This DIY soldering kit allows you to assemble an LED hourglass with a flowing light effect that visually simulates falling sand. After completion, it becomes a functional 1–99 minute countdown timer and a decorative electronic display for your workspace, study area, or maker space.\u003c\/li\u003e\n\u003cli\u003e【HANDS-ON STEM ELECTRONICS LEARNING EXPERIENCE】Go beyond traditional learning with a practical circuit-building project. During assembly, users can practice soldering skills, identify electronic components, understand circuit connections, and explore how timer circuits work. Designed for STEM students, makers, hobbyists, and electronics enthusiasts looking for a meaningful hands-on project.\u003c\/li\u003e\n\u003cli\u003e【ADJUSTABLE 1–99 MINUTE COUNTDOWN TIMER WITH VISUAL LED FLOW】Set countdown times from 1 to 99 minutes for study sessions, productivity intervals, experiments, workshops, or classroom activities. Unlike ordinary digital timers, the LED flow animation provides an intuitive visual experience, allowing users to observe the countdown process while adding an attractive electronic display element.\u003c\/li\u003e\n\u003cli\u003e【INTERACTIVE FLIP FUNCTION \u0026amp; OPTIONAL BUZZER CONTROL】The electronic hourglass features an interactive flip design that changes the LED flow direction while continuing the countdown without resetting. The optional buzzer alert can be enabled or disabled depending on the environment, making it suitable for quiet personal workspaces, educational activities, and maker projects.\u003c\/li\u003e\n\u003cli\u003e【INTERMEDIATE DIY SOLDERING PROJECT FOR MAKERS \u0026amp; STEM EDUCATION】This electronics kit includes both through-hole and surface-mount components, providing a more advanced soldering practice experience compared with basic soldering projects. Recommended for users with basic soldering knowledge or those completing the project with guidance. A rewarding STEM project for teens, students, hobbyists, classrooms, and electronics clubs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e PEMENOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Highlight:\u003c\/strong\u003e Circuit Project with LED Flowing Sand Effect, STEM Electronics Learning Kit for Teens, School, Class Group Activity, Makers\nCircuit Project with LED Flowing Sand Effect, STEM Electronics Learning Kit for Teens, School, Class Group Activity, Makers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e PEMENOL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PEMENOL","offers":[{"title":"Default Title","offer_id":48236048187543,"sku":"B0GQ4396Q7","price":36.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/1032\/2327\/files\/51fYmfiwW8L.jpg?v=1788880775","url":"https:\/\/tinkervanta.com\/products\/electronic-hourglass-soldering-prpject-kit-1-99-minute-countdown-timer","provider":"TinkerVanta","version":"1.0","type":"link"}
