Build a DIY Thermocam | Make:
The basic idea of my low-cost thermal imager started with my physics class in 2010. Our teacher bought a single-point infrared thermometer, also called a pyrometer, and asked if anyone wanted to use it for a science competition later that year. A friend and I came up with the idea of creating a thermal image scanner using servomotors to move the infrared sensor over a large area.

FFT: Fun with Fourier Transforms | Adafruit Learning System
Have you ever wanted to build devices that react to audio, but have been unsure about or even intimidated by analyzing signals? Don't worry! This guide is an overview of applying the Fourier transform, a fundamental tool for signal processing, to analyze signals like audio. I'll show you how I built an audio spectrum analyzer, detected a sequence of tones, and even attempted to detect a cat purr--all with a simple microcontroller, microphone, and some knowledge of the Fourier transform. Continue on to learn some background information about the Fourier transform.

Retractable Console Allows Wheelchair User to Get up Close and Personal @ Hackaday
[Rhonda] has multiple sclerosis (MS), a disease that limits her ability to walk and use her arms. Her chair comes with a control console that swings out of the way to allow her to come up close to tables and counters, but she has problems applying enough force to manually position it. The Boston Home has a fully equipped shop to extend and enhance residents’ wheelchairs, and they got together with students from MIT’s Principles and Practices of Assistive Technology (PPAT) course to hack a solution.
