I've been building the earlier prototypes by hand, and in conjunction with the Femtoduino boards, I've hand built about 2,000 boards to date. (Parts are smaller than poppy seeds)
I simply could not keep staying awake till 6am every day to ship stuff out fast enough, ...so I've launched this Kickstarter to get IMUduino fabricated locally, and shipped quickly.
If you want to build Drones, map stuff without GPS, build Smart Home devices, or wearable...using PhoneGap and Arduino, then I invite you to have a look. I've added sample code as well.
