Summary

Huge Seven Segment

Printed parts

7x base.stl
7x top.stl
4x link-2-way.stl
2x link-3-way.stl

Hardware components

7x Neopixel strips (I used 3 pixels long strips per segment)
Wires to connect them all
Arduino or similar to drive it

Assembly instructions

1) Glue (at least I used glue) the Neopixel strips to the inside of each base
2) Thread three wires (power, ground, signal) through the holes in the links (I recommend using different colors for each wire). Mind the wiring of the two "3 way links" - think them through ;) Check the "wiring guide"-picture above.
3) Snap the links in to the holes of the bases to lock everything in to place
4) Cut/strip the wires and solder them to the Neopixel strips
5) Snap the tops on to the bases
6) Connect the "starting-wires" to an Arduino or similar that will drive the Neopixels

Code

I've put together a simple Arduino sketch that shows how to get numbers on to the display. It can serve as a good starting point to get you going. You'll find it over at GitHub.

Notes

This is still a work in progress. What I'd like to address is the wire "entry and exit point" of a 7 segment display.
