Here is a Soundcard based oscilloscope hardware with overrange detection and complete PC protection. MAX input magnitude 200V (with 10X)Both Audible and Visible Overrange DetectionProtection, when signal is present but no power supply Finished Hardware at Testing Stage  7555 Astable Multivibrator  50 Hz Mains Supply  50 Hz Mains Supply (After filtering with 140 Hz cutoff freq software low pass filter)  Protecting Soundcard from Excessive Input This circuit is fully tested with 50V input at 200mV range without 10X attenuation. So if u built it correctly it should work. I will not take any responsibility if u cook your motherboard or soundcard with this !!!!! www.virtins.com (we need crack for version 3.0) www.zeitnitz.de/Christian/Scope/Scope_en.htmlwww.sillanumsoft.org/ |

Hi,
I wonder if some one has made measurements to define the specs of this design ? specially frequency limits and response accuracy on the edges of the sound frequency range for example starting at 20Hz and going below for lower range and starting from 20KHz and going above for the upper range. also if any one has made tests for the linearity inside the sound frequency range. or we have to apply corrections if the response is not linear ?
Regards

Does this work with every soundcard? How do i know if my sound device can process signals greater than 20khz? aren't soundcards/sound driver IC's capped to filter only 20hz-20khz through?
also, does anyone know of the reverse? a pc soundcard based function generator schematic? Can someone tell me. Thanks

I have experience on making oscilloscope that was used on GameBoy only. The GBDSO is my first project. It can be used with gameboy.  |
