This project is incomplete. I've hit a major roadblock and haven't had the time to return to it! I do plan on completing this project sometime...

ESP32 Alarm Clock¶

Overview¶

A DIY alarm clock using salvaged 7" LCD displays from old intercom devices, an ESP32, and (maybe) a wireless snooze button.

Hardware¶

ESP32 microcontroller
7" LCD (salvaged from intercom)

Undecided

Encountered severe issues with the intercom OS that would take too long to reverse-engineer. I'm considering moving towards a small projector rather than an LCD...

Radio (or maybe bluetooth?) transmitter/receiver with a big ol' snooze button

Features¶

NTP time sync over WIFI, so the time is always accurate
Accounts for daylight savings time
Huge digits so my blind ahh can see the time when I'm in bed (without glasses)

Build Notes¶

TODO

Add wiring diagrams, code snippets, and images
