The Oscilloscope is ready for use!!
Below are several voltage signal tests, among others signals from mobile phone charger, laptop charger, battery, etc.
Sample of close-to-perfection voltage signal without noise.
NOTES:
1. This Oscilloscope could be used for a maximum input voltage of 5Volt.
2. This Oscilloscope has a frequency range of: 20Hz to 20 kHz (complying with the Soundcard capability).
3. The value of 22K Resistor could be increased up to 820K Ohm for the use of Oscilloscope with an input of above 5 volt.
4. The value of Potentiometer could be increased up to 100K Linear, for the use of Oscilloscope with an input of above 5 volt.
5. For safety of your Laptop, you can use cheap USB SoundCard (under $5).
Good luck.

Pc Scope Software
Zelscope pop - Zelscope is a Windows software that converts your PC into a dual-trace storage oscilloscope and spectrum analyzer. It uses your computer's sound card as analog-to-digital converter, presenting a real-time waveform or spectrum of the signal - which can be music, speech, or output from an electronic circuit. Author: Christian Zeitnitz. Main features: The PC based Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution. The data source can be selected in the Windows mixer (Microphone, Line-In or Wave). The frequency range depends on the sound card, but 20-20000Hz should be possible with all modern cards. Zuma game download. Macdrive pro 10 serial. Soundcard Scope is a software, free for non-commercial use which uses the soundcard of a computer and shows signals coming in from the soundcard as waves in a scope on the computer screen. The software has many features which make it quite useful and at par with expensive oscilloscopes. It can record a signal, show relevant measurements on screen. BIP Electronics Lab Oscilloscope - Freeware windows oscilloscope uses the sound card's input to measure signals. This means that the quality of the scope depends on the quality of your sound card. The scope automatically uses the highest sample frequency available at the input that you select.
