| NovaGemCDR™ Coin Drop Replacement Pushbutton LED Replacement? |
| << < (2/3) > >> |
| RandyT:
Sorry, I saw the email, meant to reply, got pulled off task and lost track of it. The problem is that the LED is not a standard LED. It's the equal to 5 standard LED's. It's also not easily user replaceable (normally, it's not necessary to replace it) The best would be to return it for repair. I'll send you an email with details. RandyT |

I sent this question to GroovyGameGear just now but I thought I'd post here just in case any of you know the answre to this as well: I wonder about powering the led inside it. The site say it can be wired up to 5 volt directly, but does that mean the correct resistor is already in place inside the NovaGemCDR? I also wonder if I could wire this up to the LED pins on my IPac controller as they have some headers pins to control caps-lock leds and such - it would be an ideal place for me to wire the coin door led to if I could. Here is some info about the Ipac and it say I need a 220 ohm resistor for each led connected to it: http://www.ultimarc.com/ipac2.html Hope you can help. |

Since your project only has one CDR, you can use a USB power tap cable like this one or connect to the power supply molex connector. Scott |

Thank you for the reply. I also got a reply from GroovyGameGear saying I should not use the led harness of the Ipac (it gets power from USB or PS2 so I dont know how good it is to draw 100mAh from that). I will hook this up to a molex from the psu then, just have to be 100% sure I dont hook it up to 12volt :) |

With a powered hub port, you can run up to 500ma per port IIRC. When you tap into that molex, just be sure to avoid the yellow wire. ;D If you have a spare USB cable, you can make your own power tap like the one pictured in my earlier post and you'll definitely avoid the 12v.
