I’ve been pretty busy lately working on the latest spectrum analyzer V2.1. Its available in the online shop if you are interested in getting one. Here are some videos bellow with the new blue LED’s and with a half green/half red display.

I have also been working on the new expansion board pictured bellow. The Expansion Board was created to help you create bigger custom displays for the Spectrum Analyzer. The Expansion Board works by switching the signals from the spectrum analyzer with the help of high current MOSFET transistors thus giving you the possibility to output higher voltages and currents for your custom setup. You can read more about it on the forum.

There is also a new assembly guide for the audio spectrum analyzer V2.1 that will be helpful to those that get the kit unassembled.
