contactless digital tachometer using 8051 abstract

Contactless digital tachometer using 8051.
A three digit contact less digital tachometer using 8051 microcontroller which can be used for measuring the revolutions/second of a rotating wheel, disc, shaft or anything like that is introduced in this project. The tachometer can measure up to a maximum of 255 rev/sec at an accuracy of 1 rev/sec. What you just need to do is to align the sensor close to the reflective strip (aluminium foil, white paper or some thing like that) glued on the rotatin ....etc

LASER TORCH BASED VOICE TRANSMITTER AND RECEIVER
Using this circuit you can communicate with your neighbors wirelessly. Instead of RF signals, light from a laser torch is used as the carrier in the circuit. The laser torch can transmit light up to a distance of about 500 meters. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch. If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. The transmitter circuit (Fig. 1) comprises c ....etc

ABSTRACT

Using this circuit you can communicate with your neighbours wirelessly. Infrared signals are used as the carrier in the circuit. The infrared signals can transmit up to a distance of about 5 meters. The phototransistor of the receiver must be accurately oriented towards the IR beam. If there is any obstruction in the path of the IR beam, no sound will be heard from the receiver.

This intelligent switch circuit enables automatic, switching on of an emergency light system during darkness in the event of mains failure. The mains power failure condition is detected by the section consisting of mains step-down transformer X1 followed by bridge rectifier comprising diodes D1 through D4 and smoothing capacitor C1. If the mains is available then it causes energisation of relay RL1 which has two sets of changeover contacts. The light/darkness condition is detected by the circuit comprising phototransistor FP ....etc

Hi,
I'm doing a project on Power quality improvement in transmission line using D-statcom.

This paper presents the enhancement of voltage sags,
harmonic distortion and low power factor using Distribution
Static Compensator (D-STATCOM) with LCL Passive Filter in
distribution system. The model is based on the Voltage Source
Converter (VSC) principle. The D-STATCOM injects a current
into the system to mitigate the voltage sags.LCL Passive Filter
was then added to D-STATCOM to improve harmonic distortion
and low power factor.

I'm n ....etc

This seminar includes the theory, design and construction of a haptic display for creating texture sensations through variations in surface friction. Ultra sonic frequency, low amplitude vibrations between two flat plates have been shown to create a squeeze film of air between the two plate surfaces thereby reducing the friction. Here, it is shown that a reduction of friction will also occur between a human finger and a vibrating plate. Thus, a vibrating plate can serve as a haptic interface. The amplitude of vibration can also be correlated to ....etc
