3D-printed digital clock accommodates 24 analog clocks

Arduino GroupJanuary twenty fifth, 2023

Clocks are incredible technique of inventive expression, as they serve a sensible function and due to this fact have a motive to exist, however aren’t restricted to pure performance. As such, we see many attention-grabbing clock designs. However ihart’s 3D-printed digital clock constructed from 24 particular person analog clocks takes the proverbial cake.

When noticed from a distance, this clock appears to be like prefer it accommodates giant seven-segment shows. Nevertheless it really shows the numerical digits of the time utilizing the 2 palms of 24 particular person analog clocks. These analog clocks don’t present the time, however as a substitute kind the segments that make up the “digital” digits. The choreographed dance of the clock palms because the time modifications is mesmerizing and the sheer complexity of the system ought to excite even probably the most stoic engineers in our viewers.

Every of the 24 analog clocks has two palms that transfer independently, so this clock requires a complete of 48 stepper motors. Every hand additionally requires a Corridor impact sensor for locating its residence place. Whereas there have been many different potential options, ihart selected to make use of one Arduino Nano board for each analog clock. That signifies that every Arduino controls two stepper motors. To simplify wiring and energy distribution, ihart designed a customized PCB to host every of these 24 Arduino boards. A twenty fifth Arduino Nano, paired with an RTC (real-time clock) module, coordinates the operation of the opposite 24.

All the mechanical parts of the clock have been 3D-printed. The design is considerably modular to maintain the distinctive half rely down, which signifies that this might be expanded into a bigger show. However at the same time as it’s, the clock could be very spectacular.
