What to do if you want to help out on this project
Right now, this project is stalled until I finish the GunFire alpha. If anyone really wants to work on the hardware, I'd be quite happy to pass across my current ideas for the design. With just me on it, it's going to be some time before the design is done, and longer still until it's been tested, firmware has been written, and the whole thing's ready for people to build. So if someone else fancies taking the lead role on GunProg, feel free!
I haven't yet set up the SourceForge forums so that people can post suggestions. This will happen at some point in the near future. Until then, you can contact me via SourceForge on the link above.
