We first met Hugo Silva last year when he introduced us to Bitalino, an Arduino-compatible electronics toolkit designed for exploring the various physiological signals that the human body gives off. The latest iteration of the platform, BITalino (r)evolution, is more affordable and capable than ever, but the team still needs backers to get off the ground. From their Kickstarter:

Body signals have hundreds of applications; assistive technologies for people with disabilities, biofeedback for stroke and muscle disorders rehabilitation, or self-management of psychological disorders (e.g. anxiety, depression, PTSD, ADHD) are just a few examples. Still, BITalino is an unique DiY toolkit, which can be used by virtually anyone interested in creating projects ranging from muscle activated air drones to heart-rate monitoring bicycle handlebars, smart / enchanted objects, interactive installations, or affordable medical devices and personal diagnostics apps.

By supporting our Kickstarter campaign, you can potentially be contributing to revolutionise healthcare and biomedical engineering around the world. BITalino has grown to become the platform of choice for hundreds of people worldwide already, but it wasn’t designed with financial profits in mind, hence the reason we need your help now.

If exploring biosignals sounds interesting to you, there’s still an early-bird deal for your choice of application-specific sensor kits for $79 with a projected shipping date of May 2015. These application-specific kits come in variants for sensing heart rate, muscle activity, arousal, and motion. Of course, they also offer kits that include sensors for all of the above.
