LED lamp in the shape of a pencil

Immediately after seeing PELARBOJ, I started thinking and planning. I wanted to create something similar to it. After a few iterations, this is my result.

Bill of materials:

• 1x Adafruit NeoPixel 16 LEDS 44.5mm diameter.
• 1x USB-C port (panelmounted JRC-B008), I got 10pcs at Aliexpress for cheap.
  • There is an alternative version of the base and insert that takes a circular 5.5 mm x 2.1 mm DC jack. Will add that soon as well.
• 1x ESP8266 D1 mini.
• A few short cables, preferably black, red and some other color.

Printing the parts:

• Main body, print in vase mode. Use material that lets light trough.
• all other parts, print like normal.
  • Use brim on all parts except Base and Insert.
  • Use material that lets light trough for the top.
• Use support on the insert.

Assembly:

Read the PDF for instructions with imaged, or read below.

• Solder a red wire to the USB-C terminal labeled “V”.
• Solder a black wire to the USB-C terminal labeled “G”.
• insert the USB-C jack in the base and secure it with two screws (came with the terminal).
• Prepare the ESP8266:
  • Connect the ESP8266 to your PC and navigate to install.wled.me and follow the instructions to install WLED on the board.
  • Solder a red wire to 5V.
  • Solder a black wire to GND.
  • Solder a third wire to D4.
• Insert the ESP8266 in the base.
• Add the insert, have the cables from the ESP8266 coming out in the center.
• Add the NeoPixel ring to the insert.
• Solder the following on the NeoPixelring:
  • Solder both black wires to “power signal ground”.
  • Solder both red wires to “power 5V DC”.
  • Solder the last wire to “data input”.
• Insert power and make sure the installation works.
• If all is ok, add the top to the main body.
  • The fit can be very tight if printed in PLA, but some heat to the parts will help.
• Insert the main body and top in the base.
• Attach the light blocker to the main body, use some glue if preferred.
• Insert the USB-C/power-cable.
• Enjoy!
