Domesday Duplicator (DdD)

Please see the Project Documentation for details of the project and for access to the project documentation.

For contributing guidelines, see CONTRIBUTING.md.

The Domesday Duplicator is a LaserDisc capture focused, USB 3.0 based DAQ capable of 40 million samples per second acquisition of analogue RF data at 10-bits resolution.

Capture is via a easy to use GUI capture application.

Cloning the DomesdayDuplicator GitHub

The Domesday Duplicator project uses git sub-modules to cleanly separate the distinct parts of the project:

• DomesdayDuplicator → system / integration
• DomesdayDuplicator-hardware → PCB / KiCad / fabrication
• DomesdayDuplicator-firmware → FPGA / GPIF / USB3
• DomesdayDuplicator-gui-app → GUI / Host USB
• DomesdayDuplicator-gui-docs → Documentation website contents and deployment

To clone this repo and all the sub-modules use the following command:

git clone --recursive git@github.com:simoninns/DomesdayDuplicator.git

The Decode Family

The samples the DdD capture can be used with the whole family of decoders that make the FM RF Archival workflow ready to use today.

The original design was for the wide bandwidth of LaserDisc RF - making it suitable for all of the more bandwidth restricted mediums too (that have a single stream of RF).

Please see the documentation for more details

3D Printed Case

The DomesDay Duplicator also has a 3D models and ready to use STL files for producing 3D printed cases, to protect from dust or line with copper tape for affordable EMI shielding for example.
