Controlling data and power lines independently with HubTool applicationNotice that when the power line is enabled, the Android device indicates it as "charged". After enabling the data lines, the device then indicates that it enumerates as a media device from the USB Hub. Doing…

Setting up product manufacturing involves many complicated systems and processes. In order to produce millions of devices a month, companies need to massively scale these systems. Yet this scale is in direct conflict with fast product changes and time-to-market for "the next big thing". Major…

INTRODUCTIONThe Sharp family of infrared range finders are used extensively for robotics and automatic distance measurement applications. Unfortunately, the output of these sensors are inherently non-linear. In other words, a big change in output voltage does not always indicate a big change in…

The most popular infrared detectors and rangers are designed and manufactured by Sharp. Boasting a small package, low-power consumption, and a variety of output options, Sharp Infrared Detectors and Rangers are built for any application that requires accurate distance measurements. Creators…

INTRODUCTIONElectromotive force (EMF) refers to the voltage generated by a spinning motor. Measuring this voltage in order to determine the rotational speed of a motor is commonly called Back-EMF since the voltage tends to "push-back" against the circuit driving current into a motor's windings.…
