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 http://www. thingiverse.comv/thing:49627 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. A complete parts list along is provided at the end of this document. Stargate Inspired Arduino NeoPixel Clock

The clock utilizes an Arduino Uno R3 controller. The Arduino Uno R3 is programmed to monitor and control the (3) time set pushbuttons, chime on/off pushbutton, (4) NeoPixel % 60 rings and the chime speaker. Arduino Uno 7 VDC - 12 VDC Figure 2.11 — Arduino Uno R3 Stargate Inspired Arduino NeoPixel Clock

Lused a Screwshield for the Arduino controller. The Screwshield was purchased from Amazon.com http://www.amazon.com/gp/product/BOOHBVVKPA ?pse=1 &redirect=true&ref =oh aui_detailpage 009 s00 from the vendor jTead and provides screw connections for the Arduino pins. This is handy while developing and provides a rugged connection for /O pins. The Proto Screwshield is shown below.

NeoPixel 1/4 60 Ring The clock utilizes four of the % rings to make a complete 6.2 inch LED clock face that contains 60 smart LEDs. The ring sections are connected as a chain and use only one pin from the Arduino Uno R3 microcontroller. The NeoPixel ring sections can be purchased at Adafruit.com http://www.adafruit.com/products/1768 . The pictures below show the front and back side of the (4) assembled ring sections. Figure 2.31 — NeoPixel Front Figure 2.32 — NeoPixel Rear Stargate Inspired Arduino NeoPixel Clock

The NeoPixel ring sections are soldered together as shown below. I cut a small piece of wire and used this as a solder bridge between sections. I taped the rings down so they would not move while soldering. Figure 2.33 — NeoPixel Solder Connections Stargate Inspired Arduino NeoPixel Clock

DS1307 Real Time Clock The clock utilizes a real time clock module that will keep track of the time even when power is removed. The DS1307 real time clock module contains a coin cell battery that will keep the time for five years. The DS$1307 Real Time Clock can be purchased at Adafruit.com http://www.adafruit.com/products/264 . The D$1307 comes as a simple kit that requires a few solder connections. The only connections to the DS1307 module that are required is 5 VDC power and the SDA and SCL pins. The SDA and SCL connections are interfaced to the Arduino pins Ad and AS. This is a simple an inexpensive solution for creating a clock. I mounted the clock module to the Screwshield as shown below. Note: I also created the same clock with a ChronoDot purchased from Adafruit.com. The ChronoDot requires no assembly and is a more accurate clock module. There are no code changes required if you use the ChronoDot. DS1307 Module Figure 2.41 — DS1307 Real Time Clock Stargate Inspired Arduino NeoPixel Clock

Chime Speaker The clock utilizes a speaker to annunciate the hour and half hour using the Arduino tone command. On the hour the tone played is an eight note Westminster chime. On the half hour the last four notes of the Westminster chime is played. The chime can be turned on and off via the chime pushbutton located on the rear of the clock. The chime speaker was purchased from Amazon.com http://www.amazon.com/gp/product/BOOJMIXYAG?psc=1 &redirect=true&ref =oh aui_detailpage_006_s00 as shown below. Figure 2.51 — Chime Speaker Stargate Inspired Arduino NeoPixel Clock

Pushbuttons The clock utilizes (4) momentary SPST pushbuttons that control the time setting and the chime on/off control. The pushbuttons were purchased at Radio Shack (275- 1547) and are shown below. Figure 2.61 — Pushbutton Package Figure 2.62 — Pushbutton The pushbuttons operate as follows: Stargate Inspired Arduino NeoPixel Clock

The pushbuttons operate as follows: C— Chime Pushbutton. Pressing the pushbutton will allow the chime to be turned on and off. Pressing the pushbutton will toggle between the on and off setting. When the chime pushbutton is pressed and the chime was last set to off, a short up tone will annunciate. When the chime pushbutton is pressed and the chime was last set to on, a short down tone will annunciate. S— Set Time Pushbutton. Pressing and holding the set time pushbutton will put the clock into the set time mode. When the set time pushbutton is pressed and held, the hour or minute pushbuttons can be pressed to increment the hour or minute. H- Hour Set Pushbutton. Pressing and holding the set time pushbutton will put the clock into the set time mode. When the set time pushbutton is pressed and held, the hour pushbutton can be pressed to increment the hour. You will notice the Hour LED (Red) cycle around the clock dial. When you have the desired hour illuminated. Release the Set Time and Hour pushbuttons. M-— Minute Set Pushbutton. Pressing and holding the set time pushbutton will put the clock into the set time mode. When the set time pushbutton is pressed and held, the minute pushbutton can be pressed to increment the minute. You will notice the minute LED (Green) cycle around the clock dial. When you have the desired minute illuminated. Release the Set Time and Minute pushbuttons. Stargate Inspired Arduino NeoPixel Clock

