Main features: The PC based Soundcard Oscilloscope receives its data from the Soundcard with 44. Hz and Bit resolution. In essence, an oscilloscope is a data acquisition box that records the voltage from your circuit.
Another device on your computer already does this: the sound card. The main differences are the level of voltage each can handle, and how fast they sample the voltage (more on that later). Sample of close-to-perfection voltage signal without noise.
This Oscilloscope could be used for a maximum input voltage of 5Volt. The value of 22K Resistor could be increased up to 820K Ohm for the use . If you have a PC then you. The software that I used in the article.
Zelscope is a Windows software that converts your PC into a dual-trace storage oscilloscope and spectrum analyzer. Sound Card Oscilloscope , free and safe download. Various software packages enable the stereo sound card found in a personal computer (PC) to provide oscilloscope -like displays, but the low- sample-rate, high-resolution analog-to-digital converters (ADCs) and ac-coupled front . This is a simple project that anyone can build.
