There aren’t any, nor will there be. I’ve put everything I’m going to on this website. Please don’t email me asking for kits, or parts, or soft-copies of schematics, or PCB files, etc etc. The answer will always be no. It doesn’t matter if you “need” it for a student project, or to rescue your dog from a burning building: the answer is still no.
Despite this, I know from experience that some people will still email me to ask. Sigh.
The intent of these webpages is to provide a lot of information to help you design and build your own signal generator. On these pages are schematics, source code, and detailed descriptions of how it all works. For most people this is more than enough.
