My desc lamp with pantograph stand.
Stand based on carbon tubes Do-16mm, Din-14mm. In my case tubes have 390mm length but you can order tubes of length you need. As an alternative tubes could be printed, i think, but idea was to use purchased ones.
This stand does not have springs and relay on friction power, so i printed parts of PLA-CF.
Electronics built around WEMOS D1 ESP-WROOM-32 CH9102F module and esphome built firmware.
Electronics contains:
- usb-c 12v trigger module (installed inside of box on back-bottom tube)
- MH-MINI-360 dcdc step down converter (to power up esp32)
- XL6009E1 DC-DC Step-Up converter to powe up lamp (some usb-c chargers can output only 9v instead of 12 that's why it is a good idea to use such converter here)
- TTP223 touch sensor (ensure your sensor in mode when it can handle long presses and not cutting off signal)
- a single WS2812B 5050 RGB LED module, to indicate lamp status
- 535 mosfet module to control led lamp
- few pieces of 10mm led stripe
