Title: Soundcard Oscilloscope Hardware !!! by MAXPAYNE Post by: MAXPAYNE on February 21, 2008, 07:54:17 19:54 Soundcard Oscilloscope Hardware !!! 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 Detection Protection, when signal is present but no power supply (http://img216.imageshack.us/img216/204/dsc00528px1.jpg) Finished Hardware at Testing Stage (http://img228.imageshack.us/img228/5002/7555bx0.png) 7555 Astable Multivibrator (http://img90.imageshack.us/img90/2719/sinekz3.png) 50 Hz Mains Supply (http://img141.imageshack.us/img141/7/sinefilterfu6.png) 50 Hz Mains Supply (After filtering with 140 Hz cutoff freq software low pass filter) (http://img90.imageshack.us/img90/4665/osciclipxr9.png) 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 !!!!!

congratulations for ur sucess....... if possible please give the schematic in pdf format. i need osc'pe for my lab. also name the software u r using for measurment. thanks in advance chen Title: Re: Soundcard Oscilloscope Hardware !!! by MAXPAYNE Post by: MAXPAYNE on February 25, 2008, 06:44:38 18:44 I don't know why u r asking for pdf schematic ....everything in the schematic is clear enough to read.....
I am using virtins multiinstrument 3.0 trial version......... 53 times downloaded and only 8 thank you..!!!! Looks like people have to pay to press the Thank you button. They don't want to use "Thank you" but they keep writing thank you in the post ! thanks in advance u r thanking me in advance but u didn't use thank you button.......Amazing !Title: Re: Soundcard Oscilloscope Hardware !!! by MAXPAYNE Post by: seaspac on March 05, 2008, 11:21:45 11:21 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 seaspac Title: Re: Soundcard Oscilloscope Hardware !!! by MAXPAYNE Post by: jeanninemtv on March 05, 2008, 05:19:38 17:19 interesting gadget!!!
maybe we can find virtins full Title: Re: Soundcard Oscilloscope Hardware !!! by MAXPAYNE Post by: felipito on March 09, 2008, 12:36:29 12:36 Circuit that is required to work 100 kHz? Interesting
Title: Re: Soundcard Oscilloscope Hardware !!! by MAXPAYNE Post by: persiangulf on March 09, 2008, 12:47:52 12:47 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 Title: Re: Soundcard Oscilloscope Hardware !!! by MAXPAYNE Post by: otakis on March 14, 2008, 09:58:09 21:58 hi,
how much does it costs? does it works in a notebook? thanks Title: Re: Soundcard Oscilloscope Hardware !!! by MAXPAYNE Post by: MAXPAYNE on February 16, 2009, 01:03:42 13:03 How many of u has built my oscilloscope ?
Please post your feedback if anyone has built it ...... Title: Re: Soundcard Oscilloscope Hardware !!! by MAXPAYNE Post by: mayli on February 17, 2009, 04:22:48 16:22 I have experience on making oscilloscope that was used on GameBoy only.
The GBDSO is my first project. It can be used with gameboy. ;D Title: Re: Soundcard Oscilloscope Hardware !!! by MAXPAYNE Post by: manish12 on July 05, 2009, 05:04:10 05:04 pcb layout ??
