UNI-T UT2025B Digital Storage Oscilloscope

Image

This is the best scope of the H.A.C.K. right now, I attached the repackaged official software (smaller and extractable by free software) and the official documentation in PDF. The official software runs only on Windows 2000 and XP, and is capable of taking screenshots and saving them in BMP format, but only when using the USB interface using its custom driver.

Experimental screenshot capture with Python

The code can be found in the GitHub repository of the project(external link) and is available under MIT license.

Screen colors (as transmitted via USB)

Although the version H.A.C.K. has is monochrome only, a 4-bit color bitmap is transmitted via USB. The following table contains the 9 colors I identified so far, feel free to extend it if needed.

As kounst pointed it out in his comment on Hack a Day(external link), there is a similar, more advanced project going on with the same goals.
For the purposes of commiting contributions and resistance against centralized infrastructure, I mirrored the SourceForge Subversion repository to a GitHub repository(external link).
