Here is a Tv remote jammer circuit, using NE555 timer IC. By using this you can watch your favorite TV channel without any interruptions. Ie; No one can be able to change the channel by means of remote, if the circuit remains ON. The circuit is simple to make at your own home, with very low cost.  Let’s go deeply into the specification and requirements of this Project. Read More.....

Here i am going to present you a simple Emergency Light circuit diagram using 2 white Leds. Leds are convenient, cheap, cool and having long life. In this circuit we are using 2 Leds (white is prefered) to increase the brightness. The heart of this circuit consists of IC HEF 4093. The circuit is powered by a 9V battery.

In clamper circuits a predetermined dc level is added to the output voltage. In other words, the output is clamped to a desired dc level. If the clamped dc level is Positive, the clamper is a POSITIVE CLAMPER. On the other hand, if the clamped dc level is negative, the clamper is called a NEGATIVE CLAMPER. Other equivalent terms used for clamper are dc inserter or restorer. Recall that op amps are designed to operate from a single power supply, such as the 124 series, employ a dc insertion technique. The inverting operational amplifier (op amp) that use this technique is shown in the circuit diagram. The value of the capacitors in these circuits depends on the different input rates and pulse widths. It is also noticed that the output waveforms have an added dc level, which is approximately equal to Vcc/2. This fixed positive dc level is needed to obtain a maximum undistorted symmetrical sine wave. The output voltage of the peak clamper is a net result of ac and dc input voltages applie...

Ne555   is one of the most commonly used timer IC. It is a monolithic timing circuit that can produce accurate and highly stable time delays or oscillations. Like general purpose OP AMPs, it is very much reliable, easy to use and cheaper in cost. It has a variety of applications including monostable and astable multivibrators, dc-dc converters, digital logic probes, waveform generators, analog frequency meters, tachometers, temperature measurement and voltage regulators. The timer basically operates on one of the two modes either as a monostable or as an astable multivibrator. Read More.....
