Wireless Power Transmitter - Circuito electronic

Really Wireless Power Transmitter technology is increasingly in our daily lives. The main scientist in the area of power transmission is Nikola Tesla, he created several devices for Wireless Power Transmitter. Today many devices for Wireless Power Transmitter has its electronic circuit based on the ideas of Tesla.

Make a Simple FM Transmitter

This circuit uses a small microphone to capture the sound and some transistors to generate radio waves that can be picked up by a FM receiver like a car stereo.

How it works:

From left to right, the first part is the microphone and some resistors to get it working. Next we have a capacitor and the first transistor, this amplifies the sound from the microphone so that it can be loud enough to work with. The last part, there is a transistor, a coil and some capacitors. This part generates the radio waves and combines them with the sound from the mic to transmit it thru the antenna.

Make a Simple FM Transmitter

The coil is made with about 9 turns of wire, use a pencil to get the right diameter for the coil. The capacitor with the arrow is called a trimmer capacitor, it has a small screw to adjust the value, we'll use it to tune a certain frequency or station to transmit on.
