Introduction: How to Make a Simple Wireless Charging
Inductive charging (also known as wireless charging) uses an electromagnetic field to transfer energy between two objects through electromagnetic induction. ... Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.
Step 1: Video
see this video if you like it you can make it
Step 2: Make a Simple Wireless Charging
To make a sample wireless Charging we need
1- NPN transformer (2N2220A)
2- 1Kohm resistor ()
3- copper wire
4- LED
5- 1.5v battery
Step 3: Coils
make a coil two coils
the first coil make 15 Turns and make a center tap then make more 15 Turns
the second Coil make 30 Turns
Step 4: Circuit
draw the circuit such as the photo
Step 5: Other
for test connect an LDE to the secondary coil and test it
