Thermocouples Made From Ordinary Copper and Steel Wire. Thermocouple loop made into a coil can deflect a compass needle.
DC current probe meters are certainly not found everywhere but a compass can be used to indicate current flow by making the thermocouple loop into a coil. This coil uses 5 feet of copper wire but the use of 12 gauge keeps the resistance low enough for observable current to flow. The compass needle is most easily deflected when it is perpendicular to the coil axis as shown in the above picture. A piece of tissue paper was placed over the mirror in the compass case to eliminate lighting glare while taking the photographs. A flame held under one junction will cause an easily observable deflection of the compass needle. When a flame is held under the opposite junction, the compass needle will deflect in the opposite direction. The magnetic field of the earth pulls on the compass needle like a spring and makes it somewhat difficult to deflect.

Gear Wheel Designer software creates a variety of clock gear types & generates the g-code. The units can be metric or imperial, the sequence of operations can be specified, & it will also cut spokes. Three curves are used above & below a gear's base circle to design cycloidal gears. Cycloid. Epicycloid, the shape above the base circle. Hypocycloid, the shape below the base circle.
