3D Printing Brackets

- Print 1 top and 1 bottom bracket. 60% infill and a raft are recommended.

- Using a soldering iron, insert the heat-set thread inserts. Eight in

bottom plate, 4 in riser posts, 4 in Arduino mounts. Two in top plate for

magnetometer mounts. See the demo video below (not mine, borrowed)

Top Plate Assembly

- Attach the magnetometer with 4-40 nylon screws. Shear the excess length flush

with the bottom of the plate using a hobby knife. Be careful to not break

the superstructure on the printed part.

- Place the capacitor into the cut-out and secure with a drop of hot glue.

- Solder ~5 cm of wire onto the data in line on the 16-element ring.

- Place the 16-element NeoPixel ring into the vertical ring holder. Thread the

data-in line through the hole in the bracket. This ensures that data-in, V+,

and GND are all accessable. Secure with a drop of hot-glue.

- Place the 24-element NeoPixel ring onto the riser posts. Line up the data-out

pad to be near the data-in line on the smaller ring. The LED should be directly

above the mounting post. Secure with hot-glue on each post.

Bottom Plate Assembly

- Secure the Arduino RedBoard to the base plate with 4-40 nylon screws. Shear

the excess length flush with the bottom of the plate using a hobby knife.

Attaching the plates

- Using the 4-40 nylon screws, attach the top and bottom plates. Shear

the excess length flush with the bottom of the plate using a hobby knife. You

may prefer to do the wiring with the screws out for easy access, but it

shouldn't be too much of a problem.

Wiring

- Trim and solder the data-in wire on the vertical ring to the data-out pad

on the 24-element ring.

- Connect the data-in pad on the 24-element horizontal ring to pin 13 on the

Arduino. The resistor goes in-line here as well. You can use 0.1" header to make this easier to assemble and troubleshoot.

- Connect a ground pad from the 24-element horizontal ring to a ground pad

on the 16-element vertical ring.

- Connect the second ground pad on the 16-element vertical ring to the ground

size of the capacitor (marked with -- on the case).

- Connect the ground side of the capacitor to GND on the Arduino. Header can

make this easier.

- Connect the power pads of both rings to the positive side of the capacitor.

- Connect the positive side of the capacitor to +5VDC on the Arduino.

- Connect the GND, SDA, and SCL pins of the magnetometer to GND, SDA, and SCL

on the Arduino.

- Connect the power pin of the magnetometer to the +3.3VDC pin on the Arduino.

Programming

See the linked GitHub repository for the code and more resources!

- Install the [NeoPixel](https://github.com/adafruit/Adafruit_NeoPixel),

[Adafruit Sensor](https://github.com/adafruit/Adafruit_Sensor), and

[Magnetometer](https://github.com/adafruit/Adafruit_HMC5883_Unified) libraries.

For help, see the [library tutorial.](https://learn.adafruit.com/adafruit-all-about-arduino-libraries-install-use)

- Connect the Arduino to your computer and upload the code in the Arduino/Vector_Display directory (see the [Arduino guide](http://arduino.cc/en/Guide/HomePage)) if you need help uploading programs to the Arduino.

- Play with parameters such as brightness and grading to create your own display!
