The bells are different pitch from each other, your slo-mo revealed that mystery! I'm still trying to wrap my head around an easy bi-pass to just make it ring i'll get there it looks a little involved i must learn
Really nice, I did not know that this was possible with the Arduino but when it is, for those who does not have the 3d printer the power could be sent to the secondary windings of a transformer if you have a transformer with 2 approx equal secondary windings. with a common center point, and pulsing on the other ends you will generate 20Hz AC in an OK way. The primary side of the transformer may give more than needed voltage, but 50-110V will be OK for the original ringer so it is not sensitive to voltage. (Because it is so short time of load, and originally a capacitor limits the current. Do not touch the higher voltage! That is the way they did it 100 yrs ago, but with a buzzer and not Arduino that may be more accurate. :-)
Exactly what I'm looking for after a friend bought one of these old phones and want to use as a door bell. So the only addition would be to have a remote switch at the door active the Arduino to then ring the bells. However do you have the schematic of the circuit to build this? Also there was a other comment to use one coil and a flip-flop circuit. Is that the same as a H-circuit?
Interesting videos! Have you considered trying to make it into a bluetooth "headset". Automatically connect to your mobile phone when you come home, and if there is a call, it would go through the rotary? Same with outgoing calls, you dial from the rotary, it has your phone connect the call (AT commands?) and you use the old phone for speaking?
So how about a project converting an old phone to a working mobile phone. Arduino with cellphone board or something? Reading the pulses to let a cellphone board dial out etc etc. Would be so very very awsome to have an old phone without any wires connected to actually work whereever I take it. There must be room inside for a fairly large battery is my guess.
Yes, there should be enough room inside. And the ringer could be replaced with a speaker that would take less room and consume less energy. I am certain that there exist Arduino shields that can do SMSes but perhaps there are also some that can handle calling. Maybe I will try it some time in the future.

I'm trying this project and had the motors working, but, do you have the code that you used in Arduino? How do you program the 20 hz difference between them?
Hi. I'm doing an Arduino rotary phone project too (the Playful Technology video). Just to wish you luck as I'm finding it hard and no result yet, learning about Arduino and wiring at the same time! How do you plan to attach the wires from the Arduino to the phone? I crimped jumper wires into loop connectors but there's often no contact between them...
I am working on the same model and was wondering the same, But I can't see why not. Your replacing the guts with new guts so it should work the same. I haven't tried it yet, but since your post is 9 months old, please let me know if you have and how it worked out.
Sorry for the late response. For some reason UA-cam didn't notify me about your comment. I thought it is pointless since you have to have exactly the same phone. Do you have something very similar?
@@IndrekL I have a PTT SSB 51553. Its slightly different in the way that the magnets are on either side of the bell striker. What have you used for the wire onto the end of the magnets?
@@dadsbeerfund Do you have the original coils for the electromagnets? I removed the original coil since it was designed for 60V that came from the phone line. I dismantled a DC motor and used those electromagnets instead since I had 12V power supply. The wiring I did was pretty primitive. Just two mosfets to activate the electromagnets Flyback diodes.
@@IndrekL I have removed the original coils and have the electomagnets from the dc motors. the person you had print the holder for them, are you still in contact with them and do you think they would do me a custom design because my phone is slighty different?

they are interconnected common connects to one lets say left than a capasitor around 0.20 uF than connect capasitors other end to right side common and connect the live to the right side empty lead. So it will make a series connection not parallel. , look inside the phone's upper case there should be a diagram of the whole thing on a paper. I can't take a photo with my phone as it cannot focus :D
I just checked mine black is common and red is live (either can be live and other is common I think) and two grays connects to a capasitor as seen on the video. check your colors they should be similar
@@SweetyVoltyy Thank you very much for your reply. I am going to pull out my unit and have a look. I do see the old capacitor in your video on top of the coil. I would love to see a wiring diagram of how you got the DC motors to work. This such a great project. One learns a lot from it. Thank you.
@@shvideo1 oh it's not my video, I'm a person just like you searching how to use my old phone hahah. there are more videos for directly connecting it to the phone lines btw but I was intended to use just the ringer part for another application (door ring actually lol)
Hi there. Great explanation. Unfortunately, I'm not electrically handy though I'd love to get my analog phone ring again (just for the heck of it..it's a great old yellow phone). Do you know of anyone that would do this work for me (I would obviously pay for the conversion and shipping!)
My friends there is much easier solution! Just connect in circuit two phones together with 2 wires on each side green and red, then brake one side and install 12 or 24v ac power supply, usually these for alarm and securities is perfect. Now when both handsets are down it will be silenced, as soon as one will be lifted another one will start ringing. I have no idea, why after watching 2 videos i didn't find anything easier, then my method. I need make video for this. Dear owner of the channel, if you see my message and decide to do so, mention my channel. Cheers Serge
Hey! I moved a couple of months ago and unfortunately the phone is still packed up inside a box somewhere in the storage unit. But the schematic was actually pretty simple. Something like this: imgur.com/a/beP4CmS
@@IndrekL awesome! thanks for that. In the middle of trying to make it work right now but I'm using 5v motors. Part of me thinks they may not be powerful enough to do this
Ross Monroe Hi guys, Same here wondering if the coils from 5v motors will be strong enough magnets - or if the bell will sound a bit quiet? Thanks so much for sharing Indrek, so useful!!
Hi, feel free to delete this comment afterwards. Was wondering if I can use a 5-10 second clip of this video? I'm creating a video to explain an ultrasonic motion detector, and I need a telephone bell to discribe very briefly that mechanical bells interfere with ultrasonics. I will of course give a link in the description to your video, and make a card (clickable at top of video) linking to your video. Please let me know if acceptable or not. Thanks, Matt

When I was doing this project I was thinking about using it in an escape room style game. That's why it is purely off-line project.
How? I am searching for this…
Is there a diy written guide for us who need it?
Hi Indrek, nice workarround.
one doubt, the motors have 3 coils, but you are using just one right?
Hey! Yes, I used only one coil.
hey, could it actually work from 2 relay coils, considering boards already have necessary parts for controlling relays (opto, transistor, diode...)
I guess you have to try if these are strong enough.
YEEEEEEEEEEEESSSSS! Thank you.
that's a nice idea and it can be improved to not even needing an arduino I think.

What is your amps for the 12v making the phone ring? Trying to figure out my power supply.
I don't remember exactly, but I think the motor I disassembled, took about 0.5 to 1A if you hold it with force. So it should be the same.
@@IndrekL thanks so much! I’m going to try using a h-bridge to make 60hz at 12v and see if that makes it ring!

Do you have a tutorial on how to build it?
It's hard to make a step-by-step tutorial for this since you wouldn't have exatctly the same phone.
is it possible to get the schematic for the board with the mosfets?
or at least a photo of the board?
Hey! I moved a couple of months ago and unfortunately the phone is still packed up inside a box somewhere in the storage unit. But the schematic was actually pretty simple. Something like this: imgur.com/a/beP4CmS
L1 and L2 are coils that move the hammer. The numbers 1 and 2 are Arduino pins and ground should be connected to Arduino GND

It's interesting bro
Does these types of dial phones contains red mercury.
Red mercury does not exist. It is a scam in India that's been going on for decades. Mercury does not heal you it kills you.
Can you please make a tutorial for a newbie like me... please
For the ringer. How to make the arduinio circuit & the mosphets. From thhe very beginning. I have zero knowledge.
The bells on the ringer need to be tuned
You are probably right. The bells were designed for 60V alternating current that came from the phone line.
lol
Interesting. You could have done it with one coil and a flip-flop circuit.
Hey thanks, this is a great suggestion
