Here is a tool that might help some of you in your DIY activities : WaveWatch, a soundcard oscilloscope 100% made with Processing.
I’ve just released the 1.3 version, making it a very credible, user friendly and totally open source alternative to existing soundcard scope systems, so that it’s worth sharing it !
It’s got all the features you’d expect from a standard scope,
- dual channel,
- configurable Triggering (single/Auto),
- time and voltage measurement,
- frequency calculation,
- markers with delta calculation
- voltage calibration
