Hardware component to the Domesday86 Laserdisc preservation project.
The Domesday Duplicator is a high speed RF sampler that is used to make backups of Laserdiscs.
When connected to your Laserdisc player's laser RF test point (not the "RF Out" on the back of your player!), the Domesday Duplicator creates a frame-by-frame backup of all the data contained on the Laserdisc. This backup can then be decoded using the ld-decode project, resulting in preservation-quality video, analog audio, digital audio, and even data tracks.
Laserdiscs (including LaserActive/Mega-LD) are the primary use-case of this hardware. However, there is currently work on VHS decoding!
In this listing you can purchase the assembled Domesday Duplicator board or the complete kit. The complete kit includes the pre-programmed FPGA and Cypress FX3 USB boards. Both of these are required for the Domesday Duplicator!! If you do not purchase the complete kit, beware that you will need to source the other two boards and program them yourself. You will also need a 50ohm BNC coaxial cable to attach the DDD to your player. The software is available at the Domesday Duplicator Github.
As documented on the Domesday86 homepage, the Domesday Duplicator must be connected to your Laserdisc player's internal RF test point. From there, connect the device to your computer and start the capture app.
