Saelig Company Inc.'s USB DrDAQ is a combination scope/data-logger/IO board with 15 I/O
channels. Software provided with the unit provides 100kHz-bandwidth
oscilloscope and datalogger, with extra input and output capabilities straight
out of the box. Built
into the USB DrDAQ are a microphone, light sensor, RGB LED, oscilloscope and
resistance inputs, 4 digital I/O ports, 3 sensor ports, a pH/redox sensor input
and a signal generator output. The unit is powered from the USB port so there
is no need for an external power supply. USB DrDAQ samples at 1MSa/s and can be
used as a single-channel 8-bit 100kHz oscilloscope or spectrum analyzer with
the ability to measure voltages up to Â±10V.
USB DrDAQ's 10-bit D/A output
features a 10-bit signal generator - a standard function generator, but also an
arbitrary waveform generator (AWG), so customized waveforms can be created. An
RGB LED can be used to display any color for a variety of indicator purposes.
Two of the I/O ports can be used as pulse counting inputs, or PWM (pulse-width
modulation) outputs. The sensor ports can be used with a range of temperature,
humidity and oxygen sensors, or with custom sensors built by the user.
USB DrDAQ will find its way into
a wide variety of applications from education to research for signals at audio
frequencies and beyond. It is supplied with a free Windows Software Development
Kit (SDK) with fully documented function calls to control all aspects of the
device, so it can be integrated into other programs in C, C++, Microsoft Excel
and National Instruments LabVIEW.
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.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
