IoT: Real time control of stepper motor with web browser

This is the first version of the marble dispenser for the marblerun we are building.  

The stepper motor is controlled from a web browser in real time. Using web socket to connect the web browser with a server running nodeJS and an netduino that connects to the server using a simple tcp connection. When you move the slider on one client it is moved on all connected browsers/devices and the stepper in sync.

We are using on the nodeJS server to handle the connection, so it will work on browsers that not supports sockets. It is really impressive how little code is needed to get everything upp and running.

Find home detector - LilyPad Arduino

The Find home detector is a device to show me the way home by indicating the direction with a light. It uses a LilyPad, GPS, compass and some LEDs. Using the GPS to get a position and then calculate the direction to the location of my home. The compass is then used to get my heading so it is possible to indicate the direction I should travel.

First sketch of the Find home detector

Work in progress
