LED lights powered by a single battery have been available for quite some time. I believed we could discover an appropriate circuit and replace candles with a few LEDs instead.
Designed the PCB using Surface Mount Device (SMD) technology to minimize space usage, although working with SMD components was challenging due to their smaller size. I had to use a magnifying glass during installation, and without it, completing the task would have been impossible. Additionally, to secure the PCB in place, I attached tape on both sides while soldering. This prevented constant movement, ensuring stability during the assembly process.
LED DC-DC CONVERTER SCHEMATIC
A blocking oscillator is described as a functioning circuit. The charging coil chosen is cost-effective, and the resistance type is selected to minimize space usage. However, the LED turns off after approximately 10 seconds.
Upon measuring the current passing through the coil, it was noted that it reached 300mA. Regrettably, the bobbins with resistance-type windings did not fit the requirements, and the wire around which they were wrapped was rather thin. Substituting with a 100uH coil from ATX power supplies, presumably from the -12V channel, proved to be successful.
An electronic oscillator is a circuit that generates a periodic oscillating electronic signal, commonly in the form of a sine wave, square wave, or triangle wave. These devices transform direct current from a power supply into an alternating current signal.
Oscillators, whether mechanical or electronic, function based on the principle of oscillation, involving a regular fluctuation between two states driven by changes in energy. Various devices such as computers, clocks, watches, radios, and metal detectors utilize oscillators.
Oscillators are cost-effective, making them budget-friendly options. Portable: They use a direct current source to convert unidirectional current into bidirectional current, eliminating the need for any moving components to generate energy.
