Nixie tube clocks offer a unique blend of vintage aesthetics and modern functionality, making them a captivating DIY project for enthusiasts of all skill levels. Originating from the mid-20th century, these retro-inspired timepieces have seen a resurgence in popularity, attracting hobbyists and tech enthusiasts alike.

In this guide, we'll explore creating your own Nixie Tube Clock using HTML, CSS, and JavaScript. Whether you're a beginner looking to delve into the world of web development or an experienced coder seeking a new challenge, this step-by-step tutorial will walk you through crafting a fully functional digital clock with a nostalgic twist.

Source Code

Step 1 (HTML Code):

To start, create a basic HTML file with elements for the clock display and any additional features you want to include, such as settings or animations.

Let's break down the HTML code:

1. <!DOCTYPE html>: This declaration specifies the document type and version of HTML being used, which is HTML5 in this case.

2. <html lang="en">: This tag defines the beginning of the HTML document, with the "lang" attribute specifying the language as English.

3. <head>: This section contains meta-information about the document, such as character encoding, viewport settings, and the title of the page.

  • <meta charset="UTF-8" />: Sets the character encoding to UTF-8, allowing for the display of a wide range of characters.
  • <meta http-equiv="X-UA-Compatible" content="IE=edge" />: Instructs Internet Explorer to use the latest rendering engine available.
  • <meta name="viewport" content="width=device-width, initial-scale=1.0" />: Defines the viewport settings for responsive design, ensuring the page adapts well to different devices.
  • <title>Nixie Tube Clock</title>: Sets the title of the webpage to "Nixie Tube Clock".
  • <link rel="stylesheet" href="styles.css" />: Links an external CSS file named "styles.css" to the HTML document for styling purposes.

4. <body>: This section contains the content of the webpage visible to users.

  • <svg id="noise-svg">: Defines an SVG element with the ID "noise-svg", which seems to add a background texture using filters defined within.
  • Within the <div class="clock off">, there's the main structure of the Nixie Tube Clock, including various elements like pipes, displays, and buttons.
  • <script src="script.js"></script>: Links an external JavaScript file named "script.js" to the HTML document for adding interactivity and functionality to the webpage.

Step 2 (CSS Code):

Use CSS to enhance the visual appeal of your Nixie Tube Clock. Style the digits, background, and any other elements to achieve the desired retro aesthetic.

Let's break down some key parts:

1. @import url('https://fonts.cdnfonts.com/css/lcd');: This imports an LCD font from a URL.

2. box-sizing: border-box;: This makes sure that padding and border are included in the element's total width and height.

3. html, body { ... }: These rules define styles for the html and body elements. They set the height to 100% and hide overflow.

4. body { ... }: This section sets up the clock display. It uses flexbox to center the clock vertically and horizontally. It also defines colors and variables for various parts of the clock.

5. #noise-svg, #noise-rect { ... }: These rules define styles for elements used to create noise effects.

6. .clock { ... }: Styles for the clock container. It positions the clock relatively and uses flexbox for alignment.

7. .shadow { ... }: This defines the shadow of the clock.

8. .pipe-accents { ... }: Styles for pipe accents around the clock.

9. .display { ... }: Styles for the clock's display area.

10. .glass-tube { ... }: Styles for the glass tube around the clock.

11. .hex { ... }: Styles for the hexagonal shape around the clock.

12. @keyframes flicker { ... }: This defines a keyframe animation called "flicker".

13. .tube-base-container { ... }: Styles for the tube base container.

14. .tube-base { ... }: Styles for the base of the tube.

Step 3 (JavaScript Code):

Add JavaScript to bring your clock to life. Use functions to control the display of time, handle user interactions, and update the clock in real time.

Here's a breakdown of what the function does:

1. const now = new Date();: Creates a new Date object representing the current date and time.

2. let hours = now.getHours();: Retrieves the current hour from the Date object.

3. const minutes = now.getMinutes().toString().padStart(2, '0');: Retrieves the current minutes from the Date object, converts it to a string, and ensures it is always two digits by padding it with a leading zero if necessary.

4. let amPm = hours >= 12 ? 'PM' : 'AM';: Determines whether it's morning (AM) or afternoon/evening (PM) based on the current hour.

5. Adjust the hours to be in 12-hour format and ensure it's always two digits by padding with a leading zero if necessary.

6. Construct a string (timeStr) representing the time in the format "HHMM" (hours and minutes).

7. Retrieves the current month, day, and year, ensuring they are always two digits, and constructs a string (displayStr) representing the entire date and time in the format "HHMMAMMMDDYY".

8. Iterates over the digits of the displayStr and updates corresponding elements in the HTML with IDs like "char01", "char02", ..., "char111", "char112".

9. Finally, the function is called initially to update the time and date immediately, and then it's set to run every 60,000 milliseconds (or every minute) using setInterval() to keep the displayed time and date up-to-date.

function updateTimeAndDate() {
  const now = new Date();
  let hours = now.getHours();
  const minutes = now.getMinutes().toString().padStart(2, '0');
  let amPm = hours >= 12 ? 'PM' : 'AM';
  if (hours > 12) {
      hours -= 12;
  } else if (hours === 0) {
      hours = 12;
  }
  let timeStr = hours.toString().padStart(2, '0') + minutes;
  if (timeStr.startsWith('0')) {
      timeStr = ' ' + timeStr.slice(1);
  }
  let month = (now.getMonth() + 1).toString().padStart(2, '0');
  let day = now.getDate().toString().padStart(2, '0');
  const year = now.getFullYear().toString().slice(-2);
  if (month.startsWith('0')) {
      month = ' ' + month.slice(1);
  }
  if (day.startsWith('0')) {
      day = ' ' + day.slice(1);
  }
  const displayStr = timeStr + amPm + month + day + year;
  for (let i = 0; i < 12; i++) {
      document.getElementById('char' + i + '1').textContent = displayStr[i];
      document.getElementById('char' + i + '2').textContent = displayStr[i];
  }
}
updateTimeAndDate();
setInterval(updateTimeAndDate, 60000);
