This is a mini project showing how to build a small device helping you to find your lost keys. It’s working with Bluetooth low energy modules and utilizing ATiny MCU power saving capabilities. It can be also controlled from the mobile phone. I will give you an update as soon I get a Android 4.3+ phone.

London’s Gatwick Airport now has 2,000 beacons for in-house navigation
Sophisticated in-house environments for example, airports and department shops is usually a nightmare to find your way around. And although Google is eyeing phones with 3D detectors as one prospective solution for places GPS won’t correctly reach, another approach is to kit out an interior with many Bluetooth beacons – giving smartphone users located-locked pings to fix onto to recognise exactly where they’re.
The UK’s second busiest air-port, Gatwick airport, has chosen the second way to power an indoor navigation system it’s launching as a part of a broader, multi-year transformation program.
It’s finally finished kitting out its two terminals with close to 2,000 battery-powered beacons in order that digital map users will get a more precise blue dot as they go around. The beacon system will also be employed to power an augmented reality wayfinding tool – to make sure mobile users will have the ability to be guided to specific locations inside the terminals thru on-screen arrows. The beacon system is scheduled as supporting positioning with +/-3m precision.
Gatwick is planning to integrate indoor positioning into some of its apps, and says it’s in discussions with airlines to tap into it for their own apps and services – giving example of them having the ability to send push notifications to remind individuals if they’re running late, or even consider whether or not to wait or offload luggage so an airplane can take off promptly.
Stores and other third parties will also be able to utilize the system for proximity detection of potential clients and push advertising messages – at least to those who’ve opted in to receive them.
Gatwick says it won’t be obtaining any private information through the beacons but says “generic information on ‘people densities’ in different beacon zones” will be employed to help to improve airport operations – such as queue measurement, streamlining passenger flows and minimizing over-crowding.
The airport has worked with UK new venture Pointr on the system. In addition to developing software and managing the system on an ongoing basis, Pointr provides an SDK with support for 3D AR wayfinding to enable third parties to take advantage of the functionality.
