power supply. Plus, they're cheap. Don't know if your coin door had the sockets for the incandescent bulbs; but, if so, these snap right into those.
KevSteele:
Here's a good guide to wiring up LEDs to your PC power supply:

I actually just bought a pre-wired LED/Resistor setup that had a molex connector for PC power supplies. Here's my review:

Of course, looking at those nifty pre-socketed LED bulbs that TazMan posted about, I realize there is a better way to go. :-\
LEDs are the way to go -- with an average rated life of about 22 years, you'll never change a bulb again. :D
