LED art

LEDs (light emitting diodes) are very inexpensive to purchase and have become a new way to make street art.

Their other uses include: A typical blinky is a small plastic two-piece cylinder wide enough to accept a button cell battery with a small etched circuit board on the face and threads on the open end, paired with a cylinder cap which screws on to seal and secure as one.

Modern blinkees are more likely to use a battery case that opens with a small eyeglasses type screw and a push button on/off switch.

A clear plastic conformal coating material such as silicone, acrylic or epoxy protects the fragile LEDs on the exposed front of the board.

Common shapes (besides the classic small circle) are stars, hearts, flowers, flags, animals, holiday symbols (like Halloween jack-o-lanterns), and sports team logos.

In early 2007, there was a bomb scare in Boston, Massachusetts in the United States caused by a guerrilla marketing campaign.
