I'm interested in computer graphics, algorithms, combinatorics, mathematics, and meta programming. My favorite languages are Prolog, C++, OCaml. I like to make cross-platform graphics applications.

comment Sound level meter for a given range of frequencies
So if I understand correctly, will a FFT allow me to separate the frequencies even if they have been recorded together? As you can see, I don't have any knowledge in signal processing, and I don't know the exact nature of sound.

About the additional hardware: on another project using the same sensor, the person who designed the project used a sigma delta ADC to read the sensor on a Raspberry Pi. How does that compare to your solution with an OpAmp ?

Before going any further I don't really understand this graph; why is time involved in the reading of a concentration ? Any pointer would be appreciated.

comment How can I measure the charge of a rechargeable cell?
Thanks for all your advices. I think that the problem what not related to the batteries, and I know now how to test them (see other answers). It was related to the USB hub which is currently under heavy load. I cannot unplug the drives which are connected to this hub right now, so I'm still not 100% sure. The red light seemed to indicate a lack of link connection from the dongle. Unfortunately the Macbook Pro I'm using has only 2 USB ports.
