MBED is a low cost, low barrier to entry ARM based microcontroller development platform. No software, no dongles, no licenses, no ICE. All you need is a USB cable and an internet browser. The C++ development environment is hosted online. To test your firmware you drag and drop the .bin file onto the MBED device and it's installed and ready to go.
In this video I've used MBED to give my Big Mouth Billy Bass (BMBB) a brain transplant. He used to sing and dance along to Bobby McFerrin ("Don't worry be happy") and a cover of the Talking Heads ("Take me to the river"). Pretty entertaining, but what if you could download new audio clips and new movements? What if BMBB could get his new songs and choreography from a microSD card?
MBED provides C++ libraries to interface to all of the microcontroller features (A/D, D/A, timers, digital I/O, PWM, etc.) and made it a snap to write a .wav file player to play the sound and use the PWM outputs to control the motion.
Enjoy the video, and go to http://mbed.org to learn more about MBED.

GWB doesn't enunciate clearly, which made it a little more difficult. But the rich variety of bushisms compensates for that. The organ music is from the intermission of M

lmao! the george bush one is my favorite.. and whats the song with the organ at the end?

@solimatt The GWB one was hard because he speaks quickly and doesn't enunciate clearly. But the rich variety of Bushims out there makes up for that. The music is the intermission song from Monty Python's "Holy Grail" which is where most of the quotes after the "and now for something completely different" break came from.

did you hack this billy bass

@706michaelwilliam Hi, yes, I removed the original PCB and replaced it with my own. Got some wave files and made up the choreography. It reads wave files and the movements from an SD card. mbed is an ARM powered microcontroller development board that made it all possible.
There is a kit coming! I promise! Watch this space...

Unfortunately hackaday stole your credit and gave it to me! Was all over the net before it was corrected. Sorry steve! - Dan R

It's all good. For anyonee who's interested, I did the firmware that plays wave files, and set up the choreography you see in the video clip. Dan is the one who made Billy twitterable. So there's plenty of credit to go around...
