Last Christmas (2014) I decided to make light-up cards. I've made Christmas cards in the past, but none with live circuitry.
One of four card designs.
The card uses a simple circuit. The circuit consists of a 3 volt coin battery, momentary switch, resistor, and 5mm LED.
The finished product. Press and hold the button to make the nose light up.
I made a total of four card designs, shown below.
A certain red-nosed reindeer. This is the design shown above.
My take on a traditional Christmas symbol.
The three wise men, following a star.
Night-vision Santa Claus.