Cabochon The clock utilizes a cabochon for the center of the DHD dial. The cabochon is backlit via a color changing LED that is illuminated for one minute when the clock is at the hour, 15 minute, half hour or 45 minute position. Figure 2.81 — Acrylic Cabochon The cabochon can be purchased at Tapplastics.com. The clock requires one 1.5 “acrylic cabochon. http://www.tapplastics.com/product/plastics/plastic_rods_tubes_shapes/acrylic_caboc hons/139 Stargate Inspired Arduino NeoPixel Clock

Cabochon LED The cabochon is illuminate using a slow changing RGB LED. The LED will cycle between colors by just applying 5 VDC through a 200 ohm resistor on it. The LED was purchased from Amazon.com http://www.amazon.com/gp/product/BO07RO9X82?psc=1&redirect=true&ref_=oh_a ui_detailpage 008 s00.

dhd_cabochon lens.stl This file is an optional lens that you can print with clear filament that is placed between the cabochon and the LED. This is an optional diffuser that will prevent you from seeing the LED though the cabochon. Figure 3.6 - DHD Cabochon Lens Stargate Inspired Arduino NeoPixel Clock

dhd_ bottom cover.stl This file is the cover for the bottom of the DHD base. The cover also keeps the Arduino from falling out the bottom of the base. Figure 3.5 - DHD Bottom Base Cover Stargate Inspired Arduino NeoPixel Clock

Paint The clock was painted with RUST-OLEUM textured paint (Autumn Brown). The cabochon and the power jack were taped off prior to painting. The outline for the symbols were painted using a Sharpie paint pen. u eanenn coat) Figure 4.1 - RUSTOLEUM Paint Stargate Inspired Arduino NeoPixel Clock

Glue the four dial rings The four dial rings as shown in figure 3.4 need to be glued up ina circle as shown. Using sandpaper, lightly sand the edges of the rings where they glue to each other on a flat surface. I use the glue I purchased from Tapplastics.com shown below. The water thin glue is dispensed with a syringe. Try gluing some test pieces together to get a feel for the cure time and properties of the glue. It melts the 3D printed material to fuse the pieces together. Once the pieces are glued together and the dial attached, we will use glazing putty and sandpaper to make any seams invisible. Figure 5.11 — DHD Dial Rings Figure 5.12 - DHD Dial Rings Stargate Inspired Arduino NeoPixel Clock

Glue the dial to the four dial rings Once the four dual rings are glued together to form a circle, the dial is attached to center of the circular ring via the glue from Tapplastic.com. Just be sure to center the dial on the dial rings. Figure 5.21 — Dial/Ring Assembly Pieces Stargate Inspired Arduino NeoPixel Clock

Prepare the parts for painting Sand the base and remove excess filament that may appear below the pushbutton lettering. Using Bondo glazing putty, fill the seams of the glues ring and any areas that require filling/blending. Once the glazing dries (1 -2 hours), sand using 220 grit sandpaper. Repeat as required. Figure 5.31 — Bondo Glazing Putty Stargate Inspired Arduino NeoPixel Clock

Paint the DHD Base and Dial I spray the RUSTOLEUM Autumn Brown on all of the 3D printed components except the clear lens and underside of the dial assembly. Wait for two days to allow the parts to dry fully. They parts feel dry to the touch in a few hours but it is best not to rush the process. Figure 5.41 — Base & Dial Paint Stargate Inspired Arduino NeoPixel Clock

Mount the cabochon and diffuser to the dial Once the paint has filly dried for the Dial / Dial Ring assembly, you can attached the cabochon. Place the cabochon in the center as shown and place a few drops of the glue around the edges of the cabochon. The cabochon diffuser is just a 3D printed white 2 mm thick circle that is placed on the back of the cabochon. The diffuser ensures the LED cannot be easily seen. I just inserted the diffuser against the cabochon and placed a few drops of the glue I purchased at Tapplastics.com on the side of the diffuser so it adhered to the inside wall of the center of the DHD dial hole. Cabochon Figure 5.51 —Cabochon & Diffuser Installation Stargate Inspired Arduino NeoPixel Clock

Glue LED holder to the dial ring The circular LED holder (circle with 5 mm hole for LED) can be glued to the back of the dial ring. The holder should be aligned so the 5 mm LED hole is in the center of the cabochon hole. ~~ LED Holder Figure 5.51 — LED Holder Installation Stargate Inspired Arduino NeoPixel Clock

Wire the LED The color changing RGB LED will need to be wired so that black wire is soldered to the LED short lead and a 220 ohm resistor is soldered to the long lead. The other end of the resistor should have a red wire soldered to it as shown below. a Long Lead Figure 5.71 — LED Wiring Stargate Inspired Arduino NeoPixel Clock

