Collaborate Disseminate
Cross-pollination between different industries can yield interesting innovations, and a few years ago [John Wiltrout] developed some non-slip meter probe adapters. He recently used our tips line to share some …read more Continue reading Dentist Tool Hardware Inspires Non-Slip Probe Tips
Among his many interests, [Dave Jones] likes test and measurement equipment. He recently posted a few videos on his EEVblog exploring the reasons why Fluke voltmeters are so expensive. In the …read more Continue reading Fluke DMM Hack Adds One Digit to Model Number
When a fine piece of lab instrumentation crosses your bench, you’ve got to do your best to put it to work. But even in the highest quality devices no component lasts forever, especially vacuum tubes. For some vintage instruments with vacuum fluorescent displays, that means putting up with less-than-perfect digits in order to get that sweet, sweet precision.
