I’m calling it OpenChrony. It’s an open source chronograph, compatible with nerf and paintball. It is Arduino-based, and the code is publicly available, as are the part files (.stl, .step and .sldpart coming soon). I’m hoping that others will improve the design, this is only the first functional version.
