Im in for at least 4 and maybe more.

Bring on the Buchlas

Please

HMMM just noticed the $12 a board possibility I dunno...

If it can come in there I will be more interested in like doubling up to 8.

Hmm, 3080's huh?
I know they're not exactly unobtainium, but I'd happily jump on the "talk him into using 13700's" wagon, as I've got loads of them, and they're not obsolete...

I'm wondering if each board is 1 "AD" section of the Buchla Module (plus the bottom or section?). I don't quite understand.

But I have been wanting to somehow reproduce the function of this Buchla module with ken stone slope detectors for some time...

I'd take up to 4, depending on how it works (if I need 4 for one complete module).

Count me in for two, pending price.

wow- good responses so far! hey and by the way i just bought a Simmons SDS800 with pads for $50! exciting stuff. hope it works...

so first: the ordering stuff (questions answered below that)

it looks like it is a go then, judging by the numbers. i guess the next step is to get a realistic count of the actual number of boards- a "firm" commitment, as it were.

i do ask that it be pretty firm- because i am putting up all of the cash up for the initial order- and i don't have alot of slack in my budget really. the revised board is about 75% done out in CAD (the original was done in Illustrator)

I expect to be able to place the order in the next 2 weeks, with about a week's turnaround, assuming there's no problems. I will then build and test one set to make sure all is good, then i will take money and ship out. all in all, about 5-6 weeks from now. hopefully this is OK by you all.

so, next i ask that everyone that is in- send a PM in the next few days with your desired quantity. i will take that count and get an exact price in order- post it here, and then ask for final revisions to orders...

i will probably get a few extras, but not too many..

i will then send out email confirmation to everyone with my paypal info. if you prefer to pay some other way, let me know. shipping will be standard postal service-

to those overseas, what is the best way to describe the PCB[s] on the customs form? spare parts?

ok now for questions:

Perhaps a small donation to Don Buchla as well, who is still marketing this basic design as part of his income?

Then again, this didn't stop me from ordering some Wogglebug boards, and Grant is still making that Sad

3080's availability - I'll have to do a count, but I MAY have some available for any who will need for this board: I would much MUCH rather do a parts trade, rather than cash. Smile

I'm open to parts suggestions.

If my MEMORY count is correct, I can spare about 10 as I'd like to keep 10 to 20 for my future stuff. (I'm still slowly converting to LM13600/LM13700's.)

Lemme know if any interests. Smile

(Immediate trades that I'm looking for, as an idea - though still open to other offer ideas: 12 position 1 pole rotary switches, new; 1 meg linear pots (1/4" shaft); pink, super bright LEDs; LF412's (or other higher end type opamps, such as those that Ian uses in things. Wink

)

i'd like to have two of these boards of canada, please. Smile

I'll get 4. But if they get cheap enough some more.

PM sent! But uhm..apart from the 3080's, is there anything else that might be hard to find in this circuit?

Edit: I see on the schem, that AD821 pnp-pair is used - do you provide pads for discrete transistors, ssm2220, or perhaps 2SA798?

not to put a damper on things but didn’t realize that this was still an active product of buchla's, and considering that it is, your posted "perspective" is kind of hard to agree with. as much as i would like to have a bunch of these boards i know how i would feel if someone were offering boards for my own active designs, so unless you can somehow get permission or something i'm going to have to cancel my order.

it just doesn't feel right

Fernando · Posted: Fri Jan 18, 2008 12:39 pm Post subject:

It feels very good to me.

The schematic is public and we would make boards for ourselves, each.
What Josh is doing is generously organizing a group pcb batch so the boards have better quality than home etching ones and are cheaper. He's not doing bussiness. So it is a favor to some friends. That's why we are together in this forum.

And, this is a very old schematic, no doubt current units will differ.
And current schematics of actual units are not public, we can't build them.
This is hobby stuff... a bunch of people resurrecting old circuits

you are certain that don released them to the public with this intention?

if we can be sure that this won't upset him then i'm cool with it of course. i really want these, but if he's even the slightest bit upset then its not worth it to me.

i'm not being crazy here am i? this is just common decency

Fernando · Posted: Fri Jan 18, 2008 1:38 pm Post subject:

... I never even thought of asking because I don't consider this to be any competition to his products... this pcbs are not even a product

are bare pcb for own experimentation...!

bubblechamber · Posted: Fri Jan 18, 2008 3:51 pm Post subject:

I'm going to have to aide with Fernando and Josh on this. Even if those schematics were not released for public consumption, they are very old and very likely do not reflect the current 281e which probably a microprocessor like much of the new e series. if Josh were offering commercial modules of the 281 or scanning and redrawing the original PCB, maybe that would be a problem, but Plan B has used that essentially as their business plan from the beginning and Doepfer has released several modules based on Buchla designs as well. And it seems unlikely that these 281 boards will impact any future sales of 281e modules.

just some general questions: How long does copyright last on a schematic from the 60's or 70's(like Moog and Buchla)? and what if that company no longer exists(like Aries or Polyfusion)?

This seems to be a pretty complicated subject and there are tons of cloned gear on the market, are they all working in a gray area? I find it hard to believe that Roland gave permission to all the 303 clone makers.

i can agree with most of that and i myself will be cloning long out of production designs to some extent, its just the idea that its an active design thats getting under my skin. no this isn't taking any potential sales from buchla (as far as we know) but that has nothing to do with it. i understand that there is a good chance that the design has slightly changed over time as well but that is also besides the point. the simple fact is that someone spent a lot time and effort to design this circuit and in one way or another he IS still relying on the design for income

if this were someone that you can easily get in touch with and interact with like say ... thomas henry and he was STILL selling the product in some way, shape or form would you feel the same way regardless of whether you could afford his version or not?

if roland were still making an analog 303, even if it were version 50, you can believe that they would put a stop to all the cloning.

some people say that 20 years is the life of a u.s. patent but i have no idea myself. i can’t believe anybody’s rant about it, and they are often renewed, or have odd circumstances so i’m not sure what to believe

i’m really not trying to be difficult or talk anyone out of this. i want them too!!!….. but i have a conscience
