Jelly Jar Galvanometer
thingiverse
By referencing TOPS Science's baby jar galvanometer (http://www.topscience.org/activities_print/FreeDownload19.pdf), a simple current measuring method is demonstrated. To create this, I used a Trader Joe's Juice Sweetened Jelly Jar with two bent paper clips as axles, covered in tape and wound with 100 turns of 24 AWG wire. For the pointer, I printed an axle and inserted a small neodymium magnet (6mmx6mm) into the jar's designated hole. After connecting the wires, successful function was confirmed, and calibration is now underway.
