I feel like this is a huge loss, not only for astronomers, but for how we feel about ourselves in this world ---Great and lost feeling. To be honest, though, given all the other issues that the country is dealing with, it seems a hard sale to get people very interested in over-lighting when lighting costs are lacking in connection with the night sky.
I also connected a 2. The charger for this type of battery has 5mm male audio plugs that allow me to charge the battery without taking apart the model, which is basically impossible. The VIP snake has a small button switch in its nose that allows lighting to be turned on and off using a pencil or screwdriver, but is basically invisible unless you know where to look.
The only moving part is the rotor, which contains the magnet. When things get complicated, the order of the excitation winding is arranged. The polarity of each winding is controlled by the current direction. The animation demonstrates the simple mode that the controller will follow. The alternating current changes the polarity, giving each winding a \"push/pull\" effect.
