Adding LED's to coin return buttons
« on: May 24, 2003, 08:42:55 pm »
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 ;)

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.

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.

Here's a good guide to wiring up LEDs to your PC power supply:

http://www.dansdata.com/caselight.htm

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

http://users.adelphia.net/~kevsteele/mame/lazer.html

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

LEDs?  You don't need to buy too many things.  You will have to know what the power supply voltage is.

If you don't want to do the math here are some "safe" values that'll work.  They're based on a 20mA, 2Volt LED.

5V power supply - 200 Ohm 1/4 watt resistors, LEDs
12V power supply - 510 Ohm 1/4 watt resistors, LEDs

Here's another tutorial page...

Why go with LEDS? ...and that is what is supposed to be behind there anyway.

Paigeoliver is going loco.  Happ, themselves make wedge based LEDs to replace those incandescent bulbs so I would hardly say that you are not inteded to put LEDs behind your coindoor.  That said you just have to ask yourself, "Would I rather change bulbs once every two to six months or once every ten to twenty years?"

ha.. on the pun... but I actually dealt with a RS employeed who didn't know what LED's were ... nor "light emmitting diodes"... had to call the manager over... they only know how to sell crappy cell phone plans now (and they don't really know how to do that)

Since 20 years ago, LED technology was in its infancy stage, it only makes sense for them to use incandescant bulbs.

However, it's just a smart thing to do to use LED nowadays.  Initially more expensive, you'll save money since most are rated for a life of >10 years.  Power savings as well, but that's secondary.  You also get the added benefit of nearly no heat given off.

To each their own, really, but I'm going to retrofit with LEDs on my coin door.  The best part is I don't have to change anything, just pop a bulb in.

nb: wouldn't it be a good idea to use a high mcd red LED, as opposed to a white one?  They're cheaper, and most rejects are red anyway.

I used 1 white superbright led with a resistor for each coin door light.  It runs off the 5V of my PC powersupply. They installed fairly easily and they look perfect from the outside.

Well the price doesn't seem too bad, which one should I pick? The T 1-3/4 AND T 3-1/4 WEDGE BASE LED,  the T-1 3/4
WEDGE BASE LED or the T-3 1/4 WEDGE BASE LED? I have a D&D 4player cab...

The size I used was T 3 1/4 wedge base.
I thought I remember seeing the Happ's price being like over $10.00 / bulb or something like that...  I checked - I guess if you are going to use Red, the price isn't that bad $3.20; but, the white ones are $14.25.

10 bucks? An LED from superbrightled's is like 2 bucks tops, add a cheap radiocrap resistor..talking 3 bucks at the most.

I agree "Oh Frosti One"  actually the ones I mentioned near the start of this thread have the limiting resistor built-in- and are less than $3.00  :o

How do you think the red wedge offered by happs would look for the red coin return button's? I mean would it lite it up enough you think?

I don't know for certain; but, I had asked my rep at Happ's for the specs on their LEDs and she didn't have any.  I would guess since they list them as replacement for the illuminated push buttons they may not work that great for the coin door.  I know I have a Happ door and added the 4 bulb wedge base leds (from SuperBrightLeds) to each coin return button and that did the trick nicely.  I took some pix of them tonight - but I left my card reader at the office - so I'll post em tomorrow.    

<Edit> Here's the pic.  Keep in mind these are the default yellow plastic coin return buttons from Happ.  But with the green 4 bulb led, it helps keep my green theme goin'

Well, I don't know about you guys, but my 1983 Centipede coin door does not use wedge base bulbs.   These are cylindrical base, twist-in bulbs.

I was thinking of using the original incandescent bulbs, and somehow wire them through a transformer.

The bulbs seem to read: 6.3 V  0.25 A    does this sound right?

Justin,

Are you talking about bayonet style bulbs?

If so, SuperBright carries those also in 6v or 12v.

Derek, I went the easy route and bought the 12v bulbs from them - since you have either 5v or 12v from the pc power supply.
Does that help?

Yep, they do.  Are you looking at wedge based or bayonet nbased bulbs?  Is this a Happ coin door or a re-furb from an old cab?

Go scope out the links I put to superbright's website in this thread, there's one for wedge bas and one for bayonet type bulbs.  Does you current door have bulbs?  If so, just match to the pix at their website.  If not, does your door have sockets for the bulbs?  If so,  do you have a pix of the socket you can send my way?

Soon as I get my digital camera working I'll get some pics. Um i just took of the light and socket. Its pretty big with two connectors (i think .187 female connectors) per light. The casing comes apart from the light, there used to be writing but now its not readable. Ill look at work at your page to try to decide which one I have.

edit* The bulb just slides off the casing with a fin like thing at the end.

Fin like...hmmmmm.... sounds like wedge base bulbs to me.

Super Bright LEDs

That's what 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.
