Hello, I was in Finnish tank-army with T-54 and T-55 tanks, and now I'll try to get T-90 moving and shooting like real.
It is not easy, but let's try.
The mecanical bilding is near finnish, and now I am making the shooting and aiming more real.
First laser aiming with FPV driving, and shooting, with Arduino stabilizing for barrel and traverse, but it takes a little time.
If somebody has played with Arduino, I'm hearing any advice.

Later on I am adding some pictures of my project.

This evening I started to move the main switch from the bottom to backside of T-90 to make easier use the main switch.
