EL wire, or electroluminescent wire, is a flexible wire coated in phosphor. Apply the appropriate voltage and it lights up! It looks a lot like a thin flexible neon tube. They come in many bright colors and can be driven pretty easily...

If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at...

This is a translucent silicon rubber button pad with 16 buttons originally inspired by the folks at monome.org . Each button has a hole underneath that accepts either a 3mm or 5mm standard LED. The idea is that you can create a button...

This a simple breakout board for the button pads. Each LED and button is brought out to the side connectors. The connectors are soldered to the back side of the PCB. We recommend trimming the connector leads on the button side as short...

The SpeakJet is a completely self-contained, single-chip voice and complex sound synthesizer. It uses a mathematical sound algorithm to control an internal five channel sound synthesizer to generate on-the-fly, unlimited vocabulary...
