well ... one thing i am about to do is finish the pendant design and upload the 3dcad files and some toolpaths for it. i have designed it into a 10x7x1.5" product. i need to get the thing machined first, to see if its worth using for anything.. i also have a simple 6axis hobby-servo driven robot arm that i think would be really nice if cut from graphite or lexan or something. its a solidworks file right now. it can be see at:
