This Is the Watch That Makes a Coin Cell Look Awesome #WearableWednesday #wearabletech @hackaday #Arduino
This watch is a beauty from its apple wood frame to its concentric LED circle display, but the focus is really a coin cell battery. LiquidWatch, spotted on Hackaday, is an entry in their #CoinCellChallenge. Designed by CF, the time piece concentrates on an artistic design with a focus on nature inspired materials. The leather band and wood poses as soil with a face that has light dancing on turf.
The PCB uses an ATmega 328P with 97 tiny LEDs, and you can see CF has developed a new square version of the board as well. What makes the watch unique is the different modes, including a single LED or fill-in style display. There’s also a fun way to check battery power and an option for displaying seconds. Check out the watch in action.
CF definitely has a passion for time devices, so be sure to check out his other projects on Hackaday. If you like the idea of a circular LED time device, check out our learning guide for the Neopixel Ring Clock. Our Flora microcontroller combines with two different Neopixel rings to make a beautiful display while a GPS module provides accurate time. Mount it on a band or wear it as a pendant—you’ll have people asking you for the time and a list of parts. Make time for making time.
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.
