Just FYI:

Those are two separate projects.

The Digital D43 project is mine. In addition to the linked wiki page and the Github page, I also have a bunch of blog posts about the software and my old D43 oscilloscope.


The video is of the Fads to Obsessions Webcam Oscilloscope project.

The only connection between the two projects is that I couldn't get the Fads to Obsessions software (written for Windows) to run on my OpenSuse (Gnu Linux) computer. Many Windows programs will run under Wine on Linux, but the Webcam Oscilloscope wouldn't. That forced me to write my own software, which has its own set of features.


The Digital D43 software I wrote runs under Windows and Linux, and probably on Mac as well (I don't have one to try it with.)


Digital D43:


Click the image to open in full size.


Besides on screen cursors, the D43 software can digitize the trace and save the data to a CSV file for other use (I sometimes load the CSV into Baudline to generate a frequency spectrum plot.)


The software can emulate a DSO (display only the digitized trace) or display the live trace and the digitized trace at the same time.


The picture above doesn't show it, but when the digitized view is active there is an RMS display in the voltage section.


The software can be used with (nearly) any webcam, and can be used with any analog oscilloscope.

Hi Joseph
Welcome to the Forum.
Thank you for droping in and informing us over your really useful SW.
In due time I will try to use it, now I a bit off the bench.
Keep up the good work


George

Hi, George.


The diyaudio forums showed up this morining in the Github insights page (visitors) of the D43 project. I hadn't heard of the site before that.


Thanks for posting the link to my software.

Joseph, you are welcome (*).
I appreciate such work as your’s and the ‘give it to the community’ mind set.
Please take your time to navigate around this site, I hope you’ll enjoy member’s activity (not the bad guys )

(*)It was a young aged and bright member that discovered your work. I only relayed it here (the present and the future belongs to the young generation )

George

Wow! What a cool project. When I saw George's post I imagined it was hacking into the scope to digitize the signal with a fancy ADC. But not at all. This is completely non invasive.
