ESP Clock

Touchscreen clock and light controller with WiFi

This was a week-long hack, to build a simple touchscreen clock, with the following features:

• Graphical UI with touch (no buttons)
• Clock synchronization over NTP
• Ability to control WiFi-connected LED lamps
• Web-based configuration UI

This project was partly inspired by the Chumby (remember that?) and by our old X10 light controller (remember those!?). Current iteration's cost is probably comparable to a used Chumby (which also has a lot more features), but it's more fun this way. :) However, the cost could be taken down to ~$10.

Dependencies

• My rewrite of the Digole library
• ArduinoJson
• Time
• Arduino ESP built-in libraries (WiFi, WebServer)

Also, for flashing fonts, you will need the original DigoleSerial library (haven't tested/ported the font upload stuff in my rewrite) and, if you want to substitute your own fonts, the font conversion tools from u8glib/ucglib.

BOM

• Sparkfun Thing
• Digole 2.4" IPS display (in UART mode, with wire soldered to reset pad)
• 500mAh LiPo (optional, but recommended)
• Depending how fancy you want to get with print finishing: XTC-3D resin and/or Bondo putty, spray paint and primer

More details can be found in the making-of post.
