Cheap DIY Power tools SPEED CONTROLLER

How to make a simple speed controller for almost all devices with AC electric motor? It’s easy ! Take these few elements, add some creativity and commitment to it. The regulator enables smooth control of any power tool, it will be useful in every home and especially in every “do it yourself“ workshop! The housing was designed based on a simple electrical box, the socket is a flush-mounted model, and the electronic system is widely available and costs really little. The regulator is able to control a single-phase device with a maximum power not exceeding 2000W, making it perfect for controlling a huge range of power tools. Yes, I know, many power tools have their own regulator built in, but sometimes it’s more convenient to use an external one that can be installed in a convenient place (my column drill needed it for a long time!).
