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!
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
