DaveWR is correct, a weather station can be tough. But starting with a temp sensor and getting it working, then add a little LCD display, then maybe a wind speed cone with a voltage divider or a series of reed switches, you know, all very basic. Then start heading into the "wild world." My point was, without a defined project - a goal - all you'll be doing is doodling on a piece of scratch paper without a destination. Instead of a weather station, a add-on project to your favorite hobby. Anything. Something to follow from start to finish. :)
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
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 discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
