Greetings, everyone!

Are you in search of an affordable solution for a function generator? If purchasing one isn't your preference, you can embark on this exciting tutorial to create your own. A function generator proves to be an essential tool for numerous projects. In my case, I utilized it to construct wireless power transmission modules. Through extensive online research, I discovered a remarkable and remarkably simple method to build one.

Central to this project is the versatile IC ICL8038, which offers an output of sine, saw, and square waves within a frequency range spanning from 150Hz to 150KHz.

Your support and votes for Remix 2.0 would be greatly appreciated.

Let's commence our journey to build this amazing function generator together!

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

Presenting the circuit diagram for our function generator project. Follow the provided circuit layout, but instead of the 1M resistor, substitute it with a 2M resistor. If you prefer, you can even create a PCB (Printed Circuit Board) for this circuit. If you require the Eagle file for this project, kindly leave a comment expressing your interest, and I will gladly upload it for you.
