Fifth Element extending light

First off, this is not easy to build. soldering is complicated in some areas, you will break some things while trying to assemble it. If I would have to redesign it, I would incorporate a power distro board and also I would restrict myself so much in size. This was designed to be printed on a Prusa Mini (18cm height). Everything fits perfectly inside, but there is no room for error.

Print Guide

Outer shell .1 layer height recommended. 

The frame needs a lot of supports, be careful when removing them, I broke a couple doing that.

It's very likely that the limit switches will not properly trip. Just print two of the limit switch tolerance helpers and push them onto the metal part of the limit switch.

Partlist

• Beige filament or similar recommended (filament color should roughly match the color of the textured paint)

• Transparent PETG

• 1x ESP32 (50mm between bores, some newer models differ, mine still has micro usb)

• 1x Servo Feetech FS5103R

• 1x USB-C Port SparkFun BOB-23055

• 2x Limit Switch WK330

• 9x Circular LED PCBs WS2812B 

• 1x Push button TS02-66-55-BK-160-LCR-D or similar

• Power brick 5V, 2A

• 2x M2x5 Brass insert

• 2x M2x6 Hex

• 1x M3x4

• 3x M3x6

• 4x M2x6

• 4x M4x6

Other than that you need wires and paint for the finish of the print. I would recommend printing in a beige color. I used black and had a hard time with the paint to cover everything evenly.

Electronics

• LEDS

  • DIN -> GPIO 2

• Upper Limit

  • Common -> 5V

  • NC -> GPIO 4

• Lower Limit

  • Common -> 5V

  • NC -> GPIO 18

• Push Button

  • Terminal 1 -> 5V

  • Terminal 2 -> GPIO 15

• Servo

  • Signal -> GPIO 17

Software

The software is fully written by Claude AI. I know how to code, but this was faster. Expect some things not ideally solved in code, but it works without any issues.

The .ino is attached. 

The values below might need adjustment. If the servo does not sit still in either position the first value needs adjustment.  The other two are speed values.

SERVO_STOP = 92 ← Servo stationary

SERVO_UP = 85 ← Moves up (LEDs brighten)

SERVO_DOWN = 99 ← Moves down (LEDs dim)

Once the ESP is on, connect to the "Fifth Element Stone" WIFI. It will prompt you to log in. In this captive portal you can adjust your settings. Keep in mind, they will be gone after power cycling.
