Sick of paying top dollar for your mixers? Yeah, so are we. But we're not so sure about building our own from scratch, even if you can get the full source code and build schematics to whip up your own Auroroa open source mixer. (They'll sell you posers one pre-built, too, if you want to front it.) Matching, scratching, and tasteful song selection? You're on your own there, pally boy.

nice fine...very interesting. i really like how the market is opening up to inventive people.
also...for those of you who are doing mods, check out front panel express to give your final creation that bling.
The white paper on the design is interesting. It has two CPUs, with one doing the USB I/O, reading the POTs and buttons, and the other CPUs sole job is to flash that RGB LED underneath! Lots of discussion of decoupling capacitors to avoid "ripple" as the Analog sampler visits each POT at up to 44khz.

Imagine the POTs are set to max-min-max-min, the resulting signal going to the ADC is going to have to switch on and off like a square wave, and square waves have a nasty habit of generating ripples on their leading and falling edges as the circuitry tries to cope with a sudden impulse of change. This needs careful control. Damn, I hadn't thought about that kind of problem.
Interesting read. They even get into choosing the right kind of capacitor for cost and speed (polystyrene are best, but they are spendy). I now realize I know nothing about electronics. Must learn more!
Awesome piece of machinery.
Really cannot wait until final pricing. ;)
Aha! There are the programming headers....

Damn, that looks sweet!

Newsflash:
Aurora did not obtain 50 orders

Hi All,
We've got some unfortunate news. Due to a lack of interest we won't
be able to sell aurora units at this time. We needed to get at least
50 people signed up to get the group order through, and we did not
evenget 20 orders.
We can't currently cover the cost of the remaining
thirty odd kits, so we'll have to postpone the order indefinitely. If
the situation changes you'll be the first to know.
The site will stay up, and we will be posting more files in a few
days for those of you who are interested in building your own.
sincerely,
the aurora team.

Yeah it didn't come with knobs and stuff so you had to source out your own, no wonder they didn't get 50 people to buy units - that would have been the straw that broke the camels back for alot of people i think.
