The Hexenbiest DiY open source project is an Arduino shield for a FPV ground station. It has A/V ports for up to six video receivers, OSD (on screen display) for menus and telemetry data, several user interface control methods (IR, R/C, Joystick), multiple video outputs, support for an external camera / mic, and more. I will post the hardware design (schematics and BOM) and offer technical advice. I even have a small number of unpopulated PC boards (without components) I can offer at low cost to help move things along. But due to their limited number these are reserved for rc-cam members that have the skills to solder the SMD components and are serious about contributing code to help launch the project. UPDATE: See this post for hardware design docs: http://www.rc-cam.com/forum/index.php?/topic/4018-hexenbiest-open-source-antenna-tracker-ground-station-osd-project/?p=28022 Just to be clear, this is a hardware design that is begging for software. I'm here to drum up some excitement and invite creative programmers to help build their dream FPV ground station in the spirit of open source sharing. But this won't happen without software (and hardware) contributions from like-minded hobbyists. The project is called Hexenbiest. It is configured as a plug-in motherboard "shield" for an Arduino MEGA2560-R3 microprocessor board. Sorry to disappoint that it doesn't use a BeagleBone, Rasberry Pi, or other high-end CPU. The Arduino was chosen because of the huge community expertise and bargain price. But of course you are free to use this project to create your own hardware variant using the CPU you want. After all, this will be an open source project. Here is a photo of the assembled board (click it for larger view). Project background (skip to next post if you hate infomercials): The number of DiY open source projects for R/C and FPV is staggering. Some are software variants for popular open source hardware platforms (i.e., minimOSD). Just as brilliant are those super-charged firmware upgrades that turn low cost devices into magnificent performers (i.e., OpenTX). From my observation many got their start by the availability of some interesting low cost hardware; The software developers recognized the potential of doing something big with the hardware and went to work. Fantastic open source communities have been created this way. We can do that too! Over the years I've dreamed of a flexible hardware platform for a FPV ground station that would be substantially software driven. The common theme in this vision has always involved multiple FPV receivers and OSD features. The idea is to push most of the functionality into the software and minimize the hardware the user would have to build. The reason for this is there are a lot more experienced programmers out there than hardware designers. And best of all, popular open source projects attract the attention of the Chinese cloners; Cheap software-ready hardware is eventually sold to us hobbyists; Then it's all about the software and there is no need to build anything!
