This project is a mixer, especially designed for electronic musical instruments.  It has 16 inputs, each with a level control and a three-way switch which selects between two subgroups and mute.  It has a very clean signal path, and sounds amazing!  =]

We now have this sensor, which was originally built for monitoring the awful climate control at my office, set up monitoring MakerSpace instead. The project is a very simple bridge between an inexpensive combined temperature and humidity sensor chip and a computer. The idea is to take frequent measurements of the temperature and humidity in the room and use them to produce graphs.
