G'day.

There is an old thread about this subject but it wasn't much help to me.

I want a Telephone Ringer to make a real phone ring on the stage in live theatre.

I can't find anything in Australia.

I did find this and it would do the job if I can't find any thing else.

Any body have any other ideas?

Thanks.

Are you sure the 'Lighting

Are you sure the 'Lighting Operator' tag is appropriate? Seems more like a sound question to me... Why does it have to make a real phone ring? Why not just pre-record? ... You could always try looking up books that offer some suggestions on making your own phone - though I can't think of any off the top of my head, I'm sure there's something out there somewhere.

oops.

Yeap, sorry, new here, I am the Lighting Operator.

I also know about other electronic stuff so I got this job. I was hoping to find something in Oz.

We would like the phone in the stage to ring with a press button off stage rather than have the sound guy play something through the house PA.

There were kits to do this back in the mid 90s but they are no longer available.

I can get a photocopy of the article for $10 & build it myself & it looks like that is what I'll have to do.

The telephone test equipment people have stuff but it has too many functions & would cost more than the one from the US.

I seem to recollect that Don also had/has a collection of phones to suit a variety of situations and eras.

phone ringer

Hi Cliff, another way to do it, and a way to make sure it is on cue, would be to hook it into the theatre phone line and get someone back stage with a mobile to ring the number. Hope you get what you are looking for.

if i recall correctly, you

if i recall correctly, you can do this quite easily. Curtin Uni had one and so did Wanneroo Rep. you just make an old phone ring by connecting certain wires to a battery and a switch.

G'day.

It needs more than a battery.

It needs about 50 to 70 volts AC at 25hz.

A local telephone company has donated a power supply out of an old hotel switch board.

It has enough power to ring 50 phones at once.... it is a bit heavy.

PS. We are in a country town, the theatre doesn't have a telephone & mobiles don't work reliably inside the theatre.

Catchya, Cliff
