Husker Scope

Senior Design Project - Husker Scope

The Husker Scope project is an all-in-one cross platform (iOS, Android, and Web App) application that implements a Dual Channel (DC) Function Generator, DC AM/FM Modulator, DC Oscilloscope, DC Spectrum Analyzer, and an 8-channel Logic Analyzer. This app outputs audio range (20Hz to 20kHz) signals via the speakers / 3.5mm audio jack left & right channels and inputs signals either through the microphone audio jack (for audio input ranges) or through a custom hardware board (that can handle up to 500kHz signals). The hardware board can connect through serial on a PC or through Bluetooth on a mobile device. This app has been available for engineers and scientists around the world since April 2022.

Husker Scope Interface Hardware

In order to get the mobile and web apps to allow an external microphone input we had to build small hardware interface. The breakout board takes the left and right channel outputs from the function generator and allows you to select which is sent to the microphone input of the oscilloscope. We found that iPhones require a 10KΩ resistor in series in order to recognize the microphone input. We added a 2KΩ resistor to divide the input voltage as a microphone circuit protection.

We then prototyped a breakout board for the students to use in class.
