The OrbShield is an open project managed via the Sourceforge.net site.
We do accept donations to promote further development, blunt the cost of prototyping, and acquire more hardware for testing and development. If you are interested in donating to the OrbShield project, you may donate at the SourceForge site here.
Note: From time to time the developers will build OrbShield boards and sell them for a nominal fee (basically parts plus a small amount for soldering labor) for those who feel unable to build/buy a board and assemble it themselves. While we feel this is an acceptable thing to do under the name of “donations”, if you feel uncomfortable donating via the SourceForge site, you may certainly approach the developers directly and we will try to accommodate, time and effort permitting.
