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.
At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
