Please let me know how much interest there might be in this device as I am current trying to figure out if I should market it and for how much. I have 3 made already and 6 more on the way.
I'm interested, depending on the eventual feature set. I have Dynon EFIS, Grand Rapids EIS and GNS430. But, depending on what type of testing I am doing I want to be able to select other sample rates - up to 4 samples per second.
I also have an event marker - a momentary switch on the stick sends voltage to pin 1 of a serial port, which is picked up by software as Carrier Detect. I've got provisions for up to three more discretes, using pins 6, 8 & 9.
I've been playing around with recording raw GPS data from an Antaris LEA-4T GPS, in the hope of getting sub-metre accuracy with post-processing, using corrected satellite orbits. But while this works nicely with $10,000 survey-quality GPS units, my initial testing with a $400 GPS has been disappointing. Too much noise in the data. I've got a couple of more troubleshooting steps to take, but I'm not optimistic.
I may also acquire a $100 LabJack U3 to record analog inputs (flight control positions, thermocouple temperatures, etc), but this is a USB device, so it wouldn't be compatible with your current hardware.
At the moment I am planning to record all this stuff using a laptop, with a custom Python script to take care of time syncing the data. But replacing the heavy laptop with a light box is tempting. What software does the controller on the card use? I doubt you want to write software for my very unique requirements, but maybe I would purchase the hardware, and write my own software.
