  • since it's hard to find the exact specs of inductor here, can i use a toroid inductor? https://www.bukalapak.com/p/elektronik/komponen-elektronik/84bjmh-jual-induktor-ring-coil-470-uh-3a

  • https://images.app.goo.gl/1eWBwa143gdrzjnFA inductor is like that

  • i use a tiny neodymium magnet, 3x12mm. the inductor is really hot, but the magnetic field is really weak. i only feel a vibration coming out from the inductor. the inductor is really hot even though b

  • okay alex, i already got one more mosfet. but there's a trouble. i already followed your tutorial, it works until "the comparator circuit". but "levitating the magnet" doesnt work. i got another model of inductor, but it has the same specs, 1mH. here are the symptoms: i can feel some vibration coming out from the inductor, and the inductor is really hot, more than the mosfet. is it normal?

  • i already checked out the blog, but i got some question to discuss here. are the levitation circuit and the wireless power transfer different circuit? so do we need 2 mosfet for all circuit? or can we combine them into a circuit which only needs a mosfet? thank you

  • Hi alex! Thanks for creating this project. Soon im going to create this project. But there are some questions for you. 1. why do we need a square wave signal? 2. In the end of article, you said that it's better to use a ne555 to generate a square wave signal to increase the efficiency. How do we connect the square wave signal? Thanks for your help
