Quad 2 Input CMOS IC 4011 Timer Circuit Timer circuit can be used to switch OFF a particular device after around 35 minutes. The circuit can be used to switch OFF devices like radio, TV, fan, pump etc after a preset time of 35 minutes. Such a circuit can surely save a lot of power. [...]
Today’s computer systems, with their emphasis on high resolution graphics, full motion video, high bandwidth networking, and so on, go far beyond the capabilities of the architecture that ushered in the age of the personal computer in 1982. Modern PC systems demand high performance interconnects that also allow devices to be changed or upgraded with [...]
automatic audio volume control schematic This circuit is used as a series of automatic audio volume control. Audio levels will be in the drive by the voltage of 12 volts 10k ohm resistor connected to the foot differential emitter transistor 2. This series is ideal for users who use the audio volume of digital systems. [...]
It’s a simple metal detector design that has the quite good characteristics. the principle of operation which one differs from the classic schemes (BFO, transmit-receive known as “two-boxes” metal detector, inductive). The dynamic mode is used to find targets in interference environment. There is known from theory of signal filtration that if signal shape is [...]
