For a couple years now, I have been looking at home weather stations to measure wind speed and direction along with the other usual stuff - indoor and outdoor temparature, humidity and rainfall. I went with a WMR968 Professional Weather Station from Oregon Scientific. It uses solar to power wireless transmitters to send the data from instruments to the display. It was a bear to install, taking 6-8 hours to get the anemometer high enough and away from obstructions. The directions were so bad, I thought it would never work, but it does and fairly reliably - for now.
But I wished I had waited for the anemometer from Fascinating Electronics. It’s a homemade but cleverly fashioned together with PVC pipe. The anemometer (weather vane and cup rotor) is $100. Throw in another $25 for the temparature/humidity sensor and you all but the rain guage you get in the WMR968 which goes for $250 (I wanted Davis Vantage Pro 2, but could not justify the $500+ cost). To be fair, Fascinating’s piecemeal approach isn’t for everyone. It does not come with an electronic display so you have to build or acquire your own or use a calibration chart to translate pulses from the anemometer in MPH. But that could be a fun project.
According to a study by the National Institute of Standards and Technology, one of the factors in the collapse of the original World Trade Center towers on Sept. 11, 2001, was the reduction in the yield strength of the steel reinforcement as a result of the high temperatures of the fire and the loss of thermal insulation.
Robots are getting more agile and automation systems are becoming more complex. Yet the most impressive development in robotics and automation is increased intelligence. Machines in automation are increasingly able to analyze huge amounts of data. They are often able to see, speak, even imitate patterns of human thinking. Researchers at European Automation
call this deep learning.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
