Make Your Own Logic Tip (includes Printed Circuit Board)

In this video tutorial we will see how to make a logic tip, on a printed circuit, with the integrated circuit sn7404, a 7-segment display.

Step 1:

In this video tutorial we will see how to make a logic tip, on a printed circuit, with the integrated circuit sn7404, a 7-segment display, the transistor 2n3904 and other electronic components, from the defunct cekit magazine, but with a pcb design of our own.

What is a logical tip?

A logic probe is an instrument that detects the presence of high and low levels, or pulse signals at any point in a digital circuit.
