Heart Lamp with Flashes 18 LEDs Circuit This activity flashes 18 LEDs at three altered ante and you can use these to actualize an clear Valentine Heart. The ambit is kept simple (and low cost) by application the 4060B IC which is a adverse and oscillator (clock) in one package. The ambit requires a 9V [...]

Zener Controlled Transistor Voltage Regulators By john The efficiency of Zener regulated power supply becomes very low when the load current is high. Under such conditions a Zener controlled transistor is always used for maintaining output voltage constant. Basically there are two types of Zener controlled transistor voltage regulators. They are Series Voltage Regulators Shunt [...]
Figure 1. Block diagram of a compact disc player. The bunched disc amateur contains two capital subsystems: the audio abstracts processing arrangement and the servo/control system. The servo, control, and affectation arrangement arrange the automated operation of the amateur and accommodate such items as the arbor motor, auto-tracking, lens focus, and the user interface. The [...]
Lightning Detector Circuit and schematic This Do-it-yourself lightning detector circuit can be a especially sensitive static electricity detector which can supply an early warning of approaching storms from inter-cloud discharge properly prior to an earth-to-sky return strike takes location. An aerial (antenna) formed of the brief duration of wire detects storms inside a two mile [...]
Figure 1. Substituting the diode-capacitor network shown for an inductor allows this switching-regulator IC to deliver 2mA at comparable line and load regulation, with somewhat reduced efficiency. Figure 2. Introducing a MOS driver (IC2) enables the Figure 1 circuit to deliver as much as 20mA. In conventional applications, switching-regulator ICs regulate VOUT by controlling the [...]
