Do-it-yourself (DiY) hardware platforms have spun a true global revolution in the way in which the digital interfaces with the physical. From twitter-controlled christmas trees to bicycle jackets with turn signal lights, the DiY movement is driving endless innovations and stimulating an age of creative engineering. Body signals have been largely neglected within this revolution, but now a newcomer is extending the principles of physical computing to the domain of body signals, forever changing the way projects and applications involving physiological data are made. In this talk we'll look into BITalino, the only purpose-built toolkit in the world that allows anyone to create cool projects and applications with body signals. http://arduinoday2014atiscte.wordpress.com/events/arduino-day-2014/speaker/hugo-placido-da-silva/

BUT WHAT ABOUT BODY SIGNALS?
the only DiY kit in the world for biosignals...
and imagination is really the limit!
although its also thought for versatility
theres free software to go with it as well
a growing number of programming APIs
BITalino... currently provided as a low-cost toolkit
real-time sampling and conversion of the analog sensor outputs
to a digital representation
CAN WE UPLOAD OUR OWN CODE?
yes, but may be easier to use an Arduino
HOW ABOUT STANDALONE APPLICATIONS?
needs a 3rd party system via UART or peripherals
3.3V and 1.65V regulated power supply, with battery charger and
voltage information
WHAT IS THE BATTERY LIFE?
~10h with included battery
interchangeable Bluetooth communication interface with 115.2k
bps transfer rate
WHAT OTHER INTERFACES CANYOU USE?
any UART-compatible adapter or device

IMPEDANCE SENSORS
an auxiliary connectivity block allows you to add RJ22 plugs
for cabled sensor connection
ANY ACCESSORY WITH AVOLTAGE OUTPUT CAN BE USED!
