Summary

single axis mechanical sun tracker. Panel points exactly to sun 24/7. Video is of first version. this version is fully 3D printable. (made with MJF) you will just need a few screws and pins for final assembly. This works anywhere on northern hemisphere ( and probably on southern if you reverse orientation). just point base to Northpole and set angle to your latitude. 1 day = 1 turn. you just need to set the Cam disc correctly. highest point on 21 June or lowest point on 21 Dec. you can see the sun shadow through the hole on the head on the small flats.
->Use NewCam-73, somehow I forgot 1 tooth.
