Diy Universal Component Tester

I've created a DIY Universal Component Tester. This tool is designed to accurately measure and verify the functionality of a wide range of essential electronic components, including transistors (NPN/PNP), MOSFETs, and op-amps etc. While commercial testers can be expensive, this self-built solution provides a reliable, all-in-one measurement device for my electronics bench.

Supplies

Step 1: Schematic Diagram

Circuits are categorise 5 circuits boards and one for voltage regulate and other 4 are the main component testers..

Step 2: PCB Design

These are the copper boards I used for this project, and I designed them by hand.

Step 3:

here the assembling part done and re-checking the connection with each and every part, so there will be no mistakes after finishing the project

Step 4: Project Completed

project is completed and working as expected.Thank you for checking out this project.
