Hackster.io member ekaggrat has created a unique clock which writes the time in sequins. Built using an Arduino Nano R3 micro-controller together with a variety of 3D printed components, the project is classed as requiring an advanced skill set and has been showcased on the Hackster.io website. Check out the video below to see it in action.
Inspiration and Development
“This project is a continuation of my quest to build a robotic clock which can write and rewrite the time continuously day in and day out and keep going doing it. My first attempt with doodle clock was a failure due to the marker drying up and the second attempt with doodle#2 failed as the display got scratched very soon.”
The inspiration for this clock came from an unexpected source—ekaggrat’s daughter’s t-shirt, which featured a pattern-changing sequin cloth. This innovative idea led to the creation of a clock that uses sequins to display the time. After sourcing some stock fabric from a vendor, ekaggrat determined the size of the clock based on the minimum resolution of the cloth. The fabric consists of circles of 5mm stitched 3mm apart, which provided a unique challenge in terms of design and functionality. Additionally, the size of the clock was limited by the printer bed size of 245x170mm.
Technical Details and Challenges
The clock’s mechanism involves a series of intricate movements controlled by the Arduino Nano R3 micro-controller. The sequins are flipped to display the correct time, and this requires precise control and coordination. The use of 3D printed components was crucial in achieving the desired accuracy and reliability. Each component had to be meticulously designed and printed to ensure smooth operation.
One of the significant challenges faced during the development was ensuring the durability and longevity of the display. Unlike previous attempts that failed due to the marker drying up or the display getting scratched, the sequin-based display offers a more robust solution. However, it still required careful consideration of the materials and construction techniques to ensure it could withstand continuous use.
The project not only showcases ekaggrat’s technical skills but also highlights the potential for creative and unconventional approaches to common problems. By drawing inspiration from everyday objects and combining them with advanced technology, ekaggrat has created a truly unique and functional piece of art.
