About two years on my backpack 2 processors in a socket dangles. Now you can make one more keychain. Just a photo. For the manufacture on the base of 478 sockets, a 1mm drill is required, since The key on the processor is not symmetrical. Socket 7 is easier. Well, 2mm drill to attach the ring. Some more photos of the manufacturing process in my blog. The link can be found in my info, if interested. 2 processors are inserted into the socket from different sides: Photos from the old man: Just on the latch processors are kept bad, one, the one below, will need to be glued. The top one can be removed at any time by opening the socket.
