Making Li-ion batteries safer: Cell balancing as an important design feature

Making Li-ion batteries safer: Cell balancing as an important design featureThe energy density of Lithium-ion (Li-ion) batteries is two to ten times more than other battery technologies. But, Lithium-ion uses a flammable substance as an electrolyte. If overcharged or overheated, Li-ion cells are a fire risk. 

Cell balancing equalizes the voltages and state-of-charge (SOC) among the cells, when they are at full charge. Balancing can be either voltage-based or SOC-based. It’s a non-trivial task that – ideally — aims both to increase the life of a battery pack and to enhance battery safety.

Virtual Retinal Display

A machine consists of many sub systems working together to perform a certain task. The information from the electronic devices are retrieved from the machine sub systems as binary code. All this information is presented in a user readable formatthrough a display device. The display technology has seen a rapid growth in the past few decades from the old CRT (Cathode Ray Tube) displays to the presently in demand LCD (Liquid Crystal Display) and LED (Light Emitting Diode) displays. The LCDs and LEDs consists of two dimensional arrays of individual display units (pixels) whose number to size of display determines the clarity of the display (resolution).

Epson to Release new T Series Robots to expand its SCARA LineupEpson Corporation, a global technology leader, has announced to expand the lineup of industrial SCARA (Selective Compliance Assembly Robot Arm) robots by adding a new T series of robots. The first model in the series to be released is T3, which will be made available in limited markets in late March followed by its rollout in other regions. 
 
The T3 model has been designed primarily for simple material handling applications like test machine loading/unloading. It would offer the companies and opportunity to employ robots for non-creative and repetitive work which has been usually performed by operators like transporting components.

B&K Precision Introduces two new Models to Expand its Bench LCR Meter Family

B&K Precision, a leading designer, and manufacturer of test & measurement solutions, has expanded its bench LCR Meter family by adding two new models. The newly added 894 and 895 models extend the family’s test frequencies up to 1MHz, offering test frequencies from 20 Hz to 500 kHz, and 20 Hz to 1 MHz, respectively. Besides, these are capable of measuring inductance, capacitance, and resistance with 0.05% basic impedance accuracy. 

Digital Dice - Displaying Custom Characters on 16X2 LCD

Pawan Kumar

In this project, a digital dice will be designed. The objective of this project is to teach that how custom characters can be displayed on an LCD. In Arduino projects using 16X2 LCD for display, the characters can be directly printed on one of the two rows using print() function of the LCD library of Arduino.

However, sometimes displaying custom characters on the LCD is the demand of the project. The same feature has been illustrated in this project by designing a digital dice. A digital dice is digital version of the regular dice. Any dice has six faces on which numbers from 1 to 6 are printed. On throwing a dice, one of the face and so one of the numbers between 0 and 7 appears on the upright face. It can be any random number between 0 and 7.

+/-5V supply from 9V Battery

Op-Amps require dual polarity supply for their proper operation. When working with battery supply, it is difficult to get dual power supply from battery supply as it requires more steps and components. So, presented here a simple circuit that provides +/- 5V from few components.

It is built around monolithic CMOS voltage converter IC ICL7660A (U2) and linear voltage regulator IC LM7805 (U1). ICL7660A is configured as voltage inverter to convert the positive 5V supply to negative 5V supply. The linear voltage regulator converts the 9V battery input into regulated 5V. The regulated 5V output from IC 7805 is given to pin 8 of IC U2.

Arduino library for DC motor control - Circuit diagramHere I present Arduino library to control DC motor. The library is having so many facilities and flexibilities that it can control any DC motor in required manner. The library is designed as per the industrial motion control requirements. The library is having 16 different functionalities such that it can control the motor in most versatile manner. Here is the list of facilities in library.

Here is the list of facilities in library: It controls direction of rotation of motor, it controls speed of motor from 0-100%, it can provide soft start to motor in specified time – means motor speed will increase from 0% to desire level in specified time, it can provide smooth stop to motor in specified time - means motor speed will decrease from current speed to 0% in specified time, it can apply jog control to motor in either direction – means motor will jerk in specified direction, and it can apply DC BREAK  (means immediate or emergency STOP) to motorHere is the list of facilities in library.

Arduino based Logo Version 1.3 Flame Detector module

One of the Henry’s Bench tutorial has tried to explain the characteristics of the Logo Version 1.3 Flame Detector module. It represents all those similar devices which are specially designed to interface with microcontrollers. The device also consists of op-amp circuitry, an IR detector, an LED indicator, and sensitivity adjustment.

The most important portion is the IR detector, which is sensitive to light wavelengths and hence typical of flames. It means that when a flame is presented, the red LED of the module is turned on and its output low is accordingly set.
