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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
