Arduino based biofeedback unit

[Michael Gerstenmayer] has been very successful in developing a biofeedback system. He’s based the build around an Arduino and started adding different chunks to the project to develop a full-featured unit. It can take your temperature (with an IR sensor…. not the hard way), measure your galvanic skin response (conductance), and produce feedback based on this data. Interestingly enough, he built a peripheral vision feedback system based on the glasses frames seen above. They have an LED on each side which are illuminated based on the sensor data.

By using the Arduino’s USB connection the data can also be processed by a PC. [Michael] spent some time working with an open source program called BrainBay to gather and map the stream from the sensors.

We enjoyed reading about the build, but there’s no information about what he’s got planned for this project. That shouldn’t stop you from setting up your own rig and using it as a lie detector, or for the devilish purposes we’ve seen in the past.

Headpiece Jabbing for Smiles


[Lauren] has created a facial conditioning device dubbed the Happiness Hat. The hat measures a sensor at the wearer’s cheek to determine if the wearer is smiling. When the hat does detects the wearer is not smiling, it activates a servo that prods the wearer. This project is fairly unique in that it provides haptic bio-feedback of what the body is doing, a similar project to the Happillow. While the Happiness Hat seems to work for treating the outward symptoms of unhappiness, this is but an early step towards the droud.
