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 ...

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 ...

A simple PIC12F683 microcontroller was used to create a logic level tester which has the capability of measuring 5V TTL up to 24V PLC logic levels. A simple PIC12F683 microcontroller was used to ...

The E5394A soft-touch connectorless touch probes offer very low electrical loading for the company's logic analyzers. They require no adapter and reduce capacitive loading by 80% compared with other ...

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 ...

Test probes go a long way toward ensuring accurate, repeatable test results. Here's a look at how both active and passive test probes are evolving to match today's broadening oscilloscope bandwidths.

It looks like something out of the Matrix or the Dune movie – imagine this electric needle plunging into your flesh and injecting you with the Snow Crash virus. Or something. In any case, it’s more ...
