How to Plug'n'play with Neopixels

Don't you just love those Adafruit Neopixel rings? I have the 12, 24 and the massive 60 pixel rings, and up until now all my sketches have been configurable to run with any of them, with the size statically set at compile time with a line such as#define PIXELS 24So if I change the ring for a differe...

DIY Connected objects for happy connected people

What happens when a creative technologist wants his family to know he’s thinking about them? He creates a project with Arduino Yún! IMissYou is a simple project transforming a picture in a connected object thanks to a capacitive layer made with Bareconductive Paint and inserted behind the photo. The ‘touch’ is detected by the Arduino through the glass of the frame by a spike in the values (with a basic Capsense library), sent to the internet via wi-fi and delivered to a phone with Pushover.

Martin Hollywood, the Arduino user who made  the project, wrote us:

Looking at the photograph of my family that I have on my desk one day, I missed them and wanted to be home. I touched the photo and realised that somewhere between those was the germ of the idea…

I wanted my family to know I was thinking of them, but I didn’t want to create two products; think GoodNight Lamp – I do love that project. In any case, there was no guarantee they would even notice a ‘blinking’ photo frame responding to my signal. Making the Receive a PUSH notification seemed like a no brainer, but the last time I developed for mobile was iOS 1! There are a number of service apps out there: Pusher, Pushingbox but I decided on Pushover. It had a 7 day trial period and good API support (I’ve since bought a license).

Take a look at his blog for more details and if you want to give him some tips to make it a real product.
