This board is made for microstepping for stepper motors. It can attach directly to the controller's 96-pin DIN connector, with no cables required, and Galil's SDM-20620 works well with 2-axis applications. The SDM-20640 measures 6.92 × 5.10 inches. It includes four microstepping drives on one board, each capable of driving a two-phase bipolar stepper motor running at 18V dc to 60V dc at up to 3.5 Amps. They also put out 64 microsteps per full step or 256 steps per full cycle, for 12,800 steps per revolution for a standard 200-step motor, with a maximum step rate generated by the controller of 3 million microsteps/second.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
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.
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.
