#DementiaHack - Facebook sponsored hackathon


#DementiaHack - Facebook sponsored hackathon

Toronto, Canada

November 2015 - November 2015

In a span of 36 hours at a Facebook managed hackathon #DementiaHack ( , built a system that will immensely help dementia patients and their caregivers.

The system has 3 components:

- IoT: built the board with sensors and hooked it up to an electric imp (+ programming its board and agent using Squirrel language)
- Cloud (AWS) : the board sends messages/notifications to the cloud (node server)
- Node.JS server running on the cloud
- The node server receives a request and pushes notifications to phones using GCM (google cloud messaging platform) and ionic push notifications.
- Mobile app using Ionic

The details of this system will be displayed as soon as I finalize a small webpage for it. For now check

Are you an investor/philanthropist? this system is extremely useful and got a lot of great feedback from hardcore medical professionals who asked me to pursue it. I didn't share all details of what it does and all its components, will keep that for when we meet.

To be able to make it available to dementia patients /caregivers I'd need some funding to order and build the microchips components so that they are ready for distribution.
