Assembly

Step 1

IMG_5450 Remove the printed supports and adhesion materials from the part.

Step 2

IMG_5456 Use a soldering iron to insert the 4 terminal heatset inserts.

IMG_5462 Insert the M3 terminal bolts and washers into the inserts.

Step 3

IMG_5464 IMG_5467 Strip a length of solid core ethernet cable.

IMG_5471 Separate the individual strands, and remove the twists as much as possible.

Step 4

IMG_5472 Route the wires through the wire channel as shown.

Step 5

IMG_5474 Cut a 250mm length of LED strip.

IMG_5476 IMG_5477 Adhere this around the edge of the light.

Step 6

IMG_5483 Carefully solder the 4 wires to the 5V, GND, D+ and D- pins. This is very fiddly, and may require multiple attempts.

Step 7

IMG_5487 Route the wires out the wire hole, and spread them to each of their terminals.

IMG_5489 Loop each wire around a bolt and tighten, ensuring there is no insulation clamped under the screw.

Step 8

IMG_5492 Use a multimeter to check check for short circuts in the assembly.

Step 9

IMG_5493 Cut out a triangular section of foil to act as the reflector.

IMG_5494 IMG_5495 Use a thin double sided tape to adhere the foil over the back panel.

[!WARNING] Ensure the foil does not make contact with the LED strip or exposed wire. This could lead to a short circut!

Step 10

Repeat for all other desired modules. Attach the lasercut or 3D printed diffuser and bezel.

Questions

How big is the ESPSK6812Driver PCB?

It measures 64.8 × 58.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ESPSK6812Driver use?

12 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the ESPSK6812Driver KiCad files?

From the LordBBQ/LumiLeaf repository on GitHub, at the commit this page was made from: the board is PCB/ESPSK6812Driver/ESPSK6812Driver.kicad_pcb and its schematic PCB/ESPSK6812Driver/ESPSK6812Driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the ESPSK6812Driver design in my own project?

Its repository states no licence, so its author keeps all rights: ask LordBBQ before reusing the design.
