This battery charger is for 12V Seales Lead Acid (SLA) battery. It is actually a half-wave rectifier. It only charges the battery on every half cycle. The plug pack doesn’t like this as it leaves residual flux in the core of the transformer and causes it to overheat. There are a number of points we [...]

Bluetooth is a short – range wireless technology that enables Connectionless communication between devices . Bluetooth Technology redefines the very way we experience Connectivity . The connectivity between the bluetooth – enabled a device is based on device authentication . The connectivity Does not take into account the authentication of the user . The lack [...]

All fuse and lock bits are programmable. This programmer has intelligent onboard firmware and connects to the serial port. It can be used with [...]
Stepper motors come in two varieties: permanent magnet and variable reluctance. (The reader may be familiar with hybrid motors, which are indistinguishable from permanent magnet motors from the controller’s point of view.) Permanent magnet motors usually have two independent windings, with or without center taps. Center-tapped windings are used in uni polar permanent magnet motors. [...]
Circuit Description There are many instances where a simple and reliable power amplifier is needed – rear and centre channel speakers for surround-sound, beefing up the PC speakers, low powered tweeter amplifier, etc. For those who want to build their own ‘Gainclone’ amplifier, this will certainly do the job This project (unlike most of the [...]
