Hi,
I am thinking of turning the computer's soundcard into oscilloscope..
I found this circuit using CA3140 opamp operating at 9V. Since I have some spare LM358 opamp, can I use that instead and operate it at 5V instead of 9V..? Anybody tried this thing before..?
By the way, for the input 'probe' can I use a simple wire instead of the normal oscilloscope probe..? I am only using it for 20kHz and below..
The oscilloscope program I hope to use is **broken link removed**.
Please advice if possible..
Thanks..
