KeyChain Helper

I designed this keychain attachment with a bluetooth module and a microntroller with the idea of connecting it to your personal phone and with a botton, a message would be sent via bluetooth connecting immediately to the desired guardian via message/call/etc.

Would be something small, easy access and, i would beleive, 90% of people of it in pocket, not changing nor implementing nothing else in your daily rotine but implementing a small reassurance for safety or emergencies needed. With the mechanism for a bottle openner allways beeing preapred for a drink. :D

Still having some space for a small battery and a micro USB entry for charging/or an eazy way to change battery, this item could be very well used in any day if you dont forget your home keys inside the house. :P
