Arduino MIDI Telephone Ringer Revisited

A little while after my last set of experiments for a Arduino MIDI Telephone Ringer I found a video from "Gadget Reboot" showing how to use the KS0835F subscriber line module from an Arduino to interface to a phone more easily. So I bought some and this is the start of a set of new experiments … Continue reading Arduino MIDI Telephone Ringer Revisited →

Arduino MIDI Telephone Ringer – Part 3

The last thing I wanted to do with my (dual) telephone ringer, well, besides trying to find six more phones and get an octave's worth of ringing, was put my dual-ringer into a box. This shows how I managed that. In part 1 I talked about the basic hardware and approach. In part 2 I … Continue reading Arduino MIDI Telephone Ringer – Part 3 →

Arduino MIDI Telephone Ringer – Part 2

Following on from part 1, I've added BT style sockets and upgraded the ringer to ring two phones. Polytelephony if you will. In part 3, I switch to an Arduino Nano and put all the circuitry into a box. https://youtu.be/IBBd9z4hKYw Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Arduino MIDI Telephone Ringer – Part 2 →

Arduino MIDI Telephone Ringer

One thing I love about those vintage rotary telephones is the characteristic ring. But making them do that outside of being plugged into the PSTN isn't easy. But I wanted to see if I could make it work over MIDI, so this is my approach. In part 2 I add some BT style sockets and … Continue reading Arduino MIDI Telephone Ringer →

Vintage Rotary Phone MIDI Controller – Part 7

Having built my adaptor into a small box, I've gone back to add a mode button so I can include all the different applications into a single sketch. This builds on the previous parts in this series. Part 1 - Understanding the telephone hardware and interfacing to an Arduino. Part 2 - Decoding the rotary … Continue reading Vintage Rotary Phone MIDI Controller – Part 7 →

Vintage Rotary Phone MIDI Controller – Part 6

In this final (for now) post, I'm just tidying up the circuit and using a Pro Mini to embed all the electronics I need into a nice small box. This builds on the previous parts in this series. Part 1 - Understanding the telephone hardware and interfacing to an Arduino. Part 2 - Decoding the … Continue reading Vintage Rotary Phone MIDI Controller – Part 6 →

Vintage Rotary Phone MIDI Controller – Part 5

In this post, I describe how to use my rotary phone as a simple random-note MIDI "sequencer" of sorts. The triggering of the notes is driven from the pulses of the dial. This builds on the previous parts in this series. Part 1 - Understanding the telephone hardware and interfacing to an Arduino. Part 2 … Continue reading Vintage Rotary Phone MIDI Controller – Part 5 →

Vintage Rotary Phone MIDI Controller – Part 4

In this post, I describe how to use my rotary phone as a MIDI program changer. This builds on the previous parts in this series. Part 1 – Understanding the telephone hardware and interfacing to an Arduino. Part 2 – Decoding the rotary dial from the Arduino. Part 3 – Rotary phone MIDI note controller. Part 4 – Rotary … Continue reading Vintage Rotary Phone MIDI Controller – Part 4 →

Vintage Rotary Phone MIDI Controller – Part 3

This is the first musical application of my vintage rotary phone. I'm using it as a simple MIDI note generator. Remember, I really wanted to keep this as a potentially working phone when not plugged into an Arduino. This builds on the previous parts in this series. Part 1 – Understanding the telephone hardware and interfacing … Continue reading Vintage Rotary Phone MIDI Controller – Part 3 →

Vintage Rotary Phone MIDI Controller – Part 2

This it the second in a series of posts looking at interfacing an Arduino to a vintage rotary telephone for musical purposes. Part 1 – Understanding the telephone hardware and interfacing to an Arduino. Part 2 – Decoding the rotary dial from the Arduino. Part 3 – Rotary phone MIDI note controller. Part 4 – Rotary phone MIDI program … Continue reading Vintage Rotary Phone MIDI Controller – Part 2 →
