Modular synth schematics

Looks like Modulus Electronics has some good PDFs full of info and schematics to be used in synth building located here
as part of the Modulus E-Zine. Another interesting thing to check out is the Synth-DIY UK expo. All kinds of synth porn there, with an occasional Casio keyboard and a Speak lurking in the pictures. ( Thanks to Synth-DIY list for the tip )
