DIY Acoustic Levitation Electronics Makes Learning Kits for Science and Small Experimental Standing Waves

在 Instagram 查看这篇帖子 physicsfun (@physicsfun) 分享的帖子 DIY Acoustic Levitation Electronics Makes Learning Kits for Science and Small Experimental Standing Waves Features: .Feature：Working voltage：12V; Size：42mm X 26mm X 53mm(H); Suspended object: foam ball; Button K1 K2 not support (Reserved function) ..The new PCB is changed to octagon.LED (red) power indicator，while LED (yellow and green) ultrasonic suspension indicator.The output voltage amplitude is 24V, measured with a multimeter, and the AC file is about 33.9V.The suspended foam ball is stable, Ultrasonic probes are matched to ensure that they float successfully every time.It can still levitate after lying down. It has strong levitation ability.and the strong hands-on ability can provide the self-welding of the loose parts..Mini Acoustic Levitator: This is a mini ultrasonic levitator device that can suspend foam balls. The device is composed of a MCU STC15W, a driving chip TC4427EOA and two 16mm 40KHz ultrasonic probes. Mainly used for students or DIY electronics enthusiasts to learn about ultrasonic standing wave levitation..Working principle:Ultrasonic standing wave levitation is through the existence of a certain distance between the ultrasonic transmitting end and the reflecting end (or another transmitting end) (called the distance of the resonant cavity), the transmitted wave and the reflected wave (or another sound wave) are continuously superimposed and finally form a stationary Wave, the sound wave force received by the object at the node of the standing wave overcomes the effect of gravity and finally achieves the effect of levitation..Note: Harmonics are easy to be generated after ultrasonic superposition, resulting in squeaking sound, which can be solved after the distance is extended, but it will lead to poor suspension ability. Specifications: .Color: As Shown.Material: Electronic Components + Copper + Resin.Product Dimensions: 4.2 x 2.6 x 5.3cm.Product Weight: 200g.Package Dimensions: 10 x 10 x 10cm.Package Weight: 300g.Packing: Carton Box Package Content: .1 x Mini Acoustic Levitation.1 x 12V DC Power Adapter.1 x Small Net Spoon

While EngineDIY offers some eco-friendly product options, their overall sustainability practices lack transparency and comprehensive reporting. Their packaging and shipping practices show room for improvement, and they provide limited information about their supply chain ethics. The company has made some initial steps toward environmental initiatives but lacks clear targets and measurements. Their recycling program for used parts is commendable, though their overall environmental impact tracking needs significant development.
