Adding LED's to coin return buttons

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?"

All my games are twenty years old, so I am always speaking from a point of view of what they did back then.

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)

didn't someone have a link for 3 buck high intensity LED's online?
