KeyChain Helper

thingiverse

I conceptualized a keychain attachment that seamlessly integrates a Bluetooth module and a microcontroller to effortlessly connect with your personal phone via a simple button press. This sends an immediate message or call to your designated guardian, providing peace of mind in emergency situations. This small, discreet design is easy to access and convenient, as 90% of people typically keep it within arm's reach in their pocket. It requires minimal changes to daily routines, making it an effective safety measure that's always ready when needed. The bottle opener mechanism remains at the ready for a refreshing drink whenever desired. With ample space left for a compact battery and micro USB charging port or easy battery replacement, this keychain attachment can be a trusted companion in daily life - even when you forget your house keys inside.
