I'm an entrepreneur and engineer, currently working on a project that requires thin tension hinges, and I noticed some hinges that I liked in the mount system on Microsoft Lifecam webcams, particularly the Lifecam 3000. I don't know who at Microsoft can tell me how those hinges were acquired or sourced. No hardware or production company has been able to find a tension hinge so thin. Please let me know of any questions or concerns. I have photos of the exposed hinge itself if that helps.
