- Lets get... physiological! in collaboration withHugo Silva BITalino Enthusiast [email protected]
- TODAY, HARDWARE TOOLS ARE AVAILABLE FOR EVERYONE
- http://arduino.cc
- 300k UNITS SOLD PRE DiY HYPE
- http://www.raspberrypi.org/
- 2.0M UNITS SOLD DURING INTHE FIRST 2YEARS
- THESE ENABLE BEAUTIFUL THINGS, SUCH AS
- a turn signal biking jacket http://www.youtube.com/watch?v=ZtNEPkwCfxA
- or back to the future sneakers http://www.youtube.com/watch?v=k_Efr2TaEPo

- or a Ziphius aquatic drone http://www.kickstarter.com/projects/ziphius/ziphius-the-aquatic-drone
- 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 https://www.how.do/guide/bitalino-usb-interfaces
- G. Mathew.Medical Devices Isolation: How Safe is Safe Enough, WiproTechnologies, White Paper. 2002. MAKE SUREYOU ARE DIRECTLY AND INDIRECTLY DECOUPLED FROM A HIGH VOLTAGE SOURCE WHEN USING LOW IMPEDANCE SENSORS
- an auxiliary connectivity block allows you to add RJ22 plugs for cabled sensor connection
- ANY ACCESSORY WITH AVOLTAGE OUTPUT CAN BE USED!
- analog temperature sensor https://www.how.do/guide/bitalino-a-tmp36-sensor
- tilt switch on a digital input https://www.how.do/guide/bitalino-a-tilt-switch

- Accelerometer | Behavioral Analysis
- ambient light sensing or synchronization (e.g. visual evoked potentials)
- visual feedback or video time stamping (e.g. trigger the LED to have a common mark)
- live broadcast from a body
- ARETHE SENSORS COMPATIBLE WITH OTHER SYSTEMS?

- ALLVERY NICE BUT I REALLY WANT A MINIATURIZED DEVICE
- no sweat... just take it Freestyle

- HOW ABOUT ENCLOSURES?
- YOU CAN ALSO GO 3DPRINTING

- Sneak peak on an API
- API instantiation
- BITalino address
- open connection
- set low bat. th.
- get rmware ver.
- start acquisition
- read samples
- trigger dig. out. 3
- stop acquisition
- close connection
- acquired data
- Enough talk... time to see BITalino in action!
- Were looking forward to welcome you to the in collaboration withHugo Silva BITalino Enthusiast [email protected] family
