Well this is not as cool as the HOTT setup but it does work for a few basic items. I am going to dig around the code some to see if I can unlock a few AQ features. I used the code from this thread and used a arduino teensy 3.1. I guess about any arduino board would work. The only code change I made I changed the baud rate on the mavlink to 115200 so far to make it talk to each other. I just setup wav files to the values from the telemetry.
some of my findings so far.
T1 = GPS Lock(4614=no gps) (4617=2d gps) (4619=3d gps)
T2 = 32=disarmed 34=armed
Cells = Pack Voltage
Cell = Cell voltage (uses pack voltage divided)
Galt = GPS Alt
Fuel = Status (1=standing by) (2=active) (4=pos hold)
Lat & Long works with no adjustments
Here is a quick demo video
