axium cinema camera is open source, really interesting. open source headphones (2 brands found), some open source beehive stuff, an open source village startup project featuring open source designs of devices to help startup a civillization out of nothing, and some microboard thing, arduino like but more open source. all hardware physical cable standards are open source in the sense of knowing what they look like and are made of,

but regarding computers there isnt much choice indeed... there is some wiphone project for a simple dumbphone like experience tho.
