3D Printing

    A 3d printing is a computer aided manufacturing (CAM) device that creates three dimensional objects. It starts with a virtual design of the object to be printed; the computer software can scan existing items or allow you to create a unique design. The computer then takes that model and slices it into thousands of horizontal layers. The printer reads each one of those slices and prints it out layer by layer to build a solid three dimensional object. This process is called additive manufacturing.
Many different materials can be used for 3D printing , such as ABS plastic, PLA, polyamide (nylon), glass filled polyamide, stereo lithography materials (epoxy resins), silver, titanium, steel, wax, photopolymers and polycarbonate.
Types of 3d printing
1)      Fused Deposition Modelling- It is an additive manufacturing technology commonly used for modelling, prototyping, and production applications.
2)      Stereo lithography- It is an additive manufacturing process which employs a vat of liquid ultraviolet curable photopolymer "resin" and an ultraviolet laser to build parts' layers one at a time.
3)    Selective laser sintering- It is an additive manufacturing technique that uses a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, metal (direct metal laser sintering), ceramic, or glass powders into a mass that has a desired three-dimensional shape

Automatic Irrigation system using 8051

 INTRODUCTION https://www.youtube.com/watch?v=HPO6GTjQNTs In a country like India, the agriculture plays the important role in the economy and development of the country. At the present era, the farmers have been using irrigation technique in India through the manual control in which the farmers irrigate the land at the regular intervals. This process sometimes consumes more water or sometimes the water reaches late due to which the crops get dried . There is a need in the residential/commercial irrigation industry for an irrigation controller that responds to soil moisture sensors in individual zones as a way of conserving water. An ideal controller should be "user friendly", i.e., easy to program and requiring a minimum number of keys or push-buttons to operate the controller. It should also allow irrigation to take place in zones where watering is required, while by passing zones where adequate soil moisture is indicated- To add flexibility, it should be possib

Transformer

Image
            A transformer is a magnetically coupled device in which magnetic field produced by time-varying current induction voltage in another. An electric transformer changes ac electric power at one voltage to another. The transformer two coils, these are electrically separated but linked through a common magnetic current circuit. AC current in one coil produce a flux that links with other winding and induces voltage in that. STANDARD TRANSFORMER ACCESSORIES 1)       Thermometer Pockets This pocket is provided to measure temperature of the top oil in tank with mercury in glass type thermometer. It is essential to fill the pocket with transformer oil before inserting the thermometer, to have uniform and correct reading   2)    Buchhol's Relay                                                         This relay is a gas actuated relay which is

CONDUCTORS

Conductors are materials with electrons are loosely bound to their atoms or materials that permit free motion of a large number of electrons. Atoms with only one valance electron such as copper, silver, gold are examples of good conductors. Most of the metals are good conductors Properties of electrical conductors             In equilibrium condition the conductors exhibit the following properties a)       Resistance Conductors are those substances which offer such a small resistance b)       Inductance When a conductor is used as ac supply a magnetic flux is produced, which consist of two parts. One is internal flux and other is external flux. The internal flux is very low as compare to external flux. Due to this flux linkage to the conductor itself an inductance is come into picture. This inductance results in extra voltage drop in conductors. More over this inductance is also effects to skin effect and proximity effect  c)       Electric field There is no electr
