Toothbrush charger stand Philips Sonicare

I design toothbrush chargers with plastic sockets that are prone to instability. So, I created my own device. It also glows when the toothbrush is charging. To achieve this glow effect, I employ a solenoid with 20 coils made from enamel copper wire extracted from the secondary winding of a small transformer. I also use a round shape rectifier bridge sourced from an old power supply unit that shares the same transformer as the one used for the solenoid. In addition, a capacitor rated at 470uF / 16V, also taken from the old power supply unit, is utilized. Furthermore, four orange 5mm diodes are used to create a glowing effect. To diffuse the light emitted by the diodes, I place a pillow underneath them. The parts for this device were printed separately using an FDM printer. One of these parts was printed in two colors using a Prusa printer and the color-splitting page from Prusaprinters.org. After printing, wires are inserted into the bottom part of the base, and LEDs, capacitors, and other components are soldered onto the board. When soldering, it is crucial to pay attention to the polarity of the rectifier bridge, capacitor, and LEDs, and to ensure all parts are securely glued in place. The device can be easily assembled by simply pushing the stand into the charger socket, and it's ready for use.
