There's a direct link from the main page - Mini Synth Modules

That's the intention :)  The next batch will have both solder-resist and
silkscreen legend, much better than the prototype board in the pictures.
The left picture is the older one, with a test resistor in place of the
tempco.  The newer picture on the right shows the tempco glued to the body
of the NPN-pair (a 2SC1583 in this case).

Is this this sort of thing you're looking for?

The next batch of boards will be significantly cheaper, per board, than
the prototype---my target is £4/$6 per board, or cheaper if I can do it.
If I bought them in really large volumes I could do them for $5 a piece.

Cheers,
Neil
