The chronology of standards converters is covered in a couple of the articles on my website. To summarise, ignoring optical methods and apologies for any inadvertent omissions.
BBC CO6/501 and CO6/501A analogue. Also built by Pye for ITV
BBC CO6/509 digital
The first amateur built converter was a one-off by David Boynes in the 1980s. Several others have also made one-off converters. Darius's design is notable for being fully analogue, using CCD delays originally made for TV sets. There are also PC based solutions. Kat Manton did a Linux based system "FotHTV". I think others have done work with tweaking Windows to give 405 output. I suspect Peter Scott will be able to give more detail here.
Commercially available designs marketed to enthusiasts:
Dinosaur (Dave Grant and Mike Izycky)
Pineapple (Jim Daniels from BBC OBs)
Domino (Malcolm Everiss)
Original multistandard Aurora (Darryl Hock)
Aurora SCRF series (Darryl Hock)
Aurora World converter (Darryl Hock)
Hedghog(Frank Cuffe) - this is an open source design, fully built versions are not on the market
The Aurora SCRF is still available. The last time I asked Darryl the total sold was over 700. Almost all to the UK, almost all the 405 version.
The Hedghog is open source hardware and software, hence free to replicate by anyone who want to have a go.
