Using the Adafruit motor shield to power chunky motors. If you don't get enough grunt from the motor *do not just run 2A through it*. Smoking occurs. see: http://learn.adafruit.com/adafruit-motor-shield
#include <AFMotor.h>
/*
Graccefully spin up, run, spin down and reverse a motor
*/
AF_DCMotor motor(2, MOTOR12_64KHZ); // create motor #2, 64KHz pwm
// FORWARD = 1, BACKEWARD = 2, RELEASE = 4
const int UP = 1;

Notes on tracking ships. IN THE FUTURE.

How I'd build an awesome thing, if I were me, today.

  • Realtimey push of async events to all clients - We track ships. Ships move. The client should be informed of each position report, as they happen. I strongly believe that this should be at the core of all our apps. This expands to a generic async event notification system. Consider WebSockets via Engine IO or push as a service via http://pusher.com
  • DOM templates. This isn't just a bunch of strings dammit, it's chunks of HTML. The templates should be HTML too.
  • Client side DB. Structured APIs over localStorage & indexDB are sufficiently advanced that we can sync subsets of the server data with a client side DB-like structure. User interactions manipulate the local data, and just those diffs are communicated to the server. If the client maliciously force-violates the front-end validators, then the server simply rejects the change, and sends back the relevant diff to patch their database state

Only allow users on a given email domain to log in to your meteor app.
/*
Only allow users with a verified email address on a pre-verified domain to log in.
We're getting people to authenticate and only authorising those that have an email we recognise.
Assumes a Meteor.settings like:
{ adminDomains: ['tableflip.io', 'meteor.com'] }
...and meteor-developer accounts, but other login mechanisms (email, twitter) would work too.
