FAKE PHONE RINGS
Mon, 15 Aug 2005, 11:54 amAt Busselton Repertory Club, we would like to make a modern phone "ring" ("brr-brr") on stage. We have a device that we crank to ring the bells on the old-fashioned phones.
Does anyone know how to do it? If it has to be built from a diagram or a spec, we can get access to technical people that should be able to help us. I will be in Perth in late August/early September if a personal visit will help.

In the now digital world of telephony the ring voltage has been upped to 90 volts at 25 Hz. 60 volts was the analogue value. Not that it makes that much difference, if any, for your application, but it certainly makes the old 800 series telephone with a bell ring a whole lot louder!
