DC Watt Meter Case

prusaprinters

<p>I wanted a means to measure real time readings for voltage, current and power. &nbsp;My past solution was to work with two multimeters, one for voltage and one for current and just calculate the power reading. &nbsp;Using my multimeters this way tied them up from other uses. &nbsp;Since I like to measure voltage and current often, I decided to build a general purpose metering set-up.</p><p>The DC 100V 10A 1000W Digital Voltmeter Ammeter Wattmeter provided much of metering solution. &nbsp;This project takes that module and incorporates it into a case with connected and a power source. &nbsp;I've incorporated the watt meter module without its included surrounding bezel. &nbsp;The bezel just clips on, so can be easily removed.</p><p>The metering unit is powered by a LiPo battery and includes a battery charging circuit, as well. &nbsp;The battery is charged by a mounted USB Type C connector. &nbsp;The USB connection allows the unit to also be externally powered, too.</p><p>The DC Watt Meter module is readily available for purchase. &nbsp;I purchased my module from AliExpress for less than AU$13 from here:<br>https://www.aliexpress.com/item/4000111105839.html?spm=a2g0s.8937460.0.0.d5a72e0eQ5IA0d</p><p>Here is my 3D design. &nbsp;My design may match your needs, too.</p><p>My print is made in PETG 1.75mm Aurarum silver filament, with 0.2mm layer height and 15% infill on a PRUSA I3 MK3S printer.</p><p>I hope you can find this design useful, too.</p><p>Remember to leave me some feedback or even a tip to keep me enthused to make more of these drawings.</p>
