	Reseña
	The word psychedelic, used by the author in Chapter 1 pertains to a state of relaxation and pleasure with heightened perception. Such relaxation and pleasure can be experienced by observing various patterns of coloured lights In the good old days, mechanical devices using rotating discs or drums used to be employed to produce various patterns of light effects Such psychedelic light effects are known as DISCO. In modern projects, Disco affects are provided by digital electronics The present book written by Mr M C Sharma is all about these projects You will find them both fascinating and instructive.
La psicodélica palabra, utilizada por el autor en el capítulo 1 se refiere a un estado de relajación y placer con mayor percepción. Tal flexibilidad y placer puede ser experimentado por la observación de diversos patrones de luces de colores en los buenos tiempos, los dispositivos mecánicos que utilizan discos giratorios o de los tambores utilizados para ser empleados para producir diversos patrones de efectos de luz Tales efectos psicodélicos de luz que se conoce como DISCO. En los proyectos modernos, Disco afecta son proporcionados por la electrónica digital El presente libro escrito por el Sr. MC Sharma es todo acerca de estos proyectos en los que va a encontrar a la vez fascinante e instructivo.

	Reseña
	As far as we are aware, there is no book in the market which provides a large number of practical projects using only one type of CMOS IC. The author has selected CD4011 for his projects. CMOS is a versatile device and the IC CD4011 can be put to many applications. It is the basic building block chip consisting of four NAND gates and is more versatile than the CMOS IC 74. As you can see from the contents, the IC can be used as linear amplifiers, multivibrators, schmitt triggers, pulse generators, and crystal oscillators. Besides, fascinating projects such as light flashers, blinkers, metronones burglar alarms and a host of other projects can be built out of this single IC employing only a few external components. We hope that our readers will enjoy building these projects and find them useful as well.

103 Projects Using LED's

	103 Projects Using LED's T.R. Mishra BPB
	Reseña
	Electroluminescent semiconductor devices are assuming a great importance in electronic world. There are now many devices related to this family. The electroluminescent panels, laser diode, infra red diode, light emitting diode (LED) and LED Displays are some of the important members of this family. The electroluminescence is a phenomenon occurring when a semiconductor material emits light under the influence of electric field. We are concerned here with the LEDs and the LED Displays which are now increasingly used by the equipment manufacturers. The LEDs have very wide variety of applications, especially in read-out circuits and indicators. They are now used where fast and low power devices of the greatest possible life—10, 000 to 10, 00, 000 hours—are required.
Los dispositivos electroluminiscentes de semiconductores están asumiendo una gran importancia en el mundo de la electrónica. Ahora hay muchos dispositivos relacionados con esta familia. Los paneles electroluminiscentes, diodo láser, diodos infrarrojos, diodos emisores de luz (LED) y Displays LED son algunos de los importantes miembros de esta familia. La electroluminiscencia es un fenómeno que ocurre cuando un material semiconductor emite luz bajo la influencia del campo eléctrico. Nos ocupamos aquí de los LED y las pantallas de LED, que son cada vez más utilizados por los fabricantes de equipos. Los LEDs tienen muy amplia variedad de aplicaciones, especialmente en lectura fuera circuitos e indicadores. Ahora se usan en dispositivos de potencia rápidos y de bajo del mayor número posible de la vida-10000 a 1000000 horas son requeridos.
