Arduino Screen Controller for Raspberry Pi Part 3 Hardware Final

Sunday, April 28th, 2013

A few months ago I setup a web browser based dashboard running on a Raspberry Pi, displaying weather, time and transit information.  It worked out well, but it’s success revealed another problem.  Turning the screen on and off multiple times a day was getting old.

So I did what any technically inclined person would do.  I decided to create a device to turn the screen on and off by responding to dramatic changes in ambient light.  The device would also provide a manual power toggle and button to refresh the browser.

This is part 3 of 3 describing the final hardware that was built from the prototype.

Although intended to be used with a Raspberry Pi, the screen controller can be used to emulate a USB keyboard and send any desired keystrokes.

Raspberry Pi Install

Saturday, March 2nd, 2013

I recently picked up a Raspberry Pi from Creatron Inc with the intention of creating a dashboard.

The following are instructions for installing Linux (Debian Wheezy) on the SD card from OS X Mountain Lion.  I used the built in SD card reader on my Macbook Air and used several different SD cards, all 4 Gig or greater and all class 10.

These instructions assume comfort with the command line.
