Nice labels on a home budget

[jdurand]

On that last one you'll see the label on the side and the end panel is a piece of clear acrylic machined to >just< fit inside the aluminum tube and has holes for 3 LEDs, connectors, and access to DIP switches.

This was the first one, after this they were black powder coated (using an official Craig's List toaster oven to bake the paint).

Behind the PC board is a motor and coupling arrangement mounted on a bracket made from a piece of aluminum channel mounted to conveniently hide the mechanism.
