[sdiy] Single-sided ASM-1 board designs

[synth at charlielamm.com]

Stephen:

I am not sure if you mean the ENTIRE asm-1 synthesizer as single-sided or
just individual modules.  Sounds like the latter....

You can find the VCO at my web site: PCB design, links to schematics and
build notes, a calibration technique, eetc.

Before you run right out and press and peel the design however, one
important caveat: what's there isn't 100% tested.  I designed a board
very, very close to this one and fab'd a one off at home using press and
peel and it worked: all waveforms OK, all features OK, it cal'd OK, etc.
however, after doing so I realized I could get rid of a jumper by doing
some minor reworking of the V- rail.  So I did.

The design that's there was sent out to APCircuits, and I have gotten back
2 PCB's of the exact design.  I still need to test it.  I have mixed
feelings about putting stuff out there that isn't _completely_ tested,
but, as I say in the site, what's at the link above is either 100% good to
go or very close.

If you want to be conservative, you should wait until I build up the 2
protoypes.  I will let you know if I have success.  I should have this
done in the next 2-3 weeks.  Or, just get what's there now and let me know
how you do.
