What is it?

Smart phones are great, but you can't beat the charm of a vintage rotary phone with actual metal gongs for the ringer.  The doorbell phone rings any analog phone with the push of the wireless doorbell button. 

Why Do I Need It?

Rotary phones are amazingly beautiful!  The Doorbell Phone makes these amazingly designs useful again.  Here are just a few examples of what you can get on Etsy right now. (used with permission, more info here)

How Does it Work?

You just hook the system up to your phone or the phone we provide for you.

The system consists of:

1.  A wireless doorbell button

2.  A doorbell module

3.  A power adapter

4. (multi-button packages only) a second wireless doorbell button

5. (complete packages only) a vintage style rotary phone

The doorbell button is battery powered, so there is no wiring required at the door.  The doorbell phone module plugs directly into a standard power outlet.  Plug the phone into the standard US phone jack on the module and your phone will ring whenever the doorbell button is pressed.  If you don't have a phone we can provide a brand new vintage style rotary phone as part of our Complete Doorbell Phone Package.

Need a doorbell on more than one door?  Our multi-button packages ring a single phone with two wireless buttons.  One button rings a standard US ring, while the other rings with a standard UK ring.  A simple and fun way to tell which doorbell is ringing.

Design

As with all Robomotive designs, the Doorbell Phone has simplicity of operation as the primary design objective.  The doorbell phone uses a wireless transmitter button, which is the only operator interface.  The button transmits to a receiver in the module.  The receiver signal is sent to an Adafruit Trinket, which sets the ringer and commands the phone ringer circuitry.  Analog phones operate on 35 to 70 volts DC, so bulk of the circuitry is involved in stepping up the 6V input voltage to something the phone can use.  The ringer frequency and duration is determined by the software in the Trinket, so if so inclined the savvy owner could change the ring to suit their preference.  For instance, we've had it ring using a UK standard ring in the past. 

What's done

All development costs have already been funded.  The prototype doorbell phone is currently working as the only doorbell in my house (Trick-or-Treat was fun!).  This unit uses all the same electronic components as the production unit, but on a prototype PCB.  The production PCB design is about 50% complete.  The unit is currently in a prototype enclosure, which is tucked away out of sight in my installation.  The production version will retain this small and easily hidden design.  The video above shows the actual installation in my home.  The Multi-Button versions are a little behind the others, and will be shipping slightly later.

What's left to do

Finish design of the production PCB and have units made. We also need to finish enclosure design, which will be 3d printed plastic until injection molding tooling is made.  All of these items will be complete prior to the end of this campaign.

Funding

Remaining funding requirements for this project are relatively modest, and mostly consist of volume pricing for components. A 3d printer is also planned for the early component cases, most of the cost of which will be funded from other sources.

Gift Giving

Clearly we won't be shipping by Christmas or Chanukah, but you can still give the Doorbell Phone as a gift.  If funding is successful early enough we can send a printed gift card on request.  If we go down to the wire we can send the card digitally.  Here's our draft graphic below:

Risks and challenges

The tasks remaining required to complete the production version of the doorbell phone are well understood and relatively simple. The prototype versions utilizes all of the electrical components of the production version, but has a hand built circuit board and prototype enclosure. In the case of the multi-button versions the microcontroller may change to a smaller version as well. The production printed circuit board (PCB) design is nearly complete, and vendor quotes have been included in cost estimates. The final production enclosure will be injection molded plastic, but early units will be 3d printed. Let us know what you'd like it to look like!

Funding from this campaign is required to order the first batch of PCBs and a 3d printer for the first batch of enclosures. Our pricing depends on a certain volume, and once our funding goal is reached will send volume orders to our suppliers. Our longest lead supplier is 3 weeks, so productions units are expected to be ready shortly after he close of the campaign.
