dome-hardware

Bits of pcb and 3D model for the dome controllers, strips, and dome covering.

• PCB: Power and network goes in, WS2812 protocol comes out.
• Shims: go on PCB to stop things touching.
• Toothpicks: go in ends of WS2812 strips and cable tie the cables to them to reduce strain on the strip ends.
• Sheets: Patterns to cut (5 of) to make your dome into a covered dome. These are the raw patterns with none of the seams drawn. Good luck.

Jankyness

Yes, very. Some parts (such as pin bodges in the schematics) are very dirty hacks, even you can even call them that.

Do I need the softwarey things to open the stuff?

• Yes.
• FreeCAD
• KiCAD

How to make things

• PCBs: We used:
  • jlcpcb for the PCBs, they were cheap and fast and it worked.
  • Ebay for the parts. they were also cheap and fast and they worked.
• 3D printed bits:
  • We used a Prusa i3MK3s for the 3D printed parts. It was expensive and slow and it worked. Really. printing 500 toothpicks took days.
  • Conveniently someone had Covid at the time so didn't go outside and could ensure the house didn't burn down. Thanks :)
• For the covering, we used:
  • Sharpies
  • 3.8Oz/sqM waterproof ripstop nylon. (unknown amount maybe 30-40 meters of 1.5 wide?)
  • A giant compass...
  • plastic tent grommet/eyelets
  • 0.38mm thread (too thick!)
  • London hackspace's sewing machine.
  • ...later superseeded by stick with rusty nail and holes drilled at size of sharpie and length in drawing
  • A straight edge
  • Some LX tape (1 roll does it), and a LOT of time.
  • After measuring the first set out, we stuck it to the floor and the ripstop was thin enough it worked like tracing paper to draw the points...
  • This is probably the worst way of doing it.
  • A LOT OF TIME. REALLY. A LOT. WEEKS. (would have helped if we knew how to sew to start with!)

"I have a better way of..."

Nice. if it's elegant of slightly better, do a PR or something...
