Unless your home is very new, you will lose some heat through draughts around doors and windows, gaps around the floor, or through the chimney. Professional draught-proofing of windows, doors and blocking cracks in floors and skirting boards can cost around £225, but can save around £45 (£55 in NI) a year on energy bills. DIY draught… Continue reading Draught-proof windows and doors

Switch off standby
You can save around £55 (£45 in NI) a year just by remembering to turn your appliances off standby mode. Almost all electrical appliances can be turned off at the plug without upsetting their programming. You may want to think about getting a standby saver or smart plug which allows you to turn all your appliances off… Continue reading Switch off standby
Binary to Decimal and Decimal to Binary Conversion
The number system that we are mostly familiar with is a decimal number system. The decimal number system has a base of ten which implies that there are ten numbers by the help of which we can represent any number of the decimal family. The numbers are from 0 to 9. Representation is such as… Continue reading Binary to Decimal and Decimal to Binary Conversion
Binary Number System
What is the Binary Number System? In digital electronics Binary numbers are the most important tool for giving digital inputs. Now before understanding binary number system, we have to understand decimal number system, which we use in our daily life. The number system first introduced in human history for counting purpose. Different numbers for counting… Continue reading Binary Number System
Binary to Octal and Octal Binary Conversion
We know that binary and octal are two different kinds of number systems whose bases are 2 and 8 respectively, i.e. they use 2 and 8 digits respectively to represent their numbers and these numbers are 0, 1 (for binary) and 0, 1, 2, 3, 4, 5, 6, 7 (for octal). Now we can transform… Continue reading Binary to Octal and Octal Binary Conversion
Octal Number System
In early days octal number system was mostly used in minicomputers. The word “OCT” means eight. The octal number system says that it is a number system of base 8 which means that we require 8 different symbols in order to represent any number in octal system. The symbols are 0, 1, 2, 3, 4,… Continue reading Octal Number System
Digital Electronics: Basics and Definition
What is Digital Electronics? We know there are two types of signals, one is analog or continuous signal and the second one is Digital or discrete signal. So the science or field of research in the area of engineering is termed as Analog and Digital Electronics respectively. Now coming to the area of Digital Electronics,… Continue reading Digital Electronics: Basics and Definition
Arduino vs Raspberry Pi
What is an Arduino? Arduino is an open-source hardware development board. It has a programmable circuit board and a software (IDE- Integrated Development Environment) that runs on Mac, Windows, and Linux. Arduino was developed at the Ivrea Interaction Design Institute by Massimo Benzi in Italy. It was developed for fast prototyping, and aimed at people… Continue reading Arduino vs Raspberry Pi
Thyristor Protection
Protection of a device is an important aspect for its reliable and efficient operation. Silicon Controlled Rectifier (SCR) are a very delicate semiconductor device. So we have to use it in its specified ratings to get desired output. SCR may face different types of threats during its operation due to over voltages, over currents etc.… Continue reading Thyristor Protection
Rating of SCR or Thyristor
Thyristor ratings or SCR (Silicon Controlled Rectifier) ratings are very much required for operating it in a safe zone. The reliable operation can be done when a thyristor does not violate its voltage and current rating during working period. A thyristor, or SCR may have several ratings, such as voltage, current, power,,, turn on time,… Continue reading Rating of SCR or Thyristor
