The circuit was designed to create a handy logic probe that can show off the logic states for high, low and pulsing outputs with the use of CMOS 4001 integrated circuit. Logic Probe – a handheld probe ...

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 ...

We live in a day when it is very inexpensive to buy an oscilloscope, especially one with modest performance that hooks to a laptop. However, there was a time when even a surplus scope was out of reach ...

I took a Computer Logic Design class in college, so when I stumbled upon the Ksimus Circuit Simulator, I was intrigued. At the risk of waxing nostalgic, I remember what it was like to build circuits ...

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 ...
