Why You Shouldn’t Quite Forget The Moving Coil Multimeter

If you were to ask a random Hackaday reader what their most fundamental piece of electronic test equipment was, it’s likely that they would respond with “multimeter”. If you asked them to produce it, out would come a familiar item, a handheld brick with a 7-segment LCD at the top, a chunky rotary selector switch, and a pair of test probes. They can be had with varying quality and features for anything from a few dollars to a few hundred dollars, though they will nearly all share the same basic set of capabilities. Voltage in both AC and DC, DC …read more

From 1950s Multimeter to Internet Connected Clock

We’ve seen many clocks here over the years. Some of them are conventional, some esoteric. So it’s not often that we see something novel in the world of timekeeping.

Strictly speaking, [Giulio Pons]’s clock project isn’t new at all. He’s taken a broken multimeter from the 1950s, and with the help of an Arduino Nano and an ESP8266 module, converted it into a clock that indicates the time on the multimeter’s moving-coil meter. He’s wired the multimeter’s front panel controls to the Arduino to operate the thing, and given it a speaker to play alarm sounds. A PIR motion detector …read more

MacGyvering Test Lead Clips

Okay fellow Make-Gyvers, what do you get when you cross a peripheral power cable jumper, a paperclip, springs, and some 3D-printed housings? DIY test lead clips.

Test clips are easily acquired, but where’s the fun in that? [notionSuday] started by removing the lead connectors from the jumper, soldering them to stripped lengths of paperclip, bent tabs off the connectors to act as stoppers, and slid springs over top. Four quick prints for the housings later, the paperclip assembly fit right inside, the tips bent and clipped to work as the makeshift clamp. Once slipped onto the ends of their multimeter …read more
