these $1 solar garden lights are a marvel of engineering. eliminating the CdS photocell and switch, the parts count is reduced to 5: solar cell, battery, YX8018 boost converter, LED, and tiny inductor that looks like a resistor. I'm about to attempt to desolder the LED, add a length of wire to it, and attach the functional assembly from 2 of these lamps to the front and back of my hat, to be my head- and taillights for the Kinetic race.
it's amazing how one can buy complete products for a fraction of the component cost.
