Nowadays, if you want to ‘check in with Foursquare’ at your local laundromat, deli, or gas station, you need to take out your phone and manually ‘check in with Foursquare’. It’s like we’re living in the stone age. iBeacon, Apple’s NFC competitor that operates over Bluetooth 4.0 changes all that. iBeacon can automatically notify both iOS and Android users of where they are. [Kevin Townsend] over at Adafruit came up with a tutorial that turns a Raspberry Pi into an iBeacon, perfect for telling you that you’re somewhere in the proximity of a Raspberry Pi, and some other cool stuff too.
The iBeacon protocol is actually very simple. Basically, the only thing the iBeacon transmits is a 128-bit company/entity value, and an optional major and minor values (to differentiate between locations and nodes within locations, respectively). After plugging in a Bluetooth 4.0 USB dongle into the Pi, it’s a simple matter of installing BlueZ and entering the iBeacon data.
iBeacon by itself doesn’t really do anything – the heavy lifting of figuring out exactly which Panera Bread or Starbucks you’re in is left to the apps on your phone. If you’re a mobile developer, though, this is a great way to set up a very useful testing rig.
The iBeacon has been all over the interwebs lately. Here’s a riff on the Arduino Pro MIni that adds a BLE module. It can be used to make an iBeacon clone. You can also hack a VTag keyfinder to operate in much the same way.
Remember that post about pulling a QR Code generator into Google Docs? One could argue that the best use of this functionality is to add labels to your parts storage that lead back to the product page for the component. [Thanks Nicholas]
[Michael] wrote in to share his crowd funding campaign. He is a school teacher and wants to publish a detective story that gets kids excited about STEM.
Our own [James Hobson] made the first cut to be [Adam Savage’s] new assistant. He’s the [TheHacksmith] (read our staff page if you don’t believe us) and is the third entry featured in this vignette. Apparently they’ve got something against Canadians because they say he’s ineligible due to his nationality!?
If you’ve ever been confused about the features of different Xbee modules this comparison chart may be of assistance.
A couple of weeks ago we learned about a contest put on by TheControllerProject. [TouchStone936] gets credit for quick, easy, and functional. His solution to making shoulder buttons more accessible includes hot-glue, a golf tee, and a binder clip. Pretty clever!
Wanting a better color of backlight for his eReader, [Vivek Gani] cracked it open and applied Kapton Tape as a gel to soften the hue.
And finally something very silly. If you put a strong enough prop on the front, you can get just about anything to fly. This instance involves a flying pizza box which to us looks particularly un-flight-worthy. [via Gizmodo]
