[sdiy] using off the shelf pcbs in a commercial project

[Dan Snazelle]

ok


my project has a simple but i thought good lm566 vco
an lfo (of which i could buy ken stones utility lfo)
a great sample and hold with smooth and stepped (which pcb for this one...hmmm)
tons of routing (i think) for  basically a super super powerful guitar effect (no pcb for my routing. thats just going to be a ton of wires isnt it? with tons of buffers-that sounds like a nightmare to figure out. but i will figure it out. it will be easier once the panel is done and in front of me to put the pots on.
a decent a/r
tons and tons  of dividers
an audio to gate module with cv out (env follower)
a lag

a solid vca (lm13700)
i am working on a vclfo for it (of which i guess i could buy wilsons vclfo)

and on and on

its a serious project with about 60 panel controls.

25 toggles, 30 pots 10 rotary pots 6 leds


so my concerns with using other peoples pcbs are this:

1. what if the device has enough demand where more than one person wants it (i doubt this will happen but it might happen that more than one person will want one based on seeing this one) then i have to order boards all over again from 3 or 4 places instead of having all the boards myself


wouldnt it be harder but better to use app notes stuff that i know no one will get mad at me for using ,    all tied together on boards that are meant for the project?


these are some things i need to start asking

that soundlab could really do some utility stuff for me. i could use my own vco, my own ssm2044 filter, my own f to v/divider nonsense, and my own routing.

BUT what are the long term implications of such a thing? seriously. i dont know what legal rights the purchaser of a pcb or the seller of one has.

if i put ken stone pcbs in a commercial project will it mean ken stone has a right to a percentage of my company? seriously how does all that work




thanks

> Well, however you make the boards, here is some advice:
> Don't try to make just one big board.
> Break it into logical bits, eg the VCO part, the VCF part etc etc.

> And if there already exist boards for some sections -
> feel free to use them! ;D
