David and Ryan are the two engineers/tinkerers behind Eclectical Engineering, which they formed as a means to showcase their experimental projects. Their inaugaral project involved firing a GoPro camera out of a homemade pneumatic cannon, all on a budget of $150. 3D printing played a helpful role in the process - a 3D printed, aerodynamic capsule provided the stability and protection the camera needed for a safe flight and landing. Watch the video of their experiment, and, if you'd like to try it yourself, Eclectical Engineering has provided full instructions for replicating the project.
