In the video, a person is seen holding a small electronic device in their hand. The device appears to be a circuit board with various components attached to it. The person is using a soldering iron to connect wires to the board. The soldering iron is being used to melt solder and create a connection between the wires and the board. The person's hand is steady as they carefully apply the solder to the connection points. The background of the video is blurred, but it appears to be a workshop or a similar setting.
