In this part of our practical electronics tutorial we will learn about diodes. Like resistors and capacitors they are also very common. They are simple component with two terminals. But unlike resistors they are polarized. That means two of its lead are not equivalent and cannot be swapped. Before moving any forward let us see how they look. Fig. Few Common Diodes Read more about diodes
Capacitors are two terminal electronic component used to store energy in form of electrostatic field. They are one of the most commonly used components. Among the many uses, some are :- Providing a bypass path for noise Smoothing voltage of power supply Blocking DC current (allowing only AC current to flow) Read more about capacitors.
Recently I got the opportunity to work with an evaluation kit from element14. They bring development and evaluation kit for latest microcontroller, sensor and other electronic solutions introduced by several top notch companies. And user like me get the chance to get introduced with latest in technologies. And what is real worth telling is that these kits are really low cost ! For example Freescale recently introduced several MEMs sensors to measure parameters such as Altitude. Atmospheric pressure. Magnetic field (to find orientation, like a compass) Accelerometers. All these are recently launched and thus were ultra modern with very small size and consumed minimal amount power. The xtrinsic sensor board from free scale has all these sensors on one small PCB. Fig. xtrinsic sensor board Xtrinsic MPL3115A2 Pressure Sensor – For sensing atmospheric pressure and altitude data. Altitude data can me measured with an accuracy of 30cm. Output can be selected in meters or Pascal. It is available in a small 3 x 5 x 1.1 mm LGA package. Interface is standard digital I2C, thus can be used with any type of microcontrollers. You can download the datasheet of the MPL3115 from the link. More information about MPL3115. MMA8491, 3-Axis Digital Accelerometer – Tilt and acceleration sensor. Digital interface (I2C). Range of measurement 8g. Output data 14bits. Sensitivity of 1mg. […]
As the journey enters its 16th year, Techniche – the annual techno-management festival of IIT Guwahati is set to write new chapters as they introduce the Model United Nations Conference as one of the highlights of the fest organized in collaboration with UN Information Centre for India and Bhutan. The MUN Conference is a perfect imbiber of all that Techniche seeks to achieve – to ideate innovation, nurture leadership and kindle global insight and aims at promoting the MUN culture in North-East India. Model UN conferences are a simulation of UN conferences and committees. Students take on the roles of diplomats from different countries, representing their nation in discussions and debate on a particular agenda topic in the conference. These agendas reflect issues taken up by the UN for discussion. Delegates must research their allotted countries in great detail, understanding their own foreign policy and thus the considerations and compulsions that determine state behaviour on the international stage. They must also research their committee agenda, fully exploring the intricacies of the issue at hand, including the background, history, its treatment in the UN system, resolutions passed on it, major countries involved, causes, consequences, past action and more. Finally, delegates must research and propose innovative and feasible solutions to the problem, within the framework of the organ or agency they are […]
Resistors are one of the most basic electronic component. They opposes(or resists) the flow of electric current through them, that is why they are named resistors. This article introduce you to resistors describing how they look, how to measure their value, how to solder them and how to identify them in a schematic. Read more about resistors.
Over the years I have seen people just open up the mouth without thinking. This is more common in the young age group like those of students. Often this also miss leads others. Recently we posted and ad on Facebook for our low cost development board which was priced at Rs. 299. Some guy without thinking a minute, compared it with a even lower cost product from some other vendor. What my point is that those two products are NOT similar ! Their are HUGE differences ! So I thought I should make out those differences stand out. Power Supply Our Board Probots’ Board Has built in 12V to 5V regulator circuit built using 7805 IC. No regulator. Advantage You can power up the board using an adapter of any voltage output between 9v to 18v Using higher voltage adapter has the advantage that power from it can be used to driver higher voltage devices like relays or motors. You can power up using a 5v adapter only! If you need 12v supply to power relays or motors you need a separate adapter or battery. Power Switch Our Board Probots’ Board Has an on/off switch No on/off switch Advantage Easy power control. Frustration on long run. Prototyping Area Our Board Probots’ Board Has large prototyping area […]
We wish all our friends a very happy Bengali New Year !

Hi All, I was adding support for some chips with big flash memory (like ATmega2560 etc.) in my Programmer Software eXtreme Burner – AVR. But right now I do not have any ready setup with ATmega2560 so I ask anyone of you who have got a ATmega2560 (or ATmega128) setup to please carry out a simple test. Just download the eXtreme Burner AVR 1.3 Beta. And try to flash the following hex files. Test Hex File for ATmega128 and ATmega2560. And update me the details via a comment on this page. Serial Interface. Now your USBasp can double as a USB to serial converter at NO extra cost! We now have a basic serial terminal integrated in the eXtreme Burner AVR ! The terminal can be launched from the Tool Menu. But you need a modified USBasp Firmware to use the terminal. It is available from here. USBasp Firmware with UART Support. eXtreme Burner AVR v1.3 Beta !
One of the most common place where small MCUs are used is to drive big seven segment displays in public area. For example the bank token number, flight or train schedule, train coach number, production volume (in factories), current forex(in banks) or gold rates etc. Since these are public display they should be big (and bright) enough to be seen from a distance of few meters. And due to their bigger size(and high brightness) they require 12V supply for each segments. Current requirement is also high. All these call for a sophisticated circuit, since these type of circuit is very common we have developed a compact board with integrated high voltage driver circuit coupled with an AVR 8 bit CPU. High Voltage Seven Segment Display Driver Board Further information, datasheet and user manual will be available as soon as the product is offered for sale. More Images
