// Output sine wave with frequency sweep between 100Hz and 10kHz (32 samples) on analog pin A0 using the DAC and DMAC
// Generously initially donated by MartinL2
// Written for M0.  Tested on Adafruit Feather M0 with ATWINC-1500 WiFi
//
// BDL change to 100Hz to 25000Hz
// BDL change to sweep in frequency, rather than period.  This makes it look better on an FFT
// BDL change to have constant power in FFT bins.  Each frequency operates for the same amount of time yielding constant 
// power in the FFT

We are a small collective aiming to connect grassroots movements with academia and everyone who is looking for an alternative way of living. To achieve this goal, we arebegninng by conducting interviews with activists, open and libre innovative organizations ... and anyone with ideas on how to create a better world.

In the future we would like to conduct research motivated intrinsically, following our values to solve problems and without pressure to publish as much as possible -- research of high quality, but pursued without being driven by academic reputation or particular sources of funding. We dream of establishing an institute which is non-hierarchical, open-minded, and focused on peer-learning.

In addition to interviews and research projects, we would also like to focus on teaching and dissemintation -- through workshops, as well as through an online magazine. Our concept for such a magazine invovles short reviews, news, and interviews, as well as longer-form reports and analyses on topics we would li
