The simplest scheme. Everyone needs it. In every house. Anyone can do it. The main thing is to know which side to hold the soldering iron. This device is used for different tasks. Fan speed controller. Dimmer for LED strip. Voltage regulator. Engine speed control. It is perfectly suitable for mini drilling machines, mini sawing machines, engraving devices and other electromechanical devices operating from constant voltage. Only two cheap parts are required for manufacturing: A variable resistor with a resistance of 10 kOhm and a field-effect transistor. I used IRFZ44N. There are no complete analogues for it, but there are very similar in their technical characteristics and description. These include IRFZ44E, IRFZ45, IRFZ46N, IRFZ40, BUZ102, STP45NF06, IRLZ44Z, HUF75329P3, IRF3205. There are also Russian analogues: KP723 and KP812A1. The maximum allowable crystal temperature according to the reference books is slightly less (up to 150 °C). But it is worth considering that Russian manufacturers have always indicated the operating parameters, and foreign ones - the parameters at which the part fails. For example, the optimal operating temperature for IRFZ44N is 75-100 degrees. At the same time, the maximum allowable power in reality is reduced by half. Keep this in mind when building a circuit. Use radiators.
