Segments rise from a sheer white surface to reveal the time in this papercraft digital / analog clock build by [Jacky Mok].
New York-based designer [Alvin Aronson] is responsible for the original, titled “D/A Clock,” which he built as a student at RISD using Corian instead of paper. [Aronson]‘s design is also massive in comparison. It measures one meter wide by a half meter tall. Without access to either a 3D printer or to a laser cutter, [Jacky] instead reduces the scale of his interpretation and relies on cardstock as the primary construction material. His experience with papercraft typography leads to a design that anyone with an Exacto knife and a slice of patience should find manageable. [Jacky] ignores the Exacto option, however, and cuts his pieces with a tool we saw earlier this year: the Silhouette Portrait.
The clock’s electronics include an Arduino Uno, a servo motor controller, twenty-eight servos and an RTC breakout board that handles timekeeping. Each servo drives its own segment by sliding a paperclip forward or backward inside a small, hollow aluminum rod. Though we’re still holding out for a video of the finished papercraft build, you can watch a video of Aronson’s original clock after the break and see what inspired [Jacky's] design.
Need another clock to envy? Last month’s build by [ebrithil] uses twenty-two servos to individually spin the segments. If you prefer that your clocks light up, [Aaron's] o-scope transformation has you covered.
