Sleep Apnea effects 5-10% of middle aged men (half that for women). It is surprising just how few DIY projects are getting passed the basics of monitoring for movement. Marc Merlin has shown a tenacious dedication to building his own DIY rig. Marc ended up cobbling together a solution using an accelerometer, resistive fabric chest strap and a Zeo for EEG sleep monitoring. He pushes all the data through an Arduino to a Linux box using Xbee. The most helpful part about Marc’s project is what did not work. He tried a lot of different sensors and off the shelf products but had to dump them due to proprietary communication issues or low quality data.
