Samsung unveils secretive smartphone SCH W789

Samsung looks to have taken the humming world of personalised tech gadgetry by surprise today by officially launching the highly rumored, but quite secretive, Samsung SCH-W789 Android-based flip phone in China on Wednesday. Samsung has simply branded the phone with its model number without giving it any personality, unlike the Samsung Galaxy smartphones that received attention akin to the birth of the Catherine, Duchess of Cambridge, and husband Prince William's royal child in Britain recently.

Samsung SCH-W789 will be available for the China Telecom users for about $800.

Features wise, Samsung SCH-W789 Android flip phone comes with dual 3.3 inch HVGA touch screen displays with the resolution of 320x480 pixels. It is running Android 4.1 Jelly Bean operating system version and it is powered by a 1.2GHz Qualcomm Quad Core processor along with 1GB of RAM memory. It is a dual SIM device with CDMA + GSM support with dual-standby features. Connectivity features of the phone include Bluetooth, WiFi, Micro USB and GPS. It also boasts a relatively staid, when compared to HTC One, 5 mega pixel rear camera with LED flash.

There is no information on the internal storage of the phone at the moment but it comes with microSD card slot to expend the memory. The phone is powered by a 1500 mAh battery and it comes with pre-loaded applications like Samsung Apps and Chat On messaging.

It will be available on China Telecom for 4999 yuan (about $816). There is no word on whether the phone will be released in any other market globally but another Android flip phone that has been seen is the Samsung Galaxy Folder that might be launched globally. via Muhammad Zulqarnain Zulfi

Digital Fan Regulator Circuit Diagram

This is the project of Digital Fan Regulator Circuit diagram. The circuit presented here can be used to control the speed of fans using induction motor. The speed control is nonlinear, i.e. in steps. The current step number is displayed on a 7-segment display. Speed can be varied over a wide range because the circuit can alter the voltage applied to the fan motor from 130V to 230V RMS in a maximum of seven steps. The triac used in the final stage is fired at different angles to get different voltage outputs by applying short-dura-tion current pulses at its gate. For this pur-pose a UJT relax-ation oscillator is used that outputs sawtooth waveform. This waveform is coupled to the gate of the triac through an optocoupler (MOC3011) that has a triac driver output stage. Pedestal voltage control is used for varying the firing angle of the triac. The power supply for the relaxation oscillator is derived from the rectified mains via 10-kilo-ohm, 10W series dropping/limit-ing...

Home automation with Telegram BOT

The project I’m going to describe today it’s a sort of proof of concept that will demonstrate the possibility to remote control sensors and actuators (for example a couple of relays) via Telegram. Telegram is an instant messaging application, similar to the famous Whatsapp. Last June, the Telegram developers announced that a new set of APIs were available to develop bots. [ ]

24 Hour Timer

Description: These two circuits are multi-range timers offering periods of up to 24 hours and beyond. Both are essentially the same. The main difference is that when the time runs out, Version 1 energizes the relay and Version 2 de-energizes it. The first uses less power while the timer is running; and the second uses less power after the timer stops. Pick the one that best suits your application. Notes: The Cmos 4060 is a 14 bit binary counter with a built in oscillator. The oscillator consists of the two inverters connected to Pins 9, 10 & 11; and its frequency is set by R3, R4 & C3.The green Led flashes while the oscillator is running: and the IC counts the number of oscillations. Although it's a 14 bit counter, not all of the bits are accessible. Those that can be reached are shown on the drawing. By adjusting the frequency of the oscillator you can set the length of time it takes for any given output to go high. This output then switches the transistor; which in turn o...
