Color:

Case for a voltmeter/ammeter circuit case, used for measuring the output of a solar panel. Uses a voltmeter/ammeter circuit and a 5.5mm x 2.1mm jack, both available on ebay. The circuit is supposed to work without a shunt for less than 10A, but I had to wire across where the shunt would be for it to work, adjusting the length of the wire to roughly calibrate the current meter. Another version without this issue can be found at https://www.myminifactory.com/object/voltmeter-ammeter-case-2-18226 Some of the parts used for the meter: http://www.taydaelectronics.com/hardware/dc-power/dc-power-jack-2-1mm-bulkhead-type-panel-mount.html http://www.ebay.com/itm/121284198811?var=420241522717&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 Printed with thermochromic grey/white ABS and clear blue PET+.
