OscilloPhone: Use your Smartphone as an Oscilloscope / Signal Generator

Smartphone as an Oscilloscope

Oscilloscopes and Signal Generators are two essential electronics devices to create and test electronic circuits. Unfortunately, these devices are very expensives for students starting electronics, or makers who want use electronic circuits in their creations just once…

The idea of my project is to rethink your smartphone as a portable, powerful and secured platform, able to simulate an oscilloscope and a signal generator for your electronic circuits. Here, your phone isn’t just an accessorize or an ordinairy remote control : it becomes the center of the project, and a tool to help you create better things in the future.

The OscilloPhone project includes:

• an oscilloscope input for visualize electronic signals ranging from 150 Hz to 15kHz. Beyond this bandwidth, the displayed signals have a lower quality. Signals up to ±50V up can be injected on the input of the circuit. A warning LED alerts the user when a too high signal is measured.

• a signal generator output, able to generate sinusoidal, square and triangular signals up to 15kHz. A potentiometer is used to adjust the signal amplitude.

• a signal generator power output, able to generate sinusoidal, square and triangular signals up to 15kHz and 2A. A potentiometer is used to adjust the signal amplitude.
