Android ADK and mbed.org

The 'mbed kit' just landed on my doorstep, sent courtesy of the good guys at ARM (Cambridge, UK).
This gadget supports the Android ADK (http://mbed.org/cookbook/mbed-with-Android-ADK)
which is fully documented here and, to have an idea of the geeky-fun that can be had with these gizmos, I suggest you check out this video.
I fear that my weekends are likely gone for quite a while now....

Just as an example of what is possible, the following snippet will make the LEDs flash, as well as connect to a terminal on the host PC to use as stdout; this is a very basic adaption of the HelloWorld.cpp app, and some tutorials from mbed.org: the point being that it took me less than 30min to get going!

#include "mbed.h"

// USB out to the host PC - from a terminal window access
// using: screen /dev/ttyACM0
Serial pc(USBTX, USBRX); // tx, rx

// Board LEDs
DigitalOut myled(LED1);
DigitalOut yourled(LED2);

bool on = true;
void quit() {
  on = false;

void toggle(DigitalOut d1, DigitalOut d2) {
  d1 = !d1;
  d2 = !d2;

int main() {
  pc.printf("Starting LED flashing...\r\n");
  Timeout to;
  myled = !(yourled = 1);
  to.attach(&quit, 5);
  while(on) {
    toggle(myled, yourled);
  myled = yourled = 0;
  pc.printf("Exiting now\r\n");

And this is what came out of it:
