Pit-Perfect Laserdisc Backups with Domesday Duplicator & LD Decode #DataPreservation #Laserdisc

Pit-Perfect Laserdisc Backups with Domesday Duplicator & LD Decode

Thanks to Jason Scott on Twitter we learn of the Domesday laserdisc pit-perfect duplicator project.

The LaserDisc RF duplication system has now been tested successfully on a number of different capture set-ups and high-quality NTSC decodes have been produced by the ld-decode sister-project (proving the end-to-end viability of the LaserDisc preservation capabilities).

The Domesday Duplicator is a USB3 based DAQ capable of 40 million samples per second acquisition of analogue RF data.

The hardware is a USB3 based 10-bit analogue to digital converter designed to allow the backup of Domesday AIV LaserDiscs (as well as generic laserdiscs) through the direct sampling of the RF data from the optical head (laser) of a LaserDisc player.

Included in this release is a completely rewritten capture application which is more efficient and has many new features to assist with the preservation of LaserDiscs.

One driver for this is preservation of the British 1986 Domesday project:

Domesday86 is a project that aims to recreate the experience of the original BBC Domesday project using modern hardware and software. On this site you will find a growing collection of documentation for the original Acorn/BBC Domesday project as well as details of the Domesday86 project itself.

Below is an interview with Simon and Chad of the Domesday Duplicator / LD Decode projects – A combined hardware and software effort to achieve bit-perfect rips of laser discs!  This project is extremely important, as aging laserdiscs have a finite lifespan and will soon be lost forever if not preserved.

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
