AGRICULTURAL ROBOTS

An agricultural robot or agribot is a robot deployed for agricultural purposes. The main area of application of robots in agriculture is at the harvesting stage. Fruit picking robots, driverless tractor / sprayer, and sheep shearing robots are designed to replace human labour. The agricultural industry is

BLOOM ENERGY SERVER

            

                      The Bloom Energy Server (the Bloom Box) is a solid oxide fuel cell (SOFC) made by Bloom Energy, of Sunnyvale,

California, that can use a wide variety of inputs (including liquid or gaseous
hydrocarbons produced from biological sources) to generate electricity on the site

where it will be used. It can withstand temperatures of up to 1,800 °F (980 °C), that would cause
many other fuel cells to break down or require maintenance. According to the company, a single cell (one 100 mm × 100 mm metal alloy plate between two ceramic layers) generates 25 watts.

Bloom stated that two hundred servers have been deployed in California for corporations including eBay, Google, Yahoo, and Wal-Mart.

COMPONENTS
                    The Bloom Energy Server uses thin white ceramic plates (100 × 100 mm) that are made from components found in beach sand. Each plate is coated with a green nickel oxide-based ink on one side, forming the anode, and another black (probably Lanthanum strontium

manganite) ink on the cathode side.According to the San Jose Mercury News, "Bloom's secret technology apparently lies in the proprietary green ink that acts as the anode and the black ink that acts as the cathode..." but in fact these materials are widely known in the field of SOFCs. Wired reported that the secret ingredient may be yttria-stabilized zirconia based upon US patent that was granted to Bloom in 2009; but this material is also one of the most common electrolyte materials in the field. US patent 20080261099, assigned to Bloom Energy Corporation, says that the "electrolyte includes yttria stabilized zirconia and a scandia-stabilized zirconia, such as a scandia ceria stabilized zirconia". ScSZ has a higher conductivity than YSZ at lower temperatures, which provides greater efficiency and higher reliability when used as an electrolyte. Scandia is scandium oxide  which is a transition metal oxide that costs between US$1,400 and US$2,000 per kilogram in 99.9% pure form. Current annual world wide production of scandium is less than 2,000 kilograms. Most of the 5,000 kilograms used annually is sourced from Soviet era stockpiles.

To save money, the Bloom Energy Server uses inexpensive metal alloy plates for electric conductance between the two ceramic fast ion conductor plates. In competing lower temperature fuel cells, platinum is required at the cathode.

                                    stealth fighter

                      

The article How Radar Works talks about the basic principles of a radar system. The idea is for the radar antenna to send out a burst of radio energy, which is then reflected back by any object it happens to encounter. The radar antenna measures the time it takes for the reflection to arrive, and with that information can tell how far away the object is.

The metal body of anairplane is very good at reflecting radar signals, and this makes it easy to find and track airplanes with radar equipment.

The goal of stealth technology is to make an airplane invisible to radar. There are two different ways to create invisibility:

• The airplane can be shaped so that any radar signals it reflects are

                                  Making a Cell Phone Controlled Remote Bell Circuit

The following circuit of a cell phone controlled remote bell can be used for ringing bells or alarm devices using your personal cell phone. The unit incorporates an attached cheap cell phone as the modem for executing the proposed functions.


The explained circuit can be used in schools for ringing bells using a cell phone from anywhere irrespective of the distance. Thus the use of this type of cell phone controlled remote bell can eliminate the need of running for the bell switch on every class period intervals.

The peon would be able to do his other scheduled work and ring the bell from any position inside the school premise or even from outside, in fact from any corner of the world.

Looking at the circuit diagram, we see a pretty straightforward configuration using only transistors.

Make this Wireless Speaker Circuit

Make this Wireless Speaker Circuit- Make Your Own Radio Station Science Project


The article explains a very simple circuit of a wireless speaker system which can be used for playing hi quality music wirelessly from your TV set, DVD player, Ipod, cell phone or from any music system. 
The speaker thus can be placed in any corner of the house within a radial distance of 50 meters and high quality music can be enjoyed without the hassles of long connecting wires.

For implementing the entire wireless speaker system, we actually need to make two sets of circuits, atransmitter circuit for transmitting the music signal from the source input as discussed above and a receiver circuit for receiving the transmitted music signal and for playing it in the attached speaker.

Transmitter Circuit:

As shown in the figure, the configuration looks a little different from the usual single transistor transmittercircuits where a single stage is used for the audio amplification and for the generation of the modulated carrier waves.

Simple Walkie Talkie Circuit

                       simple walkie talkie circuit  



The article explains a simple walkie talkie circuit that can be easily built by any hobbyist and used for communicating between rooms or floors or simply for having some fun across neighbors and friends. The range of this system is around 30 meters. 


The figure shows a four stage transistorized circuit which behaves both like a transmitter and a receiver unit, making the design very economical and versatile. An ordinary “4-pole double throw” switch serves the purpose well for transforming the unit either to a transmitter or a receiver while communicating with another identical transmitter/receiver set. 

As can be seen in the diagram three transistors are directly coupled for making an audio amplifier stage set to operate at a significantly high gain. 

The first transistor functions as a pre-amplifier 

Magnet motor free energy generator

The Magnet motor (or magnet engine) free energy generator is a decent, powerfull and well-looking topology of a free energy generator. It works on a principle of the powerfull neodymium permanent magnets. When the magnetic force reachs the necessary level to overcome the friction, the motor RPM ramps up and reachs the equilibrum value. In the ordinary motor, the magnetic field is generated by the electric coils, usually made of copper (Cu) or sometimes an aluminium (Al). Because both copper and aluminium are not superconductors (their resistance is not zero), the ordinary electric motor continuously needs the electric power to maintain the magnetic field. I repeat: The ordinary motor needs not only the initial energy, but the coutinuous supply of energy! The coils are wasting the power, turning it into a heat, because of their

Device harvests and reflects energy from ambient TV and cellular transmissions

August 14, 2013

Researchers demonstrate how one payment card can transfer funds to another card by reflecting energy from ambient RF signals acting as both power source and communication medium.

University of Washington engineers have created a new “ambient backscatter” wireless communication scheme that allows two devices to communicate with each other by reflecting ambient TV and cellular transmissions — batteries not required.

The researchers built small, battery-free devices with antennas that can detect, harness and reflect one of the ambient radio-frequency (RF) signals, which then is picked up by other similar devices.

SOLAR CELL CHARGER

Abstract
Following a research trip to Sabana Grande, Nicaragua during which we looked into a variety of different problems faced by the local population, we worked towards designing a solar-powered cell phone charger that can be built indigenously. This was found to be of primary importance because of the large number of cell phone owners in Sabana Grande with no access to grid electricity, meaning that they are forced to pay C$ 5-10 per charge for their cell phone, which adds up to a significant investment over time.
To address this concern, our team worked with a cooperative in Sabana Grande who already make and install large solar panels in the town. We designed a small charger panel and the associated circuitry to eliminate the need to cut the solar cells, getting the appropriate voltage and power output through a DC-DC step-up converter. We designed a final prototype that should be able to charge any of the commonly used local phones in 10-12 hours of direct sunlight.
