This afternoon I was able to get the correct combination of software, drivers, and cables to update the firmware on the Dynons. The D100 had been in service before, so it was only a few versions old. The D180 was factory new, and the firmware was very old. I also updated the HS34. Then I cleaned out the paint booth and taped the horizontal tail pieces for blue paint. I sprayed those in blue, cleaned the gun, and left after dark again. Some of these paint nights tend to run pretty late.
