The model showcases mechanical details while fitting neatly on a desktop with its wooden base.\u003cbr\u003e.Hands-On Welding Project: Supplied as loose components, the kit includes metal wire framework, linkage parts, base components, and a control circuit. Users assemble the metal structure with a soldering iron, making it suitable for makers interested in wire bending, soldering, and mechanical assembly.\u003cbr\u003e.Motor-Driven Linkage: After assembly and power connection, the motor drives the crank and linkage mechanism, moving the horsehead up and down in a continuous nodding motion. The dynamic structure provides a visual demonstration of mechanical transmission and reciprocating movement.\u003cbr\u003e.Blue Ambient Lighting: Blue illumination shines through the transparent or semi-transparent structure during operation, contrasting with the metal wire framework. The blend of moving mechanisms and blue light adds an industrial, futuristic atmosphere for desktop display.\u003cbr\u003e.Maker \u0026amp; STEM Learning Project: The model demonstrates linkage transmission, crank mechanisms, and the conversion of electrical energy into mechanical motion. It can serve as a hands-on project for electronics, mechanical design, engineering study, maker spaces, and STEM learning environments.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e.Material: Metal\u003cbr\u003e.Product Weight: 160g\u003cbr\u003e.Package Weight: 500g\u003cbr\u003e.Product Dimensions: 16 x 8 x 15cm\u003cbr\u003e.Package Dimensions: 23 x 13 x 6cm\u003cbr\u003e.Packaging: Box\u003cbr\u003e.Age: 16+\u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Stirlingkit","offers":[{"title":"Default Title","offer_id":54860614566101,"sku":"SK3749235","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0134\/7446\/3808\/files\/stirlingkit-build-a-tiny-oil-pumpjack-for-your-desk-nodding-donkey-circuit-sculpture_5.jpg?v=1788867850","url":"https:\/\/www.stirlingkit.com\/pt\/products\/build-a-tiny-oil-pumpjack-for-your-desk-nodding-donkey-circuit-sculpture","provider":"Stirlingkit","version":"1.0","type":"link"}
