Voltmeter/Ammeter Case - 1

cults3d

Case for a Voltmeter/Ammeter Circuit Case, Designed Specifically for Measuring Solar Panel Output. This innovative case utilizes a voltmeter/ammeter circuit and a 5.5mm x 2.1mm jack, both readily available on eBay. The circuit is engineered to function seamlessly without a shunt for current levels below 10A, however, I had to modify the wiring by adding a connection where the shunt would be located, adjusting the wire length to achieve an approximate calibration of the current meter. For those interested in resolving this issue, a revised version can be found on Thingiverse at http://www.thingiverse.com/thing:328366. Key components used for the meter include: * DC Power Jack 2.1mm Bulkhead Type Panel Mount from Tayda Electronics (http://www.taydaelectronics.com/hardware/dc-power/dc-power-jack-2-1mm-bulkhead-type-panel-mount.html) * eBay item #121284198811, available at http://www.ebay.com/itm/121284198811?var=420241522717&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 The case was printed using thermochromic grey/white ABS and clear blue PET+.
