This is a current work in progress, but it's good enough to take up in the air and do some testing. I want to get nice completely vertical photos that I can stitch together to make aerial maps. This 2 axis downward gimbal is something I designed and will be testing in the air soon. Once I get something that works well I will be sharing all of the design files. I'm currently using a SimpleBGC board with AlexMos firmware.
