Non destructive testing and imaging ultrasound have been around since the ’50s. Many ultrasound open-source projects are emerging, mostly focusing on image processing - while hardware has been left behind. Several teams have produced successful designs to be used on commercial US scanners, but they are not cheap, and are difficult to access. I couldn’t find designs to play with, that would be affordable or open, so I decided to make one for makers, researchers and hackers. The PDF here is also a ZIP that contains the sources to the hardware and some data too, don’t hesitate to have a look. Just rename the file from .PDF to .ZIP and you’re ready to go .
