Just acquired a rotary phone but found the internals totally different. The hook switch, for example, has seven wires (ormally open pair, normally closed pair, and a SPDT set of three) and the ringer coil uses four. Working through making good use of the details from the video. Everyone needs a good challenge once in a while. One addition I hope to add is for a scenario with a message like "Don't talk. They are listening. Tap twice if you understand." and turn the receiver into a variation of a knock puzzle. I mean, it's there, and shouldn't be difficult to merge into code on a Nano. Thanks much for the inspiration.

One thing I've discovered after making a couple of phone-based videos now is that there is a huge variety in telephone hardware used across the world (and in handsets from different eras!). So any guide that describes a certain number of wires, of a certain colour, is very unlikely to be universally-applicable! Anyway, glad you managed to do the investigation and got it working for you - great job :)

If people do want to use the microphone they need to be aware that it's a carbon granule microphone that changes resistance rather than a standard microphone that generates a small voltage, reason being that tiny voltage would never survive transmission over long distances without amplification and a balanced transmission system whereas a variable resistance microphone basically uses current loop technology so you'd need to make the mic part of a potential divider.

Thanks so much for the line by line details of the code. Your voice reminds me of "The Secret Life of Machines". Well done. I like how you contain the name of the sketch in the sketch. I had been typing it in manually but this is so much better. Really helps when you need the name of the source file when you want to edit the program.

Unfortunately I was most interested only in the dialing mechanism and the ring bell, now that I have seen this video I realized I could have built a prop like thet for myself if only I hadn't trown away the rest. If I'll ever find another I'll keep everything. Thanks for sharing!

For true realism you need to include howler tone so if the handset isn't replaced properly then after a while a loud tone is played that can be heard even if you're just close to the phone to alert your attention to it.

Can you please make a video about that or give a short explanaition. I have also a second question: what kind of power supply do you use or recommend for powering an Arduino, LED stripes, 12 V locks and these things? I would be glad, if you can help me with these two questions. Thx and go on with your videos.

I love this... phone hacks are cool enough, but when it's a GPO 700 series too? ... sigh! In mine, I just built my ATTiny board into the shape of the circuit board already in the GPO-746 and connected to the solenoids and dial from there. But I ended up needing to put a new microswitch for the "hook" because the existing one was on the GPO board. And I powered the bells from ATTiny controlled DC with an individual connection to each solenoid... which meant 20V DC not 40V AC.

Hello, thank you for your page! I'm just starting out and am excited to get through some projects. However I'm not getting the difference in resistance over T5 and the T19, for the hook switch - it stays on value 1 do you reckon this is a faulty switch ? I have the same model as shown. I do get a change in resistance on T2. 13:37

Hi Alister, I subscribed on the Patrion and set up the phone like yours. The only problem I'm having is the ringer was burned out on my phone so I'm using a motor to spin a small weight to ring a bell. I don't understand how to change your loop codes to just activate a relay on 3 seconds off 2 then repeat untill picked up. Any advice?

Do I understand it right, that you will not include the arduino stuff inside of the telephone? So if it is external, do you re-use the old 4 pole telephone cable? So there will be 7 pins from the telephone to the cirquit: hookPin, dialPin, numberPin, 2 ringingPins, speakerPin and Ground. So 4 pole cable isn't possible, is it? I understood at the beginning of the video, that it will not be nessesary to open the original telephone housing?!

Hi Randolph, yes I've done that in several projects on this channel - using an Arduino, a Raspberry Pi, or a Teensy. It's just detecting input (via a rotary dial, as on this project), and triggering appropriate output (I.e. playing sound file from SD card, via speakers)

@PlayfulTechnology2 жыл бұрын
Hi! It's funny - I've actually had several people ask if I could do a tutorial on making an "audio guestbook", and I have to confess I'd never even heard of them before! So, can you explain how you'd expect it to operate in a bit more detail? Do you have to press any buttons or dial any number at all? Or do you just lift the handset and speak ("after the tone"?) and it records everything until you hang up?
@mayrar89092 жыл бұрын
@@PlayfulTechnology Wow! First of all, thank you so much for taking the time to read my comment and write back! The audio guestbook is a new fad that started probably a few years ago. To answer your question, based on some of my research it looks like you can either have the guest dial 0 and they'll hear the greeting first then after the tone it records. Or a common one is as soon as you pick up the phone you'll hear the greeting and then recording starts after the tone. Each recording ends as soon as you hang up. So it can be simple as just picking up the phone or dialing 0.

Public telephone networks differ from country to country, from the voltage on the line when the phone is on-hook, the frequency of the AC ringer signal, and the way pulses and voice data is encoded. BUT, for this project I'm just using the basic components found in the telephone- the microphone, speaker, mechanical dial mechanism etc., and they work the same wherever.
