A good portion of money from sales and donations is fed directly back into supporting FPP. This applies in multiple ways including buying hardware to test FPP on such as new Pi/BB/PB versions, providing capes and other hardware to the support team members, and even traveling to shows to teach classes. While creating the DPIPixels output CaptainMurdoch/Chris made extensive use of a USB oscilloscope that was purchased previously when working on creating another FPP Channel Output a few years ago. This isn’t a worthwhile paying job for us, there is no way we will ever get back enough for the literally tens of thousands of hours the team has spent creating and supporting FPP. If we charged a going rate for custom programming to create and support for FPP, the cost of this project would easily have exceeded multiple millions of dollars since we created FPP in 2013.
