TWO NEW GUIDES: Telephone Edition @adafruit @johnedgarpark #adafruit

Things are looking pretty phone-tastic here at Adafruit Learn Guide central with this pair of retro telephone projects.

First up is the Rotary Phone Dial Keypad. This project shows you how to non-destructively modify a Western Electric 500DM rotary phone and turn it into a USB number entry device! A KB2040 Kee Boar interprets the dial pulses and then sends key-presses to your computer or mobile device.

Second is the self-contained Touch Tone Phone Dial-a-Song built with a Western Electric 2500DM (the successor to the 500DM) and a Feather RP2040 hidden behind the keypad. With it, people can dial a number to hear a song or message played through the handset earpiece. The CircuitPython keypad library makes it simple to read the Touch Tone keypad matrix.

I’m not going to tell you how to live your life. However, should you choose to put some They Might Be Giants songs on there, you’ll be a hero.
