The Stargate DHD clock will display the time using NeoPixel LED’s oriented around a simulated clock face. The clock provides an hourly and half hour chime that can be turned on and off. The hours and minutes can be set via pushbuttons located on rear of the clock base. The center crystal on the DHD clock will illuminate on the hour and half hour for one minute. The illumination of the crystal is provided via a color changing RGB LED.
The hour is represented by a NeoPixel LED changing to red, the minute is represented by a NeoPixel LED changing to green and the seconds are represented by the NeoPixel LEDs changing to a blue color as the second’s increment. Using this method, reading the clock is very intuitive. As the seconds increase, each LED will change to a blue color. The Red (Hour) or Green (Minute) LEDs will not be overwritten by the Blue seconds LEDs.
The clock is 3D printed and utilizes one Arduino UNO, four NeoPixel rings and a real time clock.
The .stl files for printing the clock parts and the Arduino Uno code are located here and can also be found at www.guarnero.com.
The 3D clock dial and base are based upon the work of Techno35 at
The dhd (dial home device) dial was resized so that it can print on a Lulzbot Mini printer and the dhd (dial home device) base was resized and heavily modified to provide a housing for the electronics.
The .stl files include the dial, base, ring sections for mounting the NeoPixels, crystal LED mount/cover, base cover and the crystal lens. The entire clock was printed with HIPS filament with the exception of the crystal lens which was printed with clear ABS. The clock is painted so any color filament will suffice.
