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.

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

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

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

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