Tonight I started proto typing a thermometer idea. The objective is to create a remote monitoring device that can be placed indoors and outdoors. Possibly adapted for other uses as well. Maybe monitor the temperature of the fridge or the HVAC, or spa. I can go on... and on...

Here is the first stage of my proto typing. It is a simple circuit that entails an arduino, a LCD display and a DS1620 thermometer IC.

I plan on using an XBee to create the remote connection between the Thermometer circuit and Display circuit.

Radiometer

This afternoon, I watched "An Inconvenient Truth" It inspired me to take a short video of the Radiometer I have.
