Some of our readers will remember the Thermochromic Urinal that we featured on Geeky Gadgets a while back. Now, we have the Thermochromic clock, which uses similar technology but in a more practical and visually appealing way.
The Thermochromic clock was developed by Che-Wei Wang and Taylor Levy of CW&T. This innovative clock is controlled by an Arduino, a popular open-source electronics platform. Have a look at the video of it in action below.
Thermochromic Clock is a 4-digit 7-segment timepiece. Each segment in the display is made with a length of nichrome wire and then covered by a thick layer of black thermochromic paint. Time is displayed by applying voltage to the nichrome wire. As the wire sustains an electric current, it heats up the surrounding thermochromic paint, causing it to become transparent.
How the Thermochromic Clock Works
The core technology behind the Thermochromic clock involves the use of thermochromic paint, which changes color in response to temperature changes. Nichrome wire, known for its high electrical resistance and ability to withstand high temperatures, is used to heat the paint. When an electric current passes through the nichrome wire, it heats up, causing the thermochromic paint to become transparent and reveal the underlying segments that form the digits of the clock.
This process is controlled by an Arduino microcontroller, which precisely regulates the current to each segment of the display. The Arduino can be programmed to display the time in various formats, making the clock not only functional but also customizable. The use of thermochromic paint adds a unique visual element, as the digits appear to fade in and out smoothly, creating a dynamic and engaging display.
Applications and Future Potential
The Thermochromic clock is more than just a timepiece; it represents a fusion of art and technology. Its unique design and functionality make it a conversation starter and a piece of modern art. Beyond its aesthetic appeal, the technology behind the Thermochromic clock has potential applications in various fields.
For instance, thermochromic materials could be used in temperature-sensitive indicators for industrial applications, where visual cues are needed to monitor equipment temperatures. In consumer electronics, similar technology could be used to create dynamic displays that change based on user interaction or environmental conditions.
Moreover, the integration of Arduino opens up endless possibilities for customization and expansion. Hobbyists and developers can modify the clock’s code to add new features, such as alarms, countdown timers, or even integration with smart home systems. This flexibility makes the Thermochromic clock an excellent project for those interested in exploring the intersection of electronics, programming, and design.
