Resonant Lopass Gate PCB's (New Batch 4/29/12)

[flts]

I'll take two PCBs... Thanks!

It's pretty much trivial to make a power adapter anyway so no problem for us Euro users.

I'd definitley be interested in one of these boards.

[mono-poly]

16 please

[e-grad]

4 please!

[oshidash]

Please count me in for 4. Thanks!

[JCM]

4 for me please!

[henrikgo]

2 for me please!

I'm interested in 4, thanks!

[wmonk]

Count me in for 1 or maybe 2.

Hi all,

All I can say is "Wow!"

I had no idea it would be such a desired PCB project. I figure people would want a couple maybe, but some are ordering 8 or 16 at a time. This is great, but this will also require a significant upfront cost for me to produce the boards. I will have to limit the number of boards being produced, and potentially fill the orders in batches.

The bad news... I am going to have to cap the board run at 200 PCB's! My financial analyst (Wife) is already going to "not be thrilled" with the investment I am putting into this project right around the Holiday time. But, I am a synth junky and I know you are too! So the boards WILL come...

Okay, that's it for now. Off to start double checking circuit paths and such. More to come later,

Thomas

PS. Attached is a new full-color image of the PCB. BUT, do not be fooled. The production PCB will be standard green with white silk screen.

as from the previous thread, I would like 8 boards, please.

just to mention: i would actually double that request, based on reading that this is a one-time run of boards. but out or respect to the cap on the total runs, i'll stick to my original. (i suspect that some of us are stocking up a bit based on that one-shot stipulation, tho not me: thats 1 quad unit each for 2 of the formats i use most) i would also be willing to prepay if the thats the limiting factor for you, although i understand that this is generally not a great idea.

finally and again: thanks to you and all involved for this valuable contribution to the DIY community. thanks also for your care and respect for both Don and other vendors--that kind of ethic is very important to me, and i'm proud to see that it really is the norm among SDIYers.

I would like 8 boards please.

[Dave Kendall]

If it's not too late, I'd like 4 boards please....

cheers,
Dave

Only ten left from the run of 200 to be reserved. If other requests come in after that, they will go on the first-come, first-served list for flake orders or cancellations. Version 1.6 is complete and the traces look good. I will order more proto's this week if I can to get this project to the final phase.

I know this whole order has been on the weekend. I think maybe more orders will come through on Monday when browsers are back at work. I'll keep any additional demand in mind and try to get together a *possible* second run. This is completely hypothetical at this time and I cannot promise anything. So, keep posting your interest so I can tally the overall interest in the project. Again, I did not think so many people would be wanting 4 at a time for quad units. With the extra board features like resonance and the input stage these quad units could be quite large.

I'm now moving on to schematic, wiring diagram and build docs. These will all be provided electronically to save paper. The boards will also be ROHS for environmentally focused status. Thanks again, more to come later!

I take 4 Boards, thanks

[Sine]

4 boards here please,

Payment up front would be no problem at all

[vtl5c3]

If not too late, I'll take 6 more, making for a total of 8.

i just want to echo some of the previous posts and say that for one, I'm extremely grateful to Mr. Buchla for giving this project his approval - very generous and kind, thanks.

And, equally, I'm very happy to see that Thomas is doing everything in his power to make sure this project is as ethical as possible - clearing the whole thing with Don, making sure not to interfere with manufacturers who are selling similar projects in certain formats, etc.

The whole thing is just totally classy. Well done, this is something to be proud of and I'm happy to be able to get involved with such a good project. Excellent work gentlemen, this is how it should be done.

thanks for all your efforts Thomas

[djthomaswhite]

All boards of this initial batch are spoken for, provided all who spoke with interest will follow up with payment when invoicing time comes.

I appreciate the words of support on the project. The only way to do anything is the right way. Yeah, it takes longer to get it going and off the ground but it feels better in the long run.

Again, please continue to express interest (if any) in future "potential" runs of boards. Thanks!

BTW, Here is the modified schematic document (just finished).

I'm interested if any boards become available.

[LektroiD]

How much to ship a couple (2) over to the UK?

Sorry if this has already been asked

[djthomaswhite]

What a long weekend in front of the laptop,

Here is the parts list for the PCB's. Even if the board has an error or two the parts listed here are what will end up in the final production run (plus or minutes a few mods from any last minute additions). Have to throw that caveat in there to be safe.

Still working on shipping International. Domestic US shipping will be included in the price of the PCB. I'm trying to find nice padded envelopes but want ones that are recyclable to be 100% in line with ROHS, my affinity to Green living and, well... just because really. More to come soon!

This whole weekend has flown by. I will not be working on anymore build docs for now. This post has the existing board layouts, the schematic and switch wiring diagram, and now the parts list. I will only make some sort of instructions if due to popular request. The PCB legend shows the part values and the wiring will be specified on a yet to be produced wiring sample diagram. This will be put together after the proto run and final testing before production begins. Thanks folks,

Thomas

[apemandan]

put me down for 2 boards! Thx

[stijn]

unbelievable, missied this one!!

I'm up for 4 boards definitaly!
