The Electric Imp looks very interesting. A device that’s the same size and shape as an SD card, but is in fact a WiFi interface. There also seems to be a development board in development that already contains a temp sensor and photocell amongst other things.
It’s been set up by ex-Apple and Google people, with the aim of making ‘the internet of things’ more easy to configure. You teach the device the SSID and passphrase for your WiFi network by placing it on the screen of your Android or iOS phone, which then flashes the screen to transfer the data over. Sounds much more straightforward than setting up the WiFly RN-XV!
There might be a possible downside in that it runs all the software management and data handling in the cloud (although the ‘sketch’ or program runs on the device itself). So I’d have questions about reliability and the security of my WiFi network password.
But I’m pretty intrigued, I might have to get one and have a little play. Cool Components are selling it for £19.90 (as at October 2012)
