The circuit is designed for a supply voltage of 120V. The printed circuit pattern is reproduced here larger then real life for clarity. It will need to be resized to the scale at the bottom of the image if you intend to transfer it to a board. The circuit functions as an on/off flip flop. Illuminate it with your remote once to turn it on, then again to turn it off.
