Thank you Guys.
I got some ideas brewing, and one of them is allready under planning.
A large diorama with funktions. Main centerpiece will be the ModellCollect Austrätt Fort kit.
So we are talking a diorama showcasing Battery Oerlandet in Norway 1944.
Diorama will be around 120x70cm.
My plan is to make the gun turret traverse and barrels elevated and lowered by turning some potentiometers, connected to a Arduino board and servos.
Surrounding bunkers and housing will have light installed, and parts of the main gun bunker will be displayed as cut-thrue feature.
Or, that is what i Hope to do :D
