Simple scalar network analyzer

rheslip blogged about his simple scalar network analyzer project: The principle is to stimulate an electrical network with a sinewave and measure the magnitude of the response. If we sweep over a range of frequencies and measure the power transmitted through the network we can determine its frequency response.  Transfer from the input port (1) […]

LED cube spectrum analyzer project

John Boxall over at Tronixstuff posted a step by step guide on building a LED cube spectrum analyzer: A few weeks ago I was asked about creating a musical-effect display with an RGB LED cube kit from our friends over at Freetronics, and with a little work this was certainly possible using the MSGEQ7 spectrum analyzer IC.
