From the project

A 0.01Hz-1+MHz low noise amplifier

Current Status -------------- I have made two of these and have done a fair amount of testing to nail down root causes of some of the issues (see later in this readme) that have proven to be a bit of a nuisance. I am also moving things around a bit on the battery and battery charger boards to allow a board-to-board connection of the two and increase the clearance between the battery board and the amplifier board. I have also tested improvements to the input stage that significantly reduce the low frequency noise, lowering the 1/f corner to <1 Hz. These are detailed in the issues section #7.
