Light Following Robot,
By : Chiu Yun Fang
First off, if your new to BEAM and haven't had much experience with electronics, go to Solarbotics and buy the Photopopper 4.2 kit. It is an excellent kit with all the parts you'll need, a high output solarcell, new pager motors, omni-directional feeler switches, in-depth and informative documentation and a cute little PCB. It's well worth the money! Here's a couple pics to wet your appetite


The BEAM photovore is an autonomous robot that is entirely powered by solar ener ....etc

The Lead Acid Battery
Lead-acid batteries, invented in 1859 by French physicist Gaston Planté, are the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, their ability to supply high surge currents means that the cells maintain a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by automobile starter motors.

Nowadays maintenance-free lead-acidbatteries are common in vehicles,inverters, and UPS systems. If thebattery is left in a poor state of charge, itsuseful life is shortened. It also reduces thecapacity and rechargeability of the battery.For older types of batteries, a hygrometercan be used to check the specific gravityof the acid, which, in turn, indicates thecharge condition of the battery. However,you cannot use a hygrometer for sealedtypemaintenance-free batteries. The onlyway to know their charge level is by checkingt ....etc

ABSTRACT
All manufacturing activities necessarily generate some form of waste. The manufacturing process does not consist of hundred percent of conversion of material and energy inputs into usable final products; some portion of the material and energy inputs inevitably ends up wastes. When the waste generated exceeds the maximum assimilative capacity of the environment it becomes pollution. This seminar focuses on LEAN productions, which aims at elimination of wastes there by reducing the environmenta ....etc

There are 3 leads in a transistor viz. collector,emitter and base. When a transistor is to be connected in a circuit,it is necessary to know which terminal is which.
There are three systems in general from which we can determine which terminal is which,they are as follows

Lead and chromium as limiting factors in recycling textile industrial sludge as an amendment in crop production
Abstract
Textile and dyeing industry is one of the leading industries in Tamilnadu state of India. The coagulant process followed for treating the wastewater generated from this industry leads to sludge accumulation with a production of daily average of 10 tonnes in each Common Effluent Treatment Plant (CETP). As the sludge contained 17.2 per cent of Ca, its ameliorative potential as an amendment al ....etc

ABSTRACT


The electronic industry is the world’s largest and fastest growing manufacturing industry in the world. Discarded electronic and electrical equipment with all of their peripherals at the end of life is termed e-waste. The quantity of e-waste generated in developed countries equals 1% of total solidwaste on an average and is expected to grow to 2% by 2010 and i ....etc

AUTOMATIC SPEED CONTROLLER FOR FANS WITH ON/OFF CONTROL BY LIGHT

ABSTRACT
The circuit designed here lets us turn ON/OFF a fan or any device by just directing a torch light or any other light towards its light-dependent resistor. In short we are tiying to develop a remote control for turning ON/OFF an electronic device.

ABSTRACT

Traditionally, input shaping has been used outside the feedback control loop. Utilizing input shaping in this way prevents it from directly addressing some important vibration control issues such as disturbances, nonzero initial conditions, actuator saturation, etc., These potential applications, however, will never be fully exploited unless a good understanding exists of how to create stable CLSS controllers.
