OpenEnergyMonitor – Documentation finished for the whole home energy monitor

Tuesday, February 16th, 2010

Over the Top:
The project Top: The display, Middle: The main unit with CT sensor, Voltage sensing, USB datalogging… Bottom: Ethernet unit for internet connectivity, Very Bottom: graphs

The energy monitor is working away logging energy consumption data, giving some informative readouts and nice looking graphs! there’s more about it in the blog post here and the documentation here.

Microprinter RSS Arduino Driven

Monday, February 15th, 2010

Nice step by step project to display feeds on a microprinter.

The concept of Microprinting as described by Tom Taylor is “an experiment in physical activity streams and notification, using a repurposed receipt printer connected to the web”. Using this and the works of others as inspiration, I set about making my own Internet connected printer.

Before starting the project, I hadn’t had any previous experience of building electronic circuits, and it had been over 10 years since I had last picked up a soldering iron. Unperturbed, I set out and acquired everything I needed for the project:

The serial output of the Arduino board isn’t natively compatible with the printer – you need to run the signal through the MAX233 chip to transform the output to the correct voltage.

Don't walk! Controlling a pedestrian sign with an Arduino

Tuesday, February 9th, 2010

From Ben Shiriff: My latest project is controlling a pedestrian sign with an Arduino, so it will automatically step through the states of walk, flashing don’t walk, and solid don’t walk. In addition, I added infrared remote control support so I can use a remote control to turn the sign on and off, set it to a particular state, or start the cycle.
