computer relay
I could use some help with determining where I need to look -- a need
a relay that will enable a PC to power up (and then off) an external amplifier. If you are wondering, this is to replace a church carillon with a PC that has a timed program to play MP3 files. |

Here is just the first one the Google returned for: usb relay http://www.j-works.com/jsb281.html There are relays controlled by serial, parallel, USB, BlueTooth, etc. etc. etc. There is also the X10 stuff. Wireless and inexpensive. |

Oh sure mp3 can sound alright... but a real CARILLION! Not 'just' an organ? What a great opportunity for a "steampunk" project: to drive that carillion w/PLC controllers & stepper motors... |

Or at least the one with little metal bars which were amplified for the speakers. Did they do pitch shifting (1/2, 1/4?) or use sub-harmonics to get the low bell-sounding tones? OTOH there is a company out there that is making digital "ranks" for real pipe organs. They apparently use terriffic over- sampled waveforms and they even use sensors on the real pipes to keep the electronic ranks tracking in tune (with natural changes due to temperature, humiditiy, etc.) One was recently demonstrated to me by an old-school organist (who also has specified many pipe organ installations around the world). The pipe ranks were impressive enough, but even the chimes were impossible to tell from the real thing. And I would have bet my life that the Zimbelstern was real, but it was also "Memorex"! I should try to discover what drivers they used. http://www.rcrowley.com/Rieger/SSDAReiger2.htm http://walkertechnical.com/ http://walkertheatreorgan.com/ |

I believe Guilderfluke and Company still makes commercial microprocessor controller for carillons. No need to hack up a bunch of ladder logic to play Rock of Ages. --scott -- "C'est un Nagra.

Thanks for all your help. Our current "carillon" is basically an
eight-track player! I'm trying to avoid an amp that is on all the time. |

Call Gilderfluke and Company and order an electronic carillon. Easy to program different tunes into, sounds better than you'd expect even if it doesn't sound much like the real thing, and not too expensive. --scott -- "C'est un Nagra.
