Now that the DIY Drones community is more than 20,000 people, we're getting a lot of requests to participate in our various projects. That's terrific and we absolutely love and depend on the work of volunteers here. It's also a fun and rewarding experience for the dev team members: they get to help determine the path of these projects along with inventing new ones, see their contributions used by thousands of people, work with other awesome talents and get all the free hardware they need, along with prototypes of new products.
But it's often hard to figure out exactly what jobs are right for which people, and how to add people to existing teams without causing disruption and slowing everything down with training and communications (the "Mythical Man Month" problem).
We currently have more than 40 core developers working on ArduPlane, ArduCopter, ArduRover, various ground stations and hardware spin offs, along with several dozen other contributors. That's nearly fully staffed, and requires nearly full time coordination of the various mailing lists, code repositories, wikis, Google Docs planning documents and weekly Skype dev chats. But we do want to have a path by which new contributors can join, in a way that slots them in best both for their own interests and skills and the projects' needs. This ensures that we're constantly refreshing the dev teams with new ideas and energy, and taking the load off core developers as the projects expand and life occasionally intrudes.
The best way to participate is to do something cool on your own and share it here. All of our code bases and hardware design files are open. If you see an opportunity to improve something, just do it, post it and then tell the community about what you've done. If it's good, people will use it, help improve it, and we'll get a sense of what you can do. That makes it much easier for us to figure out what your skills are and where you'd fit in best.
So bottom line: see something you think you can improve? Just do it. If it's cool, your reputation here will grow and you'll be much in demand. It's as simple as that.
