Need a Cheap Function Generator ? , Don't Wanna buy it....? .... you can make one from this tutorial..... A function generator is one's need.... In most of the project...... I made it to use it to make wireless power transmission modules..... .. After searching a lot on Internet I came up with the best ever and the easiest ever to build....
The Heart of this project is IC ICL8038.
It also has a frequency range of 150Hz to 150 KHz in the output of sine, saw, and square waves.

Step 1: Material and Components Required
Let's browse what we all need.
1. 3x10K Potentiometer.
2. 1x1K variable resistor(I've used a trimpot one) .
3. 1x4.7K variable resistor .
4. IC ICL8038.
5. 1xTransistor 2N1613.
6. 1xDC Jack.
7. Wire Terminal.
8. 1x 4 terminal rotary switch.(or any sort of switch for tuning, due to lack of availability I've use dip switches)
9. 15k and 2M Resistor.
Step 2: THE CIRCUIT
Here's the Circuit for the function generator, make the circuit as given but in the place of that 1M resistor, use a 2M one....... You can also make pcb for the given circuit..... And if you need the eagle file..... Please comment for it...... And I will upload it......
Step 3: Ready to Serve
That's all you need to do.... To make your own function generator..... Please... Share....... And if you like this...... Add this to your favorites...... :)
Step 4: Updates
Added github link to cad files
