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. In […]

Nickjohnson posted an update to his network analyzer we covered previously: More tweaks and improvements! I’ve moved to a dedicated LED dimming controller for the backlight instead of resistors, and made a few other layout tweaks. It’s now out for fab. A friend put together some nice renders of the case for me Via the […]
