Octave:3> File Operations

  • April 19, 2020
Part 10 of 11 in the series GNU Octave

Generally Matlab/Octave scripts work on processing section of data which are generated from some kind of experiment or other events e.g. image processing. It is not possible for a user to enter value of each pixel manually in a processing algorithm. It is needed to read the image file directly and import data into variable in workspace.


DIY two-channel 120W DC power supply

  • March 28, 2020
Part 1 of 1 in the series DIY Electronics

DC power is the basic need for any electronics project to start. Though batteries are good for small projects and also recommended due to the stable supply of current. But with increased power demand for more sophisticated projects batteries don’t seem a very good option to work with. A good bench supply or power adapter is handy and can be easily procured, but there is no match for custom-tailored design, specifically suited for the need. This is the story of a DIY two-channel 120W twelve volts fixed DC power supply.


GNU Octave – Scientific Programming Language

  • October 8, 2019
Part 1 of 11 in the series GNU Octave

GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab.


Strategy for component placement

Part 4 of 10 in the series PCB Design

The best PCB layout starts on the foundation of component placement. It is wise to not rush the process. Every extra iteration should add up niche a feature or remove a short-coming. Picking up a small detail and reducing the effort of routing by this creative process is the most challenging phase in PCB design life-cycle. But it’s totally worth it.


Selecting a PCB stack-up for EMC compliance

  • May 1, 2019
Part 3 of 10 in the series PCB Design

Good PCB stack-up is very effective in reducing differential and common mode emission from the board. Choosing a PCB stack-up in the design process is analogs to the foundation for a house. Hence selecting it carefully can save a lot of costs afterward occurring towards mitigation of EMI/EMC issue.


15 PCB Layout guidelines to achieve EMC requirements

  • April 20, 2019
Part 6 of 10 in the series PCB Design

The PCB layout doesn’t have a fixed set of rules, hence every designer generally employ a set of guidelines while using their engineering judgement. These Guidelines set out best practice to reduce the cost of boards and to minimize the risk of errors arising during manufacture.


4 steps to review the PCB layout

  • April 10, 2019
Part 7 of 10 in the series PCB Design

While some portions of the circuit performance are dictated by the schematic and BOM, the PCB layout finally decide the fate of design. During layout, we often need to use engineering judgment on the trade-off between the size, cost, testability, and manufacturability of the board.


Board bring up: Giving life to the design

  • April 9, 2019
Part 10 of 10 in the series PCB Design

Board bring – up is a planned process whereby an electronics system, including assembly, hardware, firmware, and software elements, is successively tested, validated, and iteratively debugged in order to attain manufacturing readiness


100 Point checklist for schematic design

  • April 6, 2019
Part 2 of 10 in the series PCB Design

We have categorized the checklist in multiple sections for a systematic checking. There are many details that go into making a successful first – run design, and this checklist helps prevent bugs from marrying a healthy design otherwise.


Avalanche Diode

Part 2 of 2 in the series Diode

Avalanche diode is a subcategory of diode designed to work in reverse bias and go through avalanche breakdown process at a certain voltage. With avalanche in control let’s make the electron drive safer through semiconductor Valley even in turbulent potential conditions.


Introduction to diode

  • February 13, 2018
Part 1 of 2 in the series Diode

The diode is one of the basic non-linear circuit components which conducts the current in only one direction. In operation, it is analogous to a mechanical check valve that allows the flow of fluid in one direction and blocks the flow in another direction. Similarly, diode also allows the flow of electron in only one direction, known as the forward direction. This unidirectional behavior is also known as rectification and is used to convert alternate current(AC) to direct current(DC). It would not be wrong to call this basic element as the flag bearer of the electronic edge.
