After an adjustable time the sand is flattened out by two vibration motors and everything begins all over again.\u003c\/p\u003e\n\u003cp\u003eAt the heart of the sand clock are two servo motors driving a writing pen through a pantograph mechanism. A third servo motor lifts the pen up and down. The sand container is equipped with two vibration motors to flatten the sand. The electronic part of the sand clock consists of a Raspberry Pi Pico and an RTC\/driver board with a real-time clock, plus driver circuits for the servo motors.\u003c\/p\u003e\n\u003cp\u003eA detailed construction manual is available for downloading.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 135 x 110 x 80 mm\u003c\/li\u003e\n\u003cli\u003eBuild time: approx. 1.5 to 2 hours\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eIncluded\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e3x Precut acrylic sheets with all mechanical parts\u003c\/li\u003e\n\u003cli\u003e3x Mini servo motors\u003c\/li\u003e\n\u003cli\u003e2x Vibration motors\u003c\/li\u003e\n\u003cli\u003e1x Raspberry Pi Pico\u003c\/li\u003e\n\u003cli\u003e1x RTC\/driver board with assembled parts\u003c\/li\u003e\n\u003cli\u003eNuts, bolts, spacers, and wires for the assembly\u003c\/li\u003e\n\u003cli\u003eFine-grained white sand\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/Q48aRQ7KmXI\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eElektor Laser Head Upgrade for Sand Clock\u003c\/h2\u003e\n\u003cp\u003eThe new Elektor Laser Head transforms the Sand Clock into a clock that writes the time on glow-in-the-dark film instead of sand. In addition to displaying the time, it can also be used to create ephemeral drawings. The 5 mW laser pointer, with a wavelength of 405 nm, produces bright green drawings on the glow-in-the-dark film. For best results, use the kit in a dimly lit room. \u003cstrong\u003eWarning:\u003c\/strong\u003e Never look directly into the laser beam!\u003c\/p\u003e\n\u003cp\u003eThe kit includes all the necessary components, but soldering three wires is required.\u003c\/p\u003e\n\u003cp\u003eNote: This kit is also compatible with the original Arduino-based Sand Clock from 2017.
