Can I read TTL/CMOS Logic Probe Circuit Design on EtoBox?

TTL/CMOS Logic Probe Circuit Design by John Abrahim is a document available to read on EtoBox.

What is TTL/CMOS Logic Probe Circuit Design about?

The document summarizes two design ideas: 1) A low-component-count logic probe that uses two op-amps and some resistors and diodes to detect logic levels in TTL and CMOS circuits. It gets power from the circuit under test and uses LEDs to indicate high and low logic levels. 2) A simple circuit that functions as a photovoltaic module simulator using a DC voltage source and transistors. It allows controlling the short circuit current and open circuit voltage to simulate different module characteristics.
