For a long time did not work straight on a project, completed the weapons in 4 days or so. I worked with materials and, let's say, the General concept. Over the light was not working so I know that's not it, but the project's goal was different - to learn to work with materials. So I would ask you to leave a review about the materials and the General concept of weapons: what you don't like, where to correct, etc. I will attach this thing to the future robot, but there is still far away)
