Automatic Watch Winder

In the realm of luxury timepieces and watch aficionados, an automatic watch is a testament to mechanical brilliance and precision. But like every sophisticated mechanism, it demands care and attention. Enter the "Automatic Watch Winder", a state-of-the-art device designed to keep your automatic watches running when not worn. At its heart is the efficient ATTiny85 microcontroller, impeccably driving a relay module to ensure regular winding. Its mission? To safeguard your timepieces and ensure they're always ready to wear – a blend of tradition and modern tech.

Disclaimer:

The "Automatic Watch Winder" is designed for enthusiasts who cherish their watches and understand the intricacies of automatic movements. Recognize its features and constraints. Prioritize safety during assembly and usage to avoid any unwanted incidents.

Potential Applications:

Luxury Timepiece Care: Ideal for those who rotate between their collection, ensuring each watch remains operational.
Travel Buddy: Taking a trip and want to wear different watches? The Automatic Watch Winder keeps them running back at the hotel.
Educational Tool: A hands-on method for budding engineers or horologists to understand automatic movements and basic electronics.

Building Guide - The Automatic Watch Winder:

Gather the Necessary Tools and Materials:

ATTiny85 microcontroller
18650 Battery and its holder
Relay module
Slide switch
Step-up module (to convert 3.7V to 5V)
Custom PCB
Soldering iron, solder, flux
Tweezers or small pliers

Assembly:

Prepare Your Workspace: Opt for a clutter-free, well-lit workspace. This ensures precision and safety.
Position the ATTiny85: Place the ATTiny85 on the custom PCB, mindful of the pin orientations.
Integrate the Relay Module: Solder the relay's control terminal to pin PB0 of the ATTiny85.
Power Management: Connect the 18650 battery to its holder. Attach the holder's outputs to the step-up module's input. Once you achieve a 5V output, connect it to the ATTiny85's VCC and GND.
Add a Switch: To turn your winder on or off, solder the slide switch between the step-up module's output and the ATTiny85's VCC.
Programming the ATTiny85:
Breathe life into the "Automatic Watch Winder" by uploading the provided code to the ATTiny85. This code governs the relay module, ensuring the motor winds your watch at regular intervals. Ensure you're equipped to program the ATTiny85, whether via the Arduino IDE or another suitable environment.

Conclusion:

Marrying the classic world of horology with modern-day tech, the "Automatic Watch Winder" epitomizes the synergy of tradition and innovation. Embark on this assembly voyage with a mix of creativity, technical flair, and the right components to craft devices that amaze and serve.

Code

Arduino

// Define pin for the relay
const int relayPin = PB0;

// Define time intervals
const long fifteenMinutes = 15L * 60L * 1000L;  // 15 minutes in milliseconds
const long fiveSeconds = 5L * 1000L;           // 5 seconds in milliseconds

// Variable to keep track of the last time the relay was triggered
unsigned long lastTriggered = 0;

void setup() {
  // Initialize the relay pin as an OUTPUT
  pinMode(relayPin, OUTPUT);
  // Start with the relay turned off
  digitalWrite(relayPin, LOW);
}

void loop() {
  // Get the current time
  unsigned long currentMillis = millis();

  // Check if 15 minutes have passed since the last trigger
  if (currentMillis - lastTriggered >= fifteenMinutes) {
    // Turn on the relay
    digitalWrite(relayPin, HIGH);
    // Update the last triggered time
    lastTriggered = currentMillis;
    // Wait for 5 seconds
    delay(fiveSeconds);
    // Turn off the relay
    digitalWrite(relayPin, LOW);
  }
}
