Function Generator

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!

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.

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.

Eagle Files

Power up your function generator, and it's ready to be deployed.
