The battery and other internals are not touchable without this hack, consequently the manufacturer may have selected a lightweight insulation. it doesn’t fulfill the requirements that are needed between line voltage and touchable parts. In many European countries (with reversible Schuko plug), it means the battery may be connected directly to 230 V live voltage or to the 0 V neutral, depending on which way you plug it in the wall outlet.Įven if the UPS has an isolating transformer, the isolation is probably functional only i.e. liked Ultrasonic Clothes Dryer.Indeed! I have seen UPSes where the battery is directly connected to one of the AC lines.

The project box is quite small, and to get everything to fit sourced the Lithium Ion battery from a Bluetooth headset. Now the device will perform what amounts to a hardware reset about 700ms after powering on or changing between inductance and capacitance measuring functions.

The code is mostly unchanged, but some calibration routines became necessary after noticed bugs in the behavior after power cycling. The core of the original design remains the same, with slight modifications to drive a different model of character LCD.

What he came up with is the battery-powered LC meter you see above. The only problem was that he didn’t want to be tied to a bench supply or power outlet, which meant a bit of auxiliary design was in order. needed an LC meter and decided to use a tried-and-true design to build his own. If you’d like to build yourself a 6.5-digit DMM to go with our LC Meter, consider this one which even has a home-built ADC.Ĭontinue reading “Build-It-Yourself LC Meter” → Posted in how-to, Tool Hacks Tagged atmega328p, how-to, lc meter, test and measurement PIC LC Meter Improvements Add Li-Ion Battery And Charging Circuitry The finished meter looks incredible! If you want to build one for yourself, he’s put all of the files up on GitHub, and we highly recommend you check out his first video after the break. if you have to sort a bag of cheap capacitors looking for specific value), he’s even developed a desktop program to save you some trouble! For times when you need to measure a lot of parts (e.g.

However, he didn’t just release a design, in a series of videos he goes through the theory of the device’s operation explains the design of the circuit, firmware, and case and shows you how to put it all together. ’s design is all through-hole, so even just assembling one would be a great exercise for someone getting started in electronics. On Hackaday.io, has developed an open-source LC meter to allow you to build your own tool to measure inductance and capacitance. Every toolbox needs at least one DMM, but most have an crucial limitation- they can’t measure two of the fundamental electrical quantities: inductance and capacitance. Even a bargain-bin DMM will happily measure voltage, current, and resistance check continuity and may even have a mode to measure transistor gain. A basic digital multimeter (DMM) is usually the first measurement tool the aspiring electronics tinkerer buys.
