My wireless temperature probes work by using an Xbee module to transmit readings from a TMP36 down to the Arduino base station. The XBees aren’t too cheap, coming in around £19 or $23 so I tried to be cheap and ordered mine from Sparkfun, I bought this XBee (series 1) with Chip Antenna and these breakout boards. I […]

Tweet-a-watt – How to make a twittering power meter… This project documents my adventures in learning how to wire up my home for wireless power monitoring. I live in a rented apartment so I don’t have hacking-access to a meter or breaker panel. Since I’m still very interested in measuring my power usage on a

My Motivation This winter my girlfriend had a lot of trouble waking up in the morning and seemed to be suffering from SAD (Seasonal Affective Disorder). I even notice how much harder it is to wake up in the winter since the sun hasn’t come up yet. Symptoms of severe SAD can include irritability, oversleeping

Introduction An excerpt from OmniGlot.com about the origin of Morse Code: Morse Code was invented by Samuel F. B. Morse (1791-1872), a painter and founder of the National Academy of Design. He conceived the basic idea of an electromagnetic telegraph in 1832, and produced the first working telegraph set in 1836. This made transmission possible
