Solar-powered, electronic earrings that spin in strong light. Unique and guaranteed to provoke conversation.
For all genders. Especially for maker, green, steam-punk, techy, early-adopters.
In direct sun, they spin vigorously, twirling back and forth at about 60 rpm. Outdoors in the shade, or on an overcast day, they twitch every ten seconds or so. Indoors, they require strong light (1000 lux), typical of a well-lit office or retail space, and then they twitch every minute or so.
Crystalline, solar cells. Chrome plated motor with super-magnets. Dark purple circuit board. Hints of tin, gold, red, black, and yellow in the components. Suspended by nylon thread from a platinum plated hook. No batteries.
Not enough power to hurt you. No glass or sharp edges. Free of lead (Pb.) Green electronics made using low-toxicity chemicals. Low power of 1.5 volts: free of shock and fire hazard.
Strong, but not as robust as metal jewelry. They usually survive being dropped, but not being stepped on. If yanked, the nylon thread should pull off the motor before it hurts your ear.
They will last many years, depending on how often you wear them, in what light. The parts do not wear out, except for the motor. The motors are pager motors, rated about 2000 hours MTTF for nearly continuous spinning. This means that these earrings, in a sunny, dry desert on the equator, typically last about six months. Worn in more typical fashion, they might last a lifetime, but a few may fail within a year or two.
