Ever wonder how a touch plate, like the kind you see on some elevators and lamps work? This circuit will give you a feel for how the touch plate works in a circuit and you can expand on the circuit to suit your project needs. The touch plate can be a small piece of metal or aluminum foil. Start the circuit by moving S2 to the set position and then back to the previous position. Now press S1.

In most WCs with an extractor the fan is connected to the lighting circuit and is switched on and off either in sympathy with the light or with a short delay. Since toilets are sometimes used for washing the hands or just for a quick look in the mirror, it is not always necessary to change the air in the smallest room in the house. The following circuit automatically determines whether there

Description:This is a compact three transistor, regenerative receiver with fixed feedback. It is similar in principle to the ZN414 radio IC which is now no longer available. The design is simple and sensitivity and selectivity of the receiver are good.Circuit diagramNotes:All general purpose transistors should work in this circuit, I used three BC109C transistors in my prototype.The tuned

DC motor failures are commonly experienced by many of the users, especially in places where the relevant motor is run for many hours a day. Replacing motor parts or the motor itself after a failure can be pretty costly affair, something which nobody appreciates. A request from one of my followers was made to me regarding solving the above issue, lets hear it from Mr.Gbenga Oyebanji, alias Big
One of the innovative methods of generating modified sine pulses designed by me, was built and tested by Mr. Ali Rexhepi, lets learn how he went about the entire procedure. Before that first have a look at the circuit diagram which was invented and designed by me.
Swagatam here are those screen shots .Theres four pics,
two of the wave forms PWM at 59.760 Hz are at diode junctions IC1
Since you say that with my PWM circuit the current consumption of the inverter shoots to a dangerous 14Amps, therefore I just thought, probably we can solve this by reducing the drive voltage to the gates of the mosfets.
This can be simply done by controlling the base voltage of the buffer transistors. And that is exactly what we are trying to do by connecting a variable resistor
The next circuit shows the IC 741 being wired up for providing a regulated power supply with an output which can be varied as per ones own requirement.
Basically the IC is configured as a comparator cum driver for the proposed power delivering purpose. The employed zener diode has been included for fixing the non inverting of the IC with a constant refernce voltage.
An additional transistor
The circuit diagram shows a simple set up using the IC LM 338 which has been configured in its standard regulated power supply mode.
The specialty of the design is that it incorporates a current control feature also.
It means that, if the current tends to increase at the input, which might normally take place when the sun ray intensity increases proportionately, the voltage of the charger

This circuit arose from the need of the author to provide a 5 V output from the 24 V battery of a solar powered genera-tor. Although solar power is essentially free it is important not to be wasteful especially for small installations; if the battery runs flat at midnight you’ve got a long wait before the sun comes up again. The basic requirement was to make an efficient step-down

For the a one amplifier circuit is very suitable for use in applications subwoofer speaker, which allows for higher spending enough bass. Although output was spent not high, but for bass sounds do not undoubtedly. Indeed, the output is only 20W mono amplifier with 8 ohm impedance. With a maximum supply 44Volt DC.Part listR1 = 47RR2 = 100KR3 = 1R 2WC1 = 2.2uFC2 = 220uFC3 = 100uFC4 = 47uFC5 =

This circuit shows how a 4017 CMOS decade counter can be used to build a timer circuit. Push-button S1 will discharge capacitor C1 through resistor R2. When S1 is released, C1 will charge up through R1 causing a rising edge at the clock input of IC1. This causes the output Q1 to go high (to the supply voltage). Current will flow through R4 and LED D2 will light. At the same time C2 will begin

This is a series of audio amplifier using ic and equipped with a mute switch. This circuit using ic and has 20W output impedance 4 ohms. Scheme and a list of components can be seen below.Part List :Resistor R1 = 3.3KR2 = 39RR3 = 39RR4 = 3.3KR5 = 3RR6 = 3RCapacitor C1 = 1uFC2 = 1uFC3 = 10uFC4 = 100uFC5 = 100uFC6 = 220uFC7 = 0.1uFC8 = 0.1uFIC IC = ULN3793W
