How does a rotary phone work?
The rotary phone used to release the line for a fraction of seconds 1 to 10 times to dial a digit. The whole system was working without any silicon, with only relays and electromechanical components.
How do I charge my rotary phone?
With the rotary phone’s housing open, put the battery in place and turn the switch ON. If nothing is happening, plug the charger cable into the phone and connect it to a USB power supply (5V 0.5A).
Can you buy a rotary cell phone?
And you can buy it, too. The rotary cell phone is the work of Justine Haupt, an engineer at Brookhaven National Laboratory in New York. Haupt documented the development of the device on her website, describing it as a “quick and dirty project.”
How do you make a rotary phone without a phone line?
The goal is to keep the phone as it used to be, with its electromechanical bell ring, and of course the rotary dial, but this time without the line wire. To achieve that, the simplest thing I’ve found was to build an interface between the rotary phone hardware and a cordless analog phone handset.
How do I connect my rotary phone to my cell phone?

Can you call a cell phone from a rotary phone?

Can I use my mobile as a landline?
Voice Bridge essentially turns your smartphone into a second interface for your landline and allows it to act more like your cell number. It goes the other way, too; users can make landline calls from their smartphone, but those calls will use up data unless you're on Wi-Fi.
Does pulse dialing still work?
The answer, said Violette of the Telephone Museum, is almost certainly no. For one thing, nobody actually makes them anymore. You can find old ones online if you hunt, and there are new phones that have a dial – but they're fakes. They don't actually use pulse dialing; they translate the dial's spin into tones.
Will a rotary phone work with Verizon?
"And I can report, for anyone curious, that rotary dialing works perfectly well on FiOS digital phone lines."
Do you need a landline for a rotary phone?
Re: Make old phones work without landline You can dial from one phone to another by dialing a 2-digit extension number. It works with both rotary and Touch-Tone phones. These are usually around $50-$100. Additionally, you can still use corded phones with your cell service by getting a device such as the X-link BTTN.
Is there a Bluetooth rotary phone?
The SparkFun original Portable Rotary Phone has been upgraded! With the Blue Rotary we've taken everything people love about the Port-o-Rotary and substituted the cellular module for a Bluetooth® **module. So what's different? You no longer need an activated SIM card to use the phone.
Are rotary phones analog?
Ironically, rotary dial (or pulse-dial) is actually digital protocol, and is supposed to be closer relative to VoIP than "modern" push-buttons phones. The later ones use analog encoding to transmit digits. This process has a fancy name: Dual-Tone Multi-Frequency Signaling (DTMF).
How can I use my Android phone as a landline?

Who invented the rotary phone?
The rotary cell phone is the work of Justine Haupt , an engineer at Brookhaven National Laboratory in New York. Haupt documented the development of the device on her website, describing it as a “quick and dirty project.”.
Does Haupt have a dialer?
Haupt’s rotary cell phone features … well, not very much. But for some that will be its appeal. Some of the physical buttons on the device, for example, can be set up to link to frequently called numbers, eliminating the need for a touchscreen and menu. Just to be clear, the dialer does work, and can be used for other numbers that you don’t save.
How Landlines Work
The primary way to use a rotary phone is with a landline. There are alternatives that will be discussed later, but let’s start with the basics.
Challenges in a Digital World
So, if you can plug a rotary phone into a landline (that is working), the rotary phone can place and receive calls. You don’t have to do anything special to make it work. The POTS system is still in place around the world and still works just fine.
Using a Rotary Phone With Your Cell Phone
If you don’t have a landline at all (which is now true for the majority of Americans), you can actually still use your rotary phone. It gets a little weird, but there are digital interfaces that allow you to use the rotary phone in conjunction with your smartphone.
The XLink Bluetooth Gateway
To better explain this idea, we can look at a specific attachment that connects a rotary phone to a smartphone. In this case, we’re looking at the XLink Bluetooth Gateway. XLink makes a few products in this category with mostly similar functions.

Step 1: Just a Bit of Theory
The rotary phone used to release the line for a fraction of seconds 1 to 10 times to dial a digit. The whole system was working without any silicon, with only relays and electromechanical components.
Step 2: Technologic Choices
I choose to use DECT analog cordless phones for this project as they are really common and not expensive. This project should also work with an old analog cordless phone as well.
Step 3: Circuit Design
The circuit is basically an interface between a cordless handset and the rotary phone’s hardware. The functions it carries out are:
Step 4: Software
Beside dialing using Roman Black’s DTMF algorithm (tut13), the software is in charge of power management shutdown, hang-up detection, dial reading, ring detection,…
Step 5: PCB Design
PCB is two layers. I draw it using DIP Trace. Feel free to use the Gerber files to make your own. I did it with through-hole component for easier DIY soldering, except for 2 chips that don’t exist in DIP package. But with flux, small tip and patience, it is possible to solder it with an iron.
Step 9: How to Choose the Cordless Phone
The design is done to be as universal as possible and should work with the majority of DECT cordless phone as long as they have the following specifications:
Step 18: Putting It All Together
When all tests and settings are done, power OFF the phone and unplug the cordless handset.
