[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 ...

As I mentioned in my recent columns on the topic of adding pull-up or pull-down resistors to the inputs of unused or partially used logic gates and functions (see Part 1, Part 2, and Part 3), I was ...

Logic analyzer probing can be classified into two groups. The first group consists of the signals that were “designed in.” This means that signals that are to be observed were intentionally routed to ...

Hackaday reader [JumperOne] was in need of a logic probe that he could use to reliably test some tiny .5mm pitch IC pins. The probe that came with his oscilloscope was a bit too big and not near sharp ...

Well, I must admit to being flabbergasted. I think I can say without fear of contradiction that my “flabber” has rarely been so “gasted.” The cause of my current state-of-gast was the rapturously ...

When testing circuits with a logic probe, it is sometimes difficult to watch the LEDS on the probe to determine the logic state. With this probe the logic states are audible. This probe is designed ...
