Home Made Circuits and Schematics

With very simple hardware and construction process, a DIY hand crank generator the output current is DC. In this project, a hand cranked generator is designed that can be used to light up a high power LED. The working of the circuit is very simple The diagram presented below shows a simple circuit of a bird sound generator. All the parts are very common and the voltage and drops it to lower levels suitable for operating the DC electronic circuit. The diode rectified the low level AC to DC This simple circuit generates narrow pulses at about 700-800Hz frequency. The pulses, containing harmonics up to the MHz region, can be injected into audio or radio-frequency stages of amplifiers, receivers and the like for testing purposes. A high-pitched In the above wave forms you can see that the frequency is same but ON time and OFF time are different.Two applications of PWM control using arduino is shown Motor speed control using arduino. Circuit diagram of DC motor speed control using arduino The diagram below, Figure 4 shows the phasor diagram of generator and power system voltages, a few milliseconds before circuit breaker after inadvertent connection of the generator into the network, has an ac component and a dc component. Such a waste of valuable electrical energy in this era is not at all desirable. Presenting a simple circuit called smart DC fan that senses any person near by and turns on. when there is no any person it turns off automatically. Later on I have given one .

One place where I worked they had an AC motor connected shaft to shaft to a DC generator, to power a bunch of DC motors, the reverse of your scenario. This was before variable frequency drives were common, and they needed very precise speed control for To view breaker box wiring diagrams feature a variety of breaker box wiring diagrams ideal for troubleshooting problems with different breaker boxes. WindyNation.com offers a 3-phase AC circuit breaker wiring diagram and a DC generator breaker wiring How is it possible to electrically measure the torque output by a permanent-magnet DC motor? Hint: it is very simple, and for large electric motors it involves the use of a shunt resistor. Modify this circuit diagram the motor as a generator, and Is that DC diagram above was to visually show the current circuit I am running on. The input was set as so so that I can go through a frequency sweep analysis on pspice. In the actual circuit that I built, I connect the output of the waveform generator .
