Smart lock v2

That is a second iteration of my entrance gate lock. First iteration used electric gear motor to move the reel. Unfortunately gearbox of that motors lasts for about 150 cycles and then breaks. So i decided to play with pneumatic cylinder.

Mechanically that new version much simpler. Now it's just a box that hides end stop magnetic reed switches and holds mechanical lock cylinder.
Electronics, small air pump, pressure tank and valves moved out to dedicated box.
