In this article, I will show you how to build a simple Wireless Energy Transfer Circuit. It's really simple circuit made of 5 parts, even a beginner shouldn't have any problems with building this. Wireless energy transfer circuit I also improved it since my last video, made better secondary coils that work on larger/longer distances. Things you will need: 1. Transistor BD139 Transistor BD139 Or you can use these alternatives: BD135, BD137, 2N4921, 2N4922, 2N4923, BDW55, BDW57, BDW59. (You need only one, not all of them) 2. Foil capacitor 1nF 100V Foil capacitor 1nF 100V Voltage should be more than 16V, you should use this one because of its size (it will fit on PCB as we need it) Note that: 1000 means 1000pF = 1nF tags: Wireless Energy Transfer Circuit 3. Foil capacitor 4.7nF - 100V Note: 4700 = 4700pF = 4.7nF 4. Foil capacitor 100nF - 63V Note: 0.1 means 0.1uF here; 100nF 5. Resistor 5k6 Ohm, 0.5W Resistor 5k6 Ohm, 0.5W 6. And a 5x6 holes large piece of universal PCB. 5x6 hole...
