This 120mm Stargate rotates the symbol ring and controls the chevron LEDs based on 7-chevron address, which can be programmed by the DHD button. The gate rests on 4x6 Openlock base.
File Stargate.pdf contains design principles and assembly instructions. See also video https://youtu.be/m7Bo0lUhz8U.
Arduino sketch can be found at Thingiverse: https://www.thingiverse.com/thing:4782980. I was not able to load .ino file to MyMiniFactory. Advice accepted :)
DHD button controls the operation, which has three modes:
- Dialing is started by short pressing of DHD button – the gate dials a 7-chevron address saved in EEPROM. The gate stays open for 1 minute and then closes by itself.
- Programming mode is activated by pressing the DHD button for 5 seconds. Then the button is used to control rotation and direction for each of the 7 stages in order to define the address; the address is saved in EEPROM of Arduino.
- Tuning mode is activated by pressing DHD button for 10 seconds. Then the gate rotates very slowly when DHD button is down. This mode is used to align the symbol ring correctly with the middle chevron.
