I wanted to make the final product feel polished and not readily discernible as simple microcontroller-based device; instead looking like something more akin to the esoteric inventions of Nikolai Tesla or Thomas Edison. I built a protoboard to connect the three switches, two potentiometers, two antennas and two actuators with the Particle Argon board and battery in a fairly compact envelope. The enclosure was cut out of a piece of spalted maple with a black acrylic face plate and turned clear acrylic knobs for the potentiometers. The handles are two pieces of spalted maple connected to the enclosure with two copper tubes through which the motor wires are routed. The motors themselves get embedded in a hole inside of the handles.

The front face plate was laser etched with an image composed from a couple of different found diagrams - a pcb trace for a wireless device, the curvature of a magnetic field, a map of dowsing lines around the Stonehenge site and a figure from an article on "polarity therapy" first drawn by author Randolph Stone. Originally I also planned on placing either lights or an additional knob for a tuning capacitor on the plate but ended up with the five shown below. To make the interface a little less confusing I tried to make the control placement somewhat related to the etched image- the on/off is at the feet , low and high cut offs are on the left and right side of the figure, the emf/wifi mode is on the left ( near the pcb diagram) and the antenna selection is on the right.
