Flashing vintage LEDs or how we warn about “fires” on the project

    vintage Polish flasher of 1984 was discovered in the open spaces of Avito. If there's a fire somewhere, then let this thing turn on! The piece was promised even in almost working order. 500 rubles and it's in my backpack. So let's add some IoT hype and Arduino sketches to it.

    The code is posted on github , there is no authorization, sprawling API and beautiful html pages. MVP only, hardcore only! Use at your own risk, I warned.

     

    Solid products

     

    When the software is written, it’s time to start the flashing light. Below is a diagram that should help you understand the device.

     

    Expectation:

     

     

    Reality:

     

     

    So we replace Sonoff SV with:
    Arduino UNO + wiznet w5100 + Relay

     

    Pin connection:
    DIGITAL 10 – SS
    DIGITAL 11 – MOSI
    DIGITAL 12 – MISO
    DIGITAL 13 – SCK
    GND – GND
    5V – 5V

     

    We connect the relay even easier: the signal pin to DIGITAL 4, the power wire to the flasher is hooked into the gap at C (common) and NC (normally closed).

     

    Achtung!
    See the documentation for your devices. It is not a fact that by connecting the Ethernet board to 5 volts, you will not get a funny smoke when testing! In my case, everything is normal, and the module is designed to be powered from 5 volts.

     

    Plastic products

     

    An ad on Avito stated that the flasher was nearly operational. Over the years, only one part has died in it – the gear that rotates the reflector.

     

     

    Exhale, pick up Fusion360, model a new one and print on an office 3D printer.

     

    Gear Modeling Process

     

    We lubricate the gears, replace the wires, put them back together – it works!

     

    It would have been nice to print a nylon gear, but the first fine print failed, and the second sample from the bestfilament was not enough for the second.

     

    That for which we are – in spite of everything!

     

     

    How do I get the flasher to turn on when something out of the ordinary happens?

     

    Elementary! We use Grafana at work, so we just start a new Notification Channel with the WebHook type, which sends a request to turn on the flasher according to certain criteria. It turns off itself after a few seconds, so as not to pump up the atmosphere even more.

     

    How long did it take for all this mess? A couple of evenings, if not distracted. Plus half a day of working time to set up integration with the rest of the back-end systems.

     

    The technofan was a success, the team was useful, photographs of the assembly process are shown in the end.
