A wooden table features numerous holes of varying diameters designed to accommodate optical fibers. Due to the size of the ceiling lamp (90 cm x 60 cm), it was not feasible to utilize a single bundle of fibers, resulting...

Ideal for operating 3 to 24V DC existing on-circuit lamps. This circuit was designed to provide continuous light for lamps already wired into a circuit. The circuit is intended to facilitate the operation of existing DC lamps that are integrated...

When the preset is set to its maximum, the LED flashes approximately every half second. This flashing rate can be increased by using a larger capacitor value, for instance, changing from 10µF to 22µF will result in a flashing...

The constant current function module is disabled at the port junction, which has 13 terminals. When the module is turned OFF, the constant current ban port also becomes inactive. The constant current function is lost when the module is...

This circuit can be utilized by individuals, such as a gentleman summoning his butler, a manager calling for his secretary, or, as in the author's case, to call children down for dinner without raising one's voice over the noise...

This design circuit for audio amplifiers with DC coupling to the load is not commonly used today, despite its clear advantages. One advantage is the elimination of the need for a second (symmetric) power supply, and another is the...
