The “do not be alarmed” clock #ESP8266 @Stavros

Stavros Korokithakis has long thought that a bedside alarm clock would be perfect, but he couldn’t find one that fulfilled all his requirements:

  • I needed something that had a screen that would always be always lit, so I could check the time with one eye and half a brain awake, in the complete darkness of the bedroom.
  • A screen that wasn’t too bright and wouldn’t disturb sleep, but that would also be legible in direct sunlight, so I could see the time during the day. This meant adaptive brightness.
  • Octagonal shape so I can lay it down on its side (or at 45°) instead of having to crane my neck up to check the time when lying down (I really did think of everything).
  • Weather forecast for the next hour or two, so I can reliably fail to wake up for tennis when not necessary.
  • Annoying beeper for alarms.
  • Less annoying built-in LEDs that would increase in brightness for a few minutes before an alarm went off, so I can wake up less annoyed.

Conceptually, making an alarm clock to fulfill these requirements isn’t hard. You take a small OLED screen, an ESP8266, connect them together, add some LEDs and a buzzer, and you’re done!

The result is a nice bedside clock with OLED display and 3D printed case.

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
