+ As I'm typing this, not one of the original wooden elements of the prototype has survived. Well, prototypes are not + meant to last. In this case, the beamer arm prototype lasted for a single movie sitting before I realised that it was + , on the long run, structurally unstable. More specifically, the single hinge took quite a lot of force. The inside + pin is only 8 centimeters high and combined with the length of the arm, the construction makes for quite a lever. The + top of the hinge started to come off the back-plate, and, more worryingly, the top curl of the hinge started to open. + Back to the drawing board then! +

+ As a reminder, the current mechanism consists of a couple of parts. A single big hinge that connects an MDF arm to the + wall. Then, a circle with two fixed side plates on top. The arm slides in between these plates. Below the circle, the + beamer mount plate is fixed, which can rotate. The whole mechanism would fit in between two shelves in order for + inconspicuous storage of the beamer. +

+ I wanted to save the old hinge, as it was an expensive part.

Now I could carve out a new arm, which would prove less heavy than the original one (partly due + to the cut-outs, partly due to the use of a lighter type of MDF). +
