LED Gumball Machine

Gyroscopes measure the speed of rotation around an axis and are an essential part in determines ones orientation in space.

We can see electricity in action on our computers, lighting our houses, as lightning strikes in thunderstorms, but what is it? This is not an easy question, but this tutorial will shed some light on it!

Picking up where we left off in "Getting Started with LTSpice," we delve a little deeper into LTSpice through an introduction of Operational Amplifiers (OpAmps).

The What, How, Why, and When of Field Programmable Gate Arrays, aka FPGAs

Review, teardown, and hacking tutorial for the MindWave Mobile, a $99 commercial grade EEG sensor.

Drum machines and keyboards have been the standard for making digital music, but how do you make electronic music if you're trained to play the trombone? One of our Hackers in Residence, Carlos Mello, took it upon himself to find a solution to that very question.

It's now easier than ever to measure and characterize how different materials absorb and reflect different wavelengths of light. The AS726X spectral sensors allow you to detect wavelengths in the visible range (VIS) and near infrared range (NIR)!

In this tutorial, we will learn about how to create an interactive theatrical prop for a performance by 3D printing a translucent diamond prop using a non-addressable RGB LED strip and AT42QT1011 capacitive touch sensing.
