UPDATE: THIS OFFER IS NOW CLOSED. I WILL NOT BE HAVING ANY FURTHER BOARDS MADE
Sounds like a case for a Kickstarter crowd funded project?
Or in your case, Pozzible for Oz.
Dave.
I'd be interested about notch filter, provided a little bit better documentation. Either ready-made or PCB only. I have AP and dScope audio analyzers, so I can asses how good that is.
I would be interested but I'd like to have some idea of cost before committing...
OK, thanks to Google I now know what "Kickstarter" and "Pozible" are. Intetresting concept. On Pozible one guy seems to have >$19k for sticking RGB LEDs into a hoola hoop! 
How many of these projects actually come to fruition in the end? Some seeem pretty ambitious, some completely stupid. Cast your net wide enough and it seems you can sell almost anything.
Err, you haven't been following Kickstarter then! (there is another recent thread on it).
Every kid in his garage is getting 6 or 7 digits for any idea they throw out there. 5 digits is practically guaranteed on Kickstarter for any flashing led board.
How about $313K for a micro on a board?
http://www.kickstarter.com/projects/digistump/digispark-the-tiny-arduino-enabled-usb-dev-boardAn example of a simple bare board that met it's very modest funding target:
http://www.kickstarter.com/projects/671510748/superlf398-low-parts-count-sample-and-hold?ref=cardPozzible is much less simply because it does not have the market presence and hype of Kickstarter.
How many actually deliver? Well, almost all of them are later than promised because so many underestimate how much time/effort it takes to manufacture stuff. And some completely fall through and deliver nothing after a year or two.
There is so much failure that Kickstarter have recently changed the rules to try and stop "pie-in-the-sky" ideas getting listed.
But if you need money up front, and effectively get "pre-sales", it's well worth considering.
Dave.
Thanks Glen! I'm in for one board. I'm in the USA. I would prefer plated through holes, solder mask two sides, and silk screen one side.
You may be underestimating your market based on low sampling frequency. Post an article in rec-audio-high-end and one in rec-audio-tech and see how many responses you get.
Just put the quotation in the cart, and it will show the shipping. You can still abort.
As for the oscillator demand, I gues it will help to 'sell' it a bit more; where are the images of the PCB, a bill of materials, maybe a finished build cost estimate, technical specs such as power supply & consuimption. When you have all these things together, more people will be interested. Heck, even I might be
Wow, that's a lot for shipping a board! The price for the boards is good though. It's less than what I can get here in the USA. Let's hope there's more interest in this board. How many do you have interested so far?

I think that $17 is the total cost with shipping [(298+50)/20=17.4].

Count me in for one board.

Count me in for one please.
So, you have 6 total so far.
Hi Glen, which trimpots did you use for this oscillator? Your BOM only says "trimpot", but there are many different kinds. Thanks.
Hi,
These ones:

There are other brands of the same thing. Just make sure to order the style with the three pins in line. There is one variation with the center pin (wiper) offset.
OK, thanks. I'm almost done with a Mouser project that has almost all the parts. Mouser doesn't carry Analog Devices so they don't have the AD8226.
Will it run just as well on +/-12VDC instead of 15VDC? I'm thinking that I'd like to run it off of batteries and 12VDC is more convenient than 15VDC.
How do you control the output voltage for this oscillator?
Thanks Glen! much appreciated!
OK, I'll let you know when it arrives. Thanks again for all of your hard work and generosity.
Hi Glen, I got my board today! Thank you!
