| IPAC and volcano button LEDs? |
| (1/1) |
| maraxle:
Does anyone have any info on using an Ultimarc IPAC with the old Atari volcano buttons? If I wanted to do that, am I going to need the LED harness that Ultimarc sells? Also, I don't know what the voltage is on those volcano buttons. Will I need a resistor in there to make it work with it? Any help would be much appreciated. Thanks in advance! |

As I recall, those are acutally incandescent bulbs, and a straight I-PAC won't work with it. You could maybe use some type of driver circuit or you could convert the volcano's to 5V leds (or 2.1V LEDs with a resistor). |

From all the threads, it sounds like the volcano buttons have LEDs in them. What size resistor will I need to be able to use the IPAC with them? Alternatively, what are the voltage and current ratings on the LEDs? I don't have them in hand yet so I can't look and see if they're marked. |

There's a couple threads here that covered it... but there seems to be a little bit of a disagreement on the exact resistor to use. I think 330 is what you should be using. I will be doing the same as you, but have not yet done it. All I know is after researching it, I settled on 330. But who knows if I'm making a mistake........ Ray B. |

I have done this. You need to take the +5V from the i-pac and run it through a 330 resistor to the switch. There is a thread about it here, where OSCAR schools me on how to make it work. |
