6 inch x 4 1/4 inch led night light with a Fibonacci spiral inspired shell pattern that is back-lit with (3) 10mm led's. Uses a 12 volt DC wallwart power supply and (1) 68 Ohm current limiting resistor. Female power jack is 2.1mm. (1) small slide switch is needed. Wire resistor and led's in series. Uses 4-40 x 1/4" screws to assemble. Keep wires close to edges so that they can't be seen through slots.
Sorry to those that downloaded this. The front was upside down. It is correct now. Thanks.
I would change the 68 ohm resistor for a 470 ohm. Led's started to dim over time .
