Hello Everyone This is my first post and also my first project with the arduino. I did a workshop so I understand the basics of the platform, but I am new to this, so if you can help me clarify my thoughts or the feasibility of this it would be great! I'm doing a theater play, and I wish to make …

you might be able to find the coil that rings the bell and rewind it with less turns of wire to be able to control it with lower voltage. then you could control it just like any other low voltage solenoid, just pulse it with whatever voltage you wind the coil for.

Thanks! I will check both ways.

I don't know if the ringer would ring at 50hz with same pulse as with the 20Hz, I got a sample that I was studying and the ringing is in sync with an sinusoid LFO/VCO at 20Hz... But I will be disassembling one of the phones tomorrow and test it with that option as well. :slight_smile: (hopefully wo…

You can make one of these with a simple step up transformer and H bridge. If you get a 220V to 24V small mains transformer and drive the secondary of this like it was a motor with 5V and a H bridge at 20Hz then you will get enough out to ring your phone. I made many of these in the 70s also as sta…

hummm this might work.. with an audio amplifier, outputing a 20Hz sample of a sinusoidal wave sent by Ableton Live, through the the free outputs of my sound card. http://wandel.ca/homepage/phonering.html [image] But I have to try to make a simpler version for 3 phones, so I can make them ring n…

with an audio amplifier, outputing a 20Hz sample of a sinusoidal wave sent by Ableton Live, I have seen overkill before but not on this scale!!! This is a thing I did in the 70s with NO computers and two transistors. Don't get hung up on the sin wave shape it is not important, just the frequenc…

I will try to use the arduino to do this. I have (want) to control the 3 phones. So the amp solution is not in anyway practical. I know I can have the arduino control at least 3 relays. I do want it to be safe for the actor that is going to pick up the phones. If I reduce the voltage with the resi…

You can also search the web for a "ring generator." You can either find schematics or buy a unit off ebay or similar.

Very interesting If can offer some advice based on our telephone system in NZ (and Britain). The frequency just makes the ringing sound more urgent. (Ours was 32Hz from memory) The ringer is a pair of solenoids, ie mechanical, so it has limits. It takes about 80-90v AC, but if you look, the bell …

You may want to search google on the subject as making a stage prop telephone ring is a fairly frequently asked question.
