Stereoscopic rotating musical Christmas tree DIY kit seven colours LED electronic soldering practice loose parts

Product model: TJ-56-499

Working voltage: DC5V

Product Introduction
DC 5V, powered by DC5 power holder, positive inside and negative outside. The circuit is mainly composed of wireless power supply board, wireless reception board and two Christmas tree circuit boards. The wireless power supply part is mainly composed of a NE555 oscillation circuit to output a square wave signal of about 50 kHz to drive the field effect transistor IRF530. The primary coil, the secondary coil on the receiving board and the magnetic ring form a switch transformer. The primary coil is controlled by a field-effect tube to generate a high-speed alternating magnetic field, so that the secondary coil can sense alternating current, which is supplied to the three-dimensional Christmas tree after full-wave rectification.
