Intelligent workshop organiser - WS2812B - illuminated drawers with database

p.kaczmarek2 7113 35

TL;DR

  • Built smart workshop drawers with WS2812B LEDs and a database that highlights the drawer cells containing a searched part.
  • Each drawer gets one diode, controlled by BK7231N or ESP8266 through REST requests from a browser, phone, or computer.
  • A 60-drawer segment uses a 1 metre, 60 LEDs per metre WS2812B strip, a NodeMCU, and a 5V 5A power supply.
  • The PHP site lets you add, delete, view, and update parts, while JavaScript triggers the controller to light matching drawers and ambient colours.
  • The final setup works and is responsive, but soldering the LEDs is time-consuming and careful drawer-to-LED indexing is critical.

    10k of what? Because I don't think it's Farads, it would rather not fit in the drawers if it exists at all :)

    It would be nice to have a remote control that says "capacitor10k" for example. - click and the correct drawer lights up:)
    .
    In this case a red light should go on because what is a "10k" unit in relation to a capacitor?

    Clinging to details... After all, I wrote e.g. (for example).... Anyone can write whatever they want, their own password...... The general idea was to make it a bit easier to search....

    This... then you would still have to change the subtitles on the remote control and worse, a remote control with as many buttons as the number of drawers.

    I would rather stick the inscriptions on the drawers than on the remote control because I would still have to find the inscription with my eyes among the dozens of different ones and, as you know, a small remote control means smaller inscriptions...

    On a more serious note, the "Ok Google..." solution is much more functional than your remote control. is much more functional than your remote control because it even creates the "stickers" itself (example with red tape).

    I have bad memories of this soldering, you have to be patient. It's not that it's difficult, because the solder came out the first time, but it was time consuming

    I agree with this opinion. I do not recommend it.

Topic summary

✨ The discussion revolves around a project for creating "smart" workshop drawers integrated with a parts database, allowing users to easily locate components by highlighting the corresponding drawers when a part name is entered. The project utilizes a WS2812B LED strip for illumination and is controlled by a BK7231N or ESP8266 (NodeMCU). Participants express interest in enhancing the system with voice recognition capabilities, suggesting the integration of AI assistants for hands-free operation. Concerns are raised about the potential for drawer misplacement and the need for a reliable mapping system, with suggestions for using QR codes or NFC tags to maintain organization. The practicality of the system is debated, particularly in environments with numerous drawers, where manual organization may suffice. Overall, the project is praised for its innovative approach to inventory management in workshops.
