All you want to know about Electric Vehicle Batteries The speed, mileage, torque and all such vital parameters of an electric car solely depends on the specification of the motor and the battery pack used in the car. While using a powerful motor is no big deal, the problem lies with designing a Battery Pack that could source enough current for the motor for long time without degrading its lifespan. To cope up with the voltage… |

An Engineer's Introduction to Electric Vehicles (EVs) According to a forecast by International Energy Agency, the use of Electric Vehicles will grow from 3 million to 125 million by the year 2030. That is almost 41 times of what it is today, with the increasing demand of fossil fuel and problems with pollution it seems most likely to happen. Owing to that, all major IC Engine Car manufacturers like Ford and GM are slowly… |

DIY Self Balancing Robot using Arduino After being inspired by RYNO motors and other self-balancing scooters from Segway, I always wanted to build something of my own Arduino Segway Robot. Thinking for a while, I decided to build a Self Balancing Robot using Arduino. This way I would be able to grasp the underlying concept behind all these scooters and also learn how the PID algorithm works. … |

Smart Blind Stick using Arduino Ever heard of Hugh Herr? He is a famous American rock climber who has shattered the limitations of his disabilities; he is a strong believer that technology could help disabled persons to live a normal life. In one of his TED talks, Herr said, “Humans are not disabled. A person can never be broken. Our built environment, our technologies are broken and disabled. We the… |

Float Charger Circuit for 12v SLA Battery A float charger, also called as maintenance charger or smart charger, is used to charge a lead acid battery to top-up the self-discharge capacity. Self-discharge happens in a battery if not in usage for long time i.e., the terminal voltage begins to decrease. If this float charger is connected to the battery the self-discharged capacity can be topped up which is to full… |

DIY Speedometer using Arduino and Processing Android App In this project we make a Cool Speedometer for bikes or any automotives by using Arduino which broadcast the speed using Bluetooth to an Android application that we created using Processing. The complete project is powered by an 18650 Lithium cell and hence highly portable along with your vehicle. To spice it up a bit more I have added the option of… |

Raspberry Pi Emergency Light with Darkness and AC Power Line Off Detector In this session we are going to make a 9WATT Emergency Lamp using Raspberry Pi and Python. This lamp will automatically detect the darkness and absence of AC power supply, and light up when there is power failure and proper light is not there. Although there are various emergency lamps available but they are purely dedicated to serve single purpose… |
