--- Quote from: paigeoliver on February 17, 2004, 01:46:48 am ---PC power supply is EASY to use, even if you keep your PC inside the case. I powered my Happs serial interface board off a PC power supply, all I had to do was run two wires out of the back of the PC's case. If this thing is going in a cabinet then that should not be an issue at all. --- End quote --- I started to post essentially the same thing. If you don't want to cut up a disk drive power lead from your power supply, go to radio shack and buy an disk drive power extension cord and cut the end off it. Splice your wires to that and just plug it into your power supply. -S |

I have 6V lights in my CP and coin door and I use a switchable wall wart adaptor set to 6V to power them. Works excellent. Only now I think I want more powerful bulbs, which makes my power source choice a lucky one because I can just move the switch on the adaptor to the voltage I decide to go with. Kinda nice. Plus, it's completely unrelated to any other power/computing source in the cabinet and that makes me feel a little safer. Whatever gets you through the night. :) |

Thanks to all who replied so far (what a great board). I have a few additional questions: StephenH, that was an excellent description of how this stuff works. So Stephen (or anyone) , If I follow StephenH through, the apapter I was able to find says: Input: 120VAC 60HZ 16W Output: 12VDC 1000 mA I could therefore power 10 12V bulbs if each only required 100 mA of juice... right. Is the math that simple? Does anyone know how many mA the 14V lamp takes on the Happ Over/Under door (#161 14V light bulb) ? mushmouth: Great idea. I think I'll go with the adapter as I found one in my junk sopare parts pile... :-) I am a little cautious of working on the computer as I have already destroyed a good pair of speakers and serial cable while hacking... :-) Garry |

Is the math that simple? Yes, technicially, but it is not good to overload to the max. I would say 8 or 9 is probably a safer bet. Does anyone know how many mA the 14V lamp takes on the Happ Over/Under door (#161 14V light bulb) ? from http://donsbulbs.com/cgi-bin/r/b.pl/161.html, it says they require .19a or 190ma. mushmouth: Great idea.
