Build a Tiny Oil Pumpjack for Your Desk Nodding Donkey Circuit Sculpture

DIY Metal Wire Oil Pumping Unit Welding Kit with Motorized Linkage and Wooden Base, STEM Model

Features:

.Classic Oil Pump Design: This compact beam pumping unit features a tower, walking beam, horsehead, crank linkage, and counterweight. The model showcases mechanical details while fitting neatly on a desktop with its wooden base.
.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.
.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.
.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.
.Maker & 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.
