In contrast, this Raspberry Pi Pico-controlled sand clock shows the exact time by “engraving” the four digits for hour and minute into the layer of sand. 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 src=\"https:\/\/www.youtube.com\/embed\/Q48aRQ7KmXI\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/RSsmcME9Gdc\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"Elektor Labs","offers":[{"title":"Default Title","offer_id":47310512226636,"sku":"20679","price":39.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0626\/6280\/3788\/files\/sand-clock-kit-based-on-raspberry-pi-pico20679-545580.jpg?v=1742227178","url":"https:\/\/www.qavlunxerzi.info\/products\/elektor-sand-clock-for-raspberry-pi-pico","provider":"Elektor","version":"1.0","type":"link"}
