It's been a long time since an update! A LOT of work has been done on both the board hardware and the flight software since the last update.
First, the hardware. We're tantalizingly close to pulling the trigger with our manufacturer on production of the finished-product board. We have three systems to fully test before the production starts: the EEPROM, the SD card reader, and the sound channel. An upgrade on the board is the addition of the MS5611 pressure sensor alongside the existing BMP085 sensor. The dual sensor capability increases flexibility of the board for a wider range of flight controller applications.
Second, the flight software. A lot of changes have been made to our version of the AQ32plus code (some of it is already available at github.com/ashima/AQ32Plus ). We've completed major upgrades to the flight stabilization, added much improved state estimation from the pressure sensor and from an external GPS, and added height and GPS holds. We've added WiFi control to the code, and additional telemetry for debugging and flight logging. These components are still undergoing testing, but will be open-sourced as with our prior "Ashima" versions of the AQ32Plus flight software.
Thanks for hanging in there with us as we are now way past our original target date. Much of that schedule slip has been due to a making sure you have the best flying experience, which meant software changes that need to be tested. We originally conceived the project as primarily hardware development - but as we moved forward, we increasingly realized we wanted the flight software to do more and do it better. We believe we're now looking at a shipping date early in the new year, but we will be able to firm this up better as we check off the deliverable milestones with our manufacturer.
Thanks again for your support and ultimately we think you guys are going to be very happy with the resulting flight system!
