For quite a while I'm using my cell phone as a magnifier glass. So came up with the idea to integrate it into a third hand soldering station. The variable magnification is really helpful when working with SMD components and inspecting solder joints.
The App has an option for manual focus which is really great because the focus will be fixed when you are moving tools during soldering. If your phone has a LED flash it can be used light up the working area.
