pyscope
A modern software oscilloscope. Plug in leaders to an audio patch cable and watch your circuits live!
xoscope hasn't had a release since 2009, so this is a remimplentation of it: shorter, in python, and more flexible. That's the end-goal, at least. It will probably languish as a hobby project, but pull requests are welcome!
Built on SciPy and PySoundCard :)
Installation
First, clone this repo.
If you can get the dependencies installed on your system, pyscope should run on Windows, Linux, and OS X.
Pyscope is a py3k application, so you need to get SciPy, matplotlib, and PySoundCard installed in their python3 forms. SciPy/matplotlib are almost certainly available in your distribution's package manager or are available from http://scipy.org, but PySoundCard might not be. However, it is on pipi and you can install it with "sudo pip install PySoundCard".
Running
In the directory you have the repo cloned, just run 'pyscope'. You should see something like
.
Hum at it and you should see something like
If you see the scope but do not get a response, check your volume settings.
To use pyscope to test electronics, you will need to build an 1/8th" TRS probe pair, using, for example, these instructions. Be careful though! Running experimental circuitry direct into your computer might not be advised. Find someone with the skills to make you a voltage limiter.
Does not yet support the ability to choose which soundcard to listen on, but that is in the works.
