Battery Charger Using Power from Grid

A PIC16F676 microcontroller is being used in this project to control a solid stat relay and to monitor the battery voltage in order to become useful in alternative energy applications by making a battery charger.

Creating Prank Device Using the Haunted USB Cable

The purpose of developing the haunted USB cable is to send random keystrokes from time to time to a user while implementing a keyboard and driving the user mad.

Battery Discharger with Precision

The project uses a cheap and reliable discharger circuit with an easy visual indication of the battery’s state as it creates a precision battery discharger for 8.4V 7-cell NiCad or NiMH batteries.

LiPo Monitor System Known as Simple-Volt

The project is built around a PIC microcontroller in order to build the Simple-Volt which is a tiny, lightweight R/C battery voltage monitor/alarm system.

Building A Universal Solar Powered Charger

With minimal electronic knowledge and even cheaper cost, the project aims to create a universal solar power charger with the option of changing the panel whenever desired.

Smart & Fast Battery Charger for NiCd/NiMH

The project utilizes MAX712/MAX713 fast charge controllers in order to build a smart & fast NiCd/NiMH battery charger.
