Step 1: Materials...
(I give capacitors by using codes and values)
- BD139 Transistor / 1
- 5.1 K resistor (all resistors will work) / 1
- 220n or 224 Capacitor / 1
- 4.7n or 472 Capacitor / 2
- 1.5pF or 102 Capacitor / 1
- LED / 1
- 1N4148 Zener Diode / 1
- Jumper wires
- Cable for Coil
- 9V Battery and Clip
Step 2: Making Coils
Whatever... We need to make 2 coils, one for receiver and another for transmitter circuit. Receiver circuit need normal coil, no splice.
However the coil which is going to attached to the transmitter circuit is different. It needs a wire which is come out at the middle of the coil. This is the most important part otherwise the circuit may not work.
Step 3: Making the Transmitter Circuit
Step 4: Making the Receiver Circuit
Step 5: Result
Step 6: Few improvements and Version2 With 10000uF Capacitor
Step 7: Schematic
Note:I made it simpler this project not belongs to me. Just for entertainment and educational purposes only.
