Picture of Wireless Power Using UMK8
Ok, this project is not any research for serious Wireless Power, with high efficiency, it is just some free time Microcontroller project, and all the variable and setting in this project is being obtain through try and error, and it doesn’t involve any complex calculation for electromagnetic stuff. Do comment if you have any idea or better way to improve the system.

Step 1:

Picture of
Basically, I have a Sun Jar, which is a solar powered lamp, that it is like you could store the sunlight in the jar. Charge it up at daytime, and use the light at night. (you can Google “Sun Jar” for more information)

if you add more turns that means you add resistance and need more power to use it if you remove turns that means that you decrease the resistance and the wire can get very hot and burn or short out the circuit so you can look for a formula for it to find the right amount of turns.

Where Vs - Secondary coil induced voltage,
Vp - Primary coil induced voltage,
Ns - No. of turns in secondary coil &
Np - No. of turns in primary coil.
The voltage can be stepped up if Ns> Np.
The voltage can be stepped down if Ns< Np.
