The Torlo was born from the innovative concept of harnessing a simple oscillating motor as a power source. A scavenged voice coil from a spare laptop HDD proved to be the perfect fit, boasting powerful magnets that could effortlessly propel a series of 3D printed gears. Building on the foundation laid by the previous Holo Clock, the Torlo's design was taken to new heights. The clock's intricate mechanism features a unique drive train where the voice coil resides at its center, driven by an attiny pulsing every two seconds. This precise timing allows the balance wheel to push a cam and ratchet, effectively turning the clock 2 seconds further with each pulse. Meanwhile, a simple yet elegant drive train powers the minute and hour rings, seamlessly displaying the time. The Torlo's construction is a moderately complex project due to its delicate printed parts, requiring a great deal of patience to assemble correctly. All components were printed using a 0.4mm nozzle at a layer height of 0.2mm - 0.25mm, necessitating careful calibration to prevent the gears from freezing in place.
