Rosalind W. Picard put together a fascinating backstory for a device that can predict seizures in 2012. Her MIT project is of just as much interest today for several reasons. The first being that it is a fun write up with a real human story. It begins with a a non-verbal autistic boy who had a grand mal seizure while wearing a galvanic skin sensor. The second point of interest is that galvanic skin sensors (GSRs) are easy to make and use and could be utilized in many types of DIY biohacking projects from lie detectors to seizure detection.
As I sat in my office, reviewing the past week’s data, I thought, “This day looks pretty typical” and “Normal variation here.” Both wrists transmitted signals that went up with mild autonomic stressors, and down with relaxation. Usually the two sides of the body respond with similar signals, and this was the case in the days I had just viewed. Then I clicked to see the next day’s data. My jaw dropped. One wrist showed a peak that was greater than ten times the typical stress response. The other wrist showed no response at all.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
