If you are building or troubleshooting audio circuits, both audio signal injector and audio tracer is important tools. tracing audio signal means tapping a signal at certain point, and check if the signal is exist. Here is the schematic diagram of the signal injector/tracer circuit: Tracing an audio signal can be done using …
Read MoreThis low noise audio power supply circuit can reduces noise and ripple voltage by 40dB over the 100Hz to 20kHz audio range. In portable application such as cellular phones and multimedia notebook computers, a clean source of 5V power for driving audio circuits can be provided by this circuit. Noise up to 1000Hz or so …
Read MoreThis is a circuit of L200 light controller. The output of this circuit is controlled by the surrounding environment’s brightness. If the brightness increases, the output voltage will increases as well. Here is the circuit : The R1 and photoresistor are connected in parallel. They are used as regulator. If we …
Read MoreThis is the simplest circuit that mains powered light bulb to flash. To build this circuit we do not need a much money. This circuit can be used in small parties and similar occasions. This circuit is made by wiring a fluorescent lamp starter and a normal light bulb in series. So the light bulb …
Read MoreThis is a light dimmer circuit. It has no fancy special feature, it is a a quite typical TRIAC based dimmer circuit. This circuit is only used to operate with non-inductive loads like standard light bulbs. Compared with the 120V AC above design, the triggering circuit is little bit improved. Besides that, this circuit is …
Read MoreThis is true subwoofer circuit. This circuit is used for 15- to 18-inch woofers and will not work with 8- or 6- inch “subwoofers.” It has bass-reflex, a good infinite-baffle, or foldedhorn enclosure, and driven by driven by an amplifier with at least 100 watts. This circuit will most useful for home theater applications, which …
