Project history
DSPIRA historical material and source archives
Find earlier course materials, experimental software, and complete recovery packages for retired repositories.
Useful course materials now have active homes. Browse teaching downloads and research examples.
Start with the current lessons when planning a class. The material below records earlier courses and research projects. Historical software may need older tools or unsupported hardware.
Earlier websites
Old website pages redirect to these preserved copies. Existing worksheet and data download addresses remain available. The main lab site maintains those addresses. The retired repositories no longer publish the websites.
Complete recovery packages
Each ZIP includes source files, Git history, branches, tags, and restoration instructions. The institute package also includes its wiki and historical large-file objects. Public issue and review records are included where available. Original licenses and author credits remain with the files.
| Repository | Source files | Recovery download |
|---|---|---|
| dspira-archive | 189 | Download dspira-archive ZIP |
| cra | 39 | Download cra ZIP |
| gr-dspira | 154 | Download gr-dspira ZIP |

The packages preserve original file contents, including material absent from the maintained projects. Recovery checks verified the Git bundles, source hashes, and large-file contents. See the release and verification records for checksums and source commits.
Finding current resources
Use the repository map to find maintained projects. The software guide covers classroom applications and shared GNU Radio blocks. The hardware guide covers telescope construction and circuit designs.
GitHub repository links differ from website addresses. Deleting an original repository would remove its GitHub browsing and discussion URLs. The recovery packages preserve their records, but cannot preserve those GitHub addresses.
