Occasionally, we find fun new electronic instruments in the wild and can’t resist sharing them with our readers. The item in question is the FNIRSI HRM-10 Internal resistance meter, which …read more Continue reading The FNIRSI HRM-10 Internal Resistance Meter
You know what they say. But it’s 2024, after all. Shouldn’t you be able to tune a fish by now? As [ChromaLock] shows us in the video below, it’s absolutely …read more Continue reading So You Can Tuna Fish
There’s an old joke about how to tell how tall a building is using a barometer. The funniest answer is to find the building owner and offer them a nice …read more Continue reading Temperature Measurement by Wire
A continuity tester, as found on most multimeters today, is a great tool for finding broken connections and short circuits. But once you’ve found a short, it’s up to you …read more Continue reading Op Amp Contest: Clever Continuity Tester Tells you Where the Problem is
For prototype electronics projects, most of us have a pile of resistors of various values stored somewhere on our tool bench. There are different methods of organizing them for easy …read more Continue reading Programmable Resistance Box
Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good …read more Continue reading How Many Wires Do You Need to Measure a Resistor?
You might think the probes in the picture are just funny looking alligator clips. But if you watch [tomtektest’s] recent video, you’ll learn they are really Kelvin probes. Kelvin probes are a special type of probe for making accurate resistance measurements using four wires and, in fact, the probe’s jaws …read more

You’d be hard pressed to find a hacker or maker who doesn’t have a soft spot for the tantalizing buzz and snap of a high voltage spark gap, but it remains the sort of project that most of us don’t take on personally. There’s a perceived complexity in building a …read more
There’s a problem with fuses. On the face of it, testing would seem to be a one-shot deal — exceed the rated current and see if it blows. But once you know the answer, the device is useless. If only there were a way to test fuses without damaging them. …read more
