Logic testers are simple but very helpful devices in testing digital circuits. A logic probe can be designed in many different ways. In this particular design, a combination of discrete and TTL logic ...

[Robert Morrison] had an ancient HP 545A logic probe, which was great for debugging SMT projects. The only problem was that being 45 years old, it wasn’t quite up to scratch when it came to debugging ...

A recent Design Idea in EDN magazine, “Logic Probe Uses Six Transistors” caught my eye because I had just pulled out an old logic probe purchased many years ago. It seems logic probes have fallen into ...
