Build a kit that shows time in a traditional manner, in an untraditional way. Use shadows cast from 180 LEDs to create ephemeral analog clock hands.
Humanity has used shadows to tell time from early on:
With the Solarbotics Shadow clock, we're still using shadows to tell time, but with a modern twist. We're using 180 LEDs arranged in three rings to cast a shadow on a clock face, creating the clock hands we are all used to using to tell time. A WiFi-enabled ESP8266 microcontroller offers a convenient way to connect to your Shadow clock to configure it for your own purposes, and being fully open-source, you're able to customize it any way you wish.
For this kit, we developed a solder-free assembly technique so soldering is totally optional. Assembly is either plug-in, or our new bent-leg technique.
Configuring your clock is a matter of turning it on, finding its WiFi access point, logging in, and setting the options. Manually set your time configuration, or configure it to talk to your local WiFi network and use a NTP time-server to keep it super-accurate. Adjust what time you want it to dim at night. Change the way the clock hands "walk" across the face. Pick and set hourly & quarter-hourly time animations. Want to do more? Modify the source-code and upload your own firmware - the design is open-source.
The Shadow Clock is inspired by the BulbDial, another open-source collaborative effort between the Evil Mad Scientists Lab & David Friedman.
