iPad Mini

Every try playing a guitar that's out of tune? It doesn't sound pretty. Even a great guitarist can't do much with an out-of-tune guitar. Everyone knows that guitars need to be tuned but did you know that your Wi-Fi can be optimized? Did you know that optimizing your Wi-Fi will translate into faster...

This picture shows a conducted measurement test setup using iPad Mini and WiPry-Combo . The extension cord between iPad Mini and WiPry-Combo affords users much needed flexibility in positioning the DUT with respect to the measurement instruments. In this case, the iPad Mini can be placed in a safe...

The figure above contains a series of charts showing the equivalent DC voltage from a Pulse Width Modulation (PWM) signal over a period of time. There are subcharts showing the measured PWM signal at points in time indicated in the main chart’s saw tooth shaped waveform. I created these charts from...

The figure above is a schematic diagram of a Pulse Width Modulation (PWM) signal driving an LED with an handheld oscilloscope and voltmeter monitoring the LED’s voltage. In this post and the next we will look at how the pulsed voltage resembles a DC voltage to a load, and use an Excel spreadsheet,...

In the picture above, Oscium’s iMSO-104 and an iPad mini display the pulsed output of an Arduino board’s Pulse Width Modulation (PWM) output. In the foreground, an LED is illuminated by the pulses from the Arduino board. Making an LED light up is a simple use for this circuit, but often it’s also...
