Progress of DIY-PCB (long)

[Roy Tate]

Last weekend, I offered to collect PCB ideas and wishes from
various list members.  Here are the results ...

Standards:
* MOTM sizes, 1/4" jacks
 (5 votes)

* Full 19" width, 1/4" jacks (1 vote for jacks mounted to PCB)
 (6 votes)

* +-15V supply
 (4 votes)

* +-9V supply
 (1 vote)

* +-10V signals
 (1 vote)

* 1 sqr dm (4''x4'') double-sided 'green' pcb w/ silkscreen
 (1 vote)

Projects:
Interpolating Scanner (11 PCBs)
    http://www.synthfool.com/diy/jh_ipscan.html
40235 Filter (11 PCBs)
    http://www.netcontrol.fi/~jocke/arptech/40235/
Moog Filter (2 PCBs)
Temperature Stable VCO (1 PCB)
Wasp type of Module (1 PCB)

Tom G's Sequencer (12 PCBs)
 - Tom will be handling this PCB.

Help so far:
PCB layout, Panel Art

Who am I?  No one special.  I don't claim to be a designer, and
I won't be starting now, but it looked like someone should step
forward and start organizing this.  All I want are some unique
PCBs.  I'd be happy to hand this over to any other list member.

What are my motives?  To get some PCBs.  :)  That's it.  I 
would like to suggest that we concentrate on one board, with no
promises of more until this one is finished.  I'd like to avoid
circuits that are planned or in production from MOTM, PAIA, MAP
or Blacet.  Furthermore, I would like to recommend that we build 
a PCB for the Interpolating Scanner and make sure it COULD fit
behind a MOTM panel.

What is the plan?
1) Select a circuit
   I don't need 20 of any PCB, so there has to be enough
   interest in making the design.
2) Consult circuit designer for changes, modifications, etc.
3) Group discussion to select parts for things like the 
   CA3080, CA3280, LM13600, LM13700, and SSM2xxx.
4) Several helpers will breadboard the circuit (including 
   any modifications)
5) Some lucky person will build the PCB files as required
   by the PCB manufacturer.  The circuit designer may request
   that his/her name be printed on the PCBs, or not.
6) Someone will finance the PCB run (maybe me)
7) PCBs will go to the financer, and/or someone in the country 
   where PCBs were built.
8) I will give one or two PCBs to the original circuit 
   designer.
9) Circuits will be sold "at cost" plus shipping.
   This will be tricky, unless someone has the resources for
   credit card processing, secure web page, etc.
   We might try having a US, and a European "distributor."
   I'm open to ideas and suggestions.
10) If enough people want a common front panel, we can look 
   at that next.

If this sounds like alot of work, well it will be.  I imagine
that the project is guaranteed not to make a profit, but ...
if any profit is derived from this project, it will be split
equally between the helpers (but not me!), or donated 
to charity.
