It's very pretty they put everything into the shell of the bulb. My smart bulb is a regular led lamp that I've run the power through a nice transistor and arduino sitting next to the lamp on my desk. However I have a nice webapp and even a brightness sensor to adapt to light in the room.<p>Some videos of my lamp: <a href="http://fluffyelephant.com/2012/09/two-videos-about-my-led-lamp/" rel="nofollow">http://fluffyelephant.com/2012/09/two-videos-about-my-led-la...</a><p>And a write-up: <a href="http://fluffyelephant.com/2012/05/lamp-update/" rel="nofollow">http://fluffyelephant.com/2012/05/lamp-update/</a>
Is the Arduino really necessary here? From the description, it appears to be basically equivalent to 3 wires between the Bluetooth module running the actual control code and the transistors switching the LEDs. (Honestly, Arduinos seem to be a bit overused in general...)
Neat shortcut -- instead of building your own main-to-5v power converter, you found the best one made by someone else and just used it.<p>Edit: I just realized you're basically some code away from reinventing LIFX.

Stuffing the iphone power supply into the lightbulb is interesting. I'm sure if you took the time you could make/find a smaller switching power supply to stuff in there, but using a well-designed, readily available power supply in this kind of project is resourceful. I wouldn't have thought of it.
