oscilloscope suggestions

[Daniel Pocock]

Oscilloscopes have changed a lot in recent years

Has anybody used GNU Radio to make a basic oscilloscope?

There are many generic ADC to USB devices now, some are purpose-built
for use as an oscilloscope.  Has anybody tried any of them in a pure
free software environment, either with GNU Radio or other software?
Examples[1] on eBay.

There have also been some open hardware projects like ScopeFun[2], has
anybody tried it?  They sell[3] it for $750 and the software is all
free, open source.

This area is probably quite interesting for hams, hobbyists and students
who don't have money or space for full size lab equipment.

Please note I'm not only interested in RF-oriented analysis here, some
people may simply want to analyze their audio signals, Arduino PWM
outputs or some other things below RF.

This could also be a useful topic for one of the proposed GNU Radio
amateur radio workshops.

Daniel
