| Super bright LED driver board for I-PAC |

Oscar, you are welcome! Say, some day I must get the same digicam you got - you always've the niecest picture of glowing things! (monitors, LED-buttons...) :D You are the very first person I've ever seen making colored circuit-diagrams ;D Very good idea, you never know how often you'll need additional 5V-lines! Oops, I mean LED-lines, on first sight I oversaw the multi-resistor! As I'll have more then one controlpanel, I decided to include the resistor for the LED (these are the ones directly for the screwing-terminal) on the panels itself, as I might choose different LED-types. |

Nice meeting, we're at least three here from the good ol' LED-buttons-thread, anyone wanna a beer? :D (I'm just happy 'cause my cab is finally able to play ;D ) |

:o OOPS... I havent used my I-PAC LEDs for a while, just plugged the harness back in to check it out, and the LEDS don't blink anymore! :'( Under Windows 2000, when I go to play a game that uses start button LEDs (Pac-Man etc) and "insert coins," the LED harness lights do not blink. However, I can see the keyboard LEDs blinking. The strange thing is, when I press Caps Lock, Num Lock etc, the LEDs on the harness light up (steadily with no blink) as expected. This works whether I am in a game or not. Also, the problem arises in 2 different versions of Mame. Hey guys, please let me know if this is an issue you are aware of, and how I might fix it. The LEDs used to work properly, I'm not sure what could have caused them to stop. BTW, I'm having the same problems whether I use the LED driver board or just the LED harness with the original LEDs installed... PS, I already emailed Andy, but he's usually a bit busy... Thanks |

That's awesome Oscar. I had pretty much given up on the whole LED thing as I was getting far too carried away with it (lights under every button) Carsten can confirm this. I think I could even make something from that write up and I have no idea about electrics. The desire for lights under the buttons is slowly returning..... Cheers -cdbrown |

Try the other connection (and don't forget the jumper-setting ;)) I bet you know, but at some point they added (at least in MAME32) an option to disable the led-blinking-feature. Who on earth would do this? ??? Anyway, also might be worth a checking. As the LED-harness does work when pressing NUM-lock,... the I-Pac should be ok I guess. |
