Electrochemical sound synthesizer

While not conventionally musical, the Electrochemical Synthesizer’s process for generating sound is unusually interesting – Pressing a key causes salt solution to flow over a copper and aluminium connection generating a low signal which is filtered by a capacitor and then amplified, creating a complex white noise, with amazing fluctuating oscillations. The device demonstrates how […]

Littlebits prototyping

A demonstration of the littleBits electronic component system in use prototyping some features for a coffee maker design. littleBits is an opensource library of discrete electronic components pre-assembled in tiny circuit boards. Just as Legos allow you to create complex structures with very little engineering knowledge, littleBits are simple, intuitive, space-sensitive blocks that make prototyping […]

Ard-e: Wall-E V. 0.001?

Ard-e: Wall-E V. 0.001?

An Arduino, model bulldozer, servos, and sensors can be hacked together to make a sub-$100 robotics platform, appropriately named Ard-e. While certainly nowhere near as fancy as this Wall-E replica, the price is right and the Arduino’s got a huge body of pre-existing code for working with sensors that the aspiring roboticist can build upon.
