This blog has moved to http://BB-8.blogspot.com. A full size Lego BB-8 is nice and cool, but wouldn't it be better if he acted like BB-8?
The first step to doing that would be to get him to talk! So here goes! Looks way better with some animated LEDs!
Yea, I know he needs the newer sounds, but the movie just came out you know?
His "voice" is a Windows Phone connected with a Y cable to a portable Bluetooth speaker and the microcontroller that does the LED levels. The LEDs are little RGB chips that can be individually programmed.
I had to shave the front brick a little to get it thin enough to light up well, but I think it looks pretty good. (Before shaving it was just a little yellow dot. Interesting that the brick turned the light yellow).
