As homage to Nikola Tesla and things that go bump in the night, Rick Crammond created this spooky sound generator that uses a simple crystal radio circuit connected to a PC's sound-in jack, Tesla-inspired plug-in antenna, and DSP software to control the gain and pitch of the circuit to create some great, real-time sound effects! The same radio circuit is a great RF field detector, makes cool sounds from all forms of light, listens to audio ranges, and even receives AM broadcasts. Because what could be spookier, really, than listening to a late-night, syndicated radio show host!
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.
