Re: DU: The great laserdisc flood

Hi, Simon here (from Domesday86.com) - thanks all for the kind words about the project! I'm super-happy to see more people interested and getting involved; it's been around 2 years since Ian and I started outlining plans to recreate the Domesday system; I don't think when we started we had any idea that the project would grow in such a universal manner. The Duplicator is the third sub-project (the others were SmallyMouse2 and BeebSCSI, both of which are now in the 100s of users) and I'm dedicated to keeping it open-source/hardware all the way.

The Domesday Duplicator is pretty much bleeding-edge when it comes to LaserDisc duplication - the situation is a little 'chicken and egg' with the issues of both capture and decode needing to evolve together (and be tested together). The design had two primary aims - capture the disc (everything on the disc!) at 8 times the Nyquist (of both PAL (35MSPS) and NTSC (28MSPS)) and do it cheaply (there are professional ADC capture systems already, but they are literally 100 times more expensive and closed-licensed).

For those interested in the decoding process, I've written a high-level guide to what the LaserDisc player does (it's not 'nose-bleed' technical!):
