Cost

The cost of the workshop is 25 euros. This covers the cost of parts which is approximately 18. The extra 7 euros will go the Hackerspace Nijmegen. Either in the form of extra parts (when not all slots are taken) or in the form of a donation (if the total revenue exceeds the cost of all parts).

Details

The clock is build around an ikea ribba photo frame. The letters are formed by a lasercut sheet of black paper. There are two configurations: either the letters are in front of a white screen and light up when activated, or the latters are behind the screen and shine though the all-white front and the letters are invisible when not active. The lights are provided by 96 RGB addressable leds. The leds are controlled by a wifi-enabled esp8266 microcontroller. The microcontroller fetches the local time via ntp and will always be in perfect sync and even automatically adjust for daylight saving time.

The code is easily modified for different styles and effects. The is example code for several add-ons such as dimming at night (in case you place the clock in a bedroom) or showing the weather forecast instead of the time (requires a different letter grid).
