Простейшая Пищалка Поисковик для квадрокоптера своими руками

Good day to all! I think those who have ever lost their quadrocopter will understand why you need a search engine squeaker. And these people, probably 99%. I have a quadcopter budget - it's a x8hg sim. On it and I will conduct experiments. Tweeter search engine can be done in half an hour and spend on all less than 70 rubles. It starts to squeak at the moment the console signal is lost, when the battery is discharged and when turned on, i.e. when the LED lights blink. Such a device can be connected to almost any quadcopter, but of course, this will be especially important for owners of low-cost devices, because they have no GPS, no return home, etc. functions. The scheme was not invented by me, taking the opportunity, I express my deep gratitude to the developer, THANK YOU VERY MUCH! This scheme is available in almost every forum about quadrocopters, but for some reason no one else has shown how to assemble it, because not all of us can read even such simple schemes and not everyone can solder. This squeaker can be assembled even without a soldering iron, by twisting the long legs of the parts and their subsequent crimping with small pliers, the wires can be screwed to the existing backlight, and the ground wire can be screwed to the minus wire of the board that goes to the battery. So, if you do not own a soldering iron, it should not stop you, but still it is better to contact a friend with such a tool. Good luck to everyone, great flights for you and no loss).