Paint the dial back Paint the back if the dial/ring assembly. The dial was placed on a cup with the cabochon facing the inside of the cup. This prevents getting paint on the cabochon. Figure 5.81 — Back Dial Painting (A) Place a piece of tape over the LED hole so as not to get paint inside the cabochon opening. The painted dial is shown below with the tape starting to be removed. Figure 5.82 — Back Dial Painting (B) Stargate Inspired Arduino NeoPixel Clock

Install the LED The color changing RGB LED will need to be wired so that black wire dered to the LED short lead and a 220 ohm tor is soldered to the long lead. The other end of the resistor should have a red wire soldered to it as shown below. 91 —LED Installati Stargate Inspired Arduino NeoPixel Clock

Install Pushbuttons Install the four pushbuttons as shown. Figure 5.101 — Pushbutton Installation Stargate Inspired Arduino NeoPixel Clock

Wire the Pushbuttons The clock utilizes four pushbuttons for controlling the time setting and chime ON/Off function. Hour Minute Chime Set Time Increment Increment On/Off Figure 5.111 — Pushbutton Wiring Detail (A) Stargate Inspired Arduino NeoPixel Clock

Wire the Chime The chime should have the existing wire leads lengthened by extending the black and red wires. 7 Chime Speaker Figure 5.121 — Chime Wiring Stargate Inspired Arduino NeoPixel Clock

Install the Chime The chime will press into the hole located above the pushbuttons as shown below. Location Figure 5.131 — Chime Installation Stargate Inspired Arduino NeoPixel Clock

Wire the NeoPixels The clock utilizes four of the % rings to make a complete 6.2 inch LED clock face that contains 60 smart LEDs. The ring sections are connected as a chain and use only one pin from the Arduino Uno R3 microcontroller. The pictures below show the front and back side of the (4) assembled ring sections. Figure 5.141 — NeoPixel Front Figure 5.142 — NeoPixel Rear Stargate Inspired Arduino NeoPixel Clock

Place Tape on NeoPixel Ring Clear mounting tape is used to hold the NeoPixel ring on the DHD dial ring. The tape shown below was used since it is clear and double sided. I used scissors to cut small end pieces of tape and placed them around the back of the NeoPixel ring. I purchased the tape at Home Depot. Cinta de Montale Sransporente Figure 5.151 — Clear Mounting Tape Stargate Inspired Arduino NeoPixel Clock

Run NeoPixel Wire through Dial Ring Run the three NeoPixel wires through the mounting hole on the dial ring. Do not stick the NeoPixel on the dial ring yet. I added a piece of heat shrink on the wires as shown so the actual wiring is not visible and to provide a clean appearance. Figure 5.161 — Route NeoPixel Wiring Stargate Inspired Arduino NeoPixel Clock

Mount Dial Assembly to Base Using two #4 screws, mount the dial assembly to the base. Be sure the NeoPixel wire is routed through the base wire channel on top of the base. Figure 5.171 — Dial Assembly Attachment Stargate Inspired Arduino NeoPixel Clock

Wire Power Connection The power connection to the clock is via a standard Arduino 2.1 mm positive tip adapter. To keep the look clean, I a DC power jack female power panel connector that the standard Arduino power adapter can plug into. Since the Arduino just rests in the clock in a vertical fashion and space is limited, I also used a DC power right angle extension cable to allow room for plugging in the Arduino power connector. I cut off the female end of the extension and wired this to the panel connector. The Arduino is a positive tip device so the positive on the panel mount connector is the shorter lead on the connector. When you cut the power extension cable, the red wire is the positive tip wire. Figure 2.71 — Panel Mount Power Connector Figure 2.72 — Power Extension Stargate Inspired Arduino NeoPixel Clock

Wire Arduino to Components Wire up the Arduino to the real time clock and all DHD components as shown below. Data In tthe Clock Control \ Pushbuttons Arduino Stargate Inspired Arduino NeoPixel Clock

Program Arduino and Attach Mounting Base Plate / Bumpers Program the Arduino and verify proper operation. Once everything is working properly, you can attach the mounting base plate. The base plate holds the Arduino in the DHD and prevents it from falling out. The bumpers can also be installed to prevent the clock from scratching furniture. Small #4 phillips head machine screws were used to install the base plate. ~ Figure 5.191 — Mounting Base Plate / Bumpers Stargate Inspired Arduino NeoPixel Clock

Example Clock Display The time shown below is 3:30 and 14 seconds. The hour hand (LED) will increment slightly as the minutes increase. This simulates the operation of actual clock hands. Figure 6.1 — Example Time Stargate Inspired Arduino NeoPixel Clock

3D model description

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

http://www.thingiverse.com/thing:49627

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.

A complete parts list along is provided at the end of this document.
