A peek under the skin of the Tetris tie.

Maker and teacher Bill Porter had a very important task ahead of him. He had to impress more than 100 eighth graders at a STEM camp. He had already wowed them with an LED lab coat and an 8-bit tie, but they wanted to know what was next. So Porter invented the Tetris tie, a glowing LED tribute to the classic falling-blocks game.
It took Porter about four hours to get the working prototype up and running. The tie uses 80 LED pixels powered by a DigiSpark microcontroller. It cost about $50 in materials.
Showing ingenuity and the ability to work with parts on hand, Porter fashioned the tie itself from two pieces of card stock and a cheap clip-on tie. The clip-on feature is the nerdy icing on the geeky make-cake. “I plan to revisit the design and embed the strips directly into a fabric tie for long-term use,” Porter writes.
