Parts and boards for the first three are on the way! I'll order the next set of three once I know these work and are reasonable to build.
@Tobor, @jahall4, @bandman444- are you still interested? I'll only have two to give out in this batch but as soon as I can verify the design I'll order more.

Hi again all!
It's been a while- I've been busy with other commitments, and computer issues have left me scrambling to recover some of my work. But anyway, I'm still working on this project. I've had a few good test flights since I last updated you all, including one to 3000+ feet, so I'm feeling pretty confident that ArdIU is close to beta-testing ready.
@Tobor, @jahall4, @bandman444 - sorry to ping you again, but I just want to double check whether you're still interested in beta testing.
On that subject, I'm getting close to ready to ship beta kits. The cost for a kit will most likely be around $30 plus shipping and require assembly of a similar difficulty to an Eggtimer kit- the one caveat being I'm not likely to be able to include nearly as professional instructions. If you absolutely don't want to assemble anything I would consider building it for you- however, I would charge an additional fee and there would be no guarantee of turnaround time, as I would need to find a solid block of of time to sit down and assemble it.
I'll send out a more comprehensive update once I have a bit more time, but if you have any questions feel free to ask here or via email!
Once the kits are ready I would love to try one, alpha, beta, or prod.Hi again all!

C++ is fine. As far as instructions, I think a bullet list of high level steps will be sufficient. If there are difficult to differentiate parts some guidance/hints will be appreciated.Glad to hear there's interest! @curtisheisey, @anbhtblr, @sooner.boomer, you have been added to the list.
Curtis, the ArdIU does support roll/attitude tracking in theory, but I've been getting some wonky numbers on my test flights- I probably just need to calibrate it, but I'd like to make sure before I say it's officially supported. Would you be writing your own firmware or using some configuration of mine? If you're looking to develop your own, I'm happy to give you the hardware specs so you can start prototyping if you have the parts lying around.
On the subject of firmware, when I get the chance I'll set up a Github repository for this project- the firmware is essentially an Arduino library, so programming the altimeter is done by literally writing a C++ script. However, I'll be happy to publish some basic tweakable configurations for common usage- e.g. logging only, standard dual deploy, etc.
On availability time- I'm going to need to order more PCBs to be able to get all the beta kits together, so it will be a few weeks at least before I'm ready to ship.
How vital are step-by-step assembly instructions to everyone? I can certainly do it but I would need to find some time once PCBs are here to do a fully documented build.
