Bluetooth Low Energy Beacons in a Flock of Birds

birds_ready

No, not real birds! [Kyle] works in operations at a web company and needed a way to send alerts to his fellow coworkers, so he modified a flock of Audubon Society plush birds to respond to a Bluetooth beacon.

Using NRF24L01+ Bluetooth Low Energy modules, [Kyle] installed one each in these battery-powered singing birds. The devices are presumably powered off of the battery that comes with the birds, but the use of the BTLE module means the batteries won’t discharge as rapidly.

[Kyle] also built an API that works over HTTP or IRC, which means that the employees in the office can activate everyone else’s birds over a simple and intuitive interface. The birds can be activated one at a time, or all together in “panic” mode as one giant flock (in case of an emergency in the office). They can also be activated one at a time on a specific hour to simulate the Audubon Society’s bird call clock.

He calls the device equail and it’s a very unique notification system with a lot of applications. All of [Kyle]‘s code and documentation of his project are available on his github site. He also used this primer on BTLE to get started, and this guide on sending data over BTLE to help get the project in the air.
