Citing unnamed supply chain sources, as well as what we’re guessing are some better informed sorts within Samsung, the Korea Times claims that the phone will land in February at the Mobile World Congress. The handset is apparently set to hit retailers shortly after in March – just nine months after the release of its predecessor. In news that’s unlikely to surprise anyone on nodding terms with prevailing trends in smartphone upgrades, Samsung’s new kit will purportedly pack a larger five-inch OLED screen – up from the S3’s 4.8-inches - and international 4G LTE support. An unnamed deepthroat said: “Samsung wants to keep its one-year product schedule and the Galaxy S4 will be the first to match that strategy. “The S4 will see some external changes but retain its popular rectangular shape with rounded corner concept.” News of Samsung’s plans comes as it recently announced that the S3 has now sold some 20 million units, making it the company’s fastest-selling phone ever.

USB Type-C is a singular cable set out to replace a slew of other connectors by making a standard, future-proof cable. In addition to charging, the USB-C allows data transfer and video as well as connecting to Ethernet. Texas Instruments' announcement of an all-in-one USB Type-C and USB power delivery controller provides a power path that operates as a single or dual-role port which allows for many host and device power implementations. The TPS65982. The TPS65982 allows for delivery of both power and data in several alternate modes. It can be configured to support data as a downstream or upstream-facing port, or as both host and device. It also supports data rates at up to 5.4Gb/s with a standby power of 40µW - more than 50% lower than competitive offerings - to extend battery life. This is especially important in mobile devices like laptops that rely on energy maximization but demand high performance. The USB Type-C included in the new MacBook Retina. In systems requiring up ...

Compact circuit, Can be wired in parallel to existing switches This device allows one or more lamps to illuminate at sunset and turn off at dawn.Q1 and Q2 form a trigger device for the SCR, providing short pulses at 100Hz frequency. Pulse duration is set by R2 and C1.When the light hits R1, the photo resistor assumes a very low resistance value, almost shorting C1 and preventing circuit operation. When R1 is in the dark, its resistance value becomes very high thus enabling circuit operation. New Dark Activated Terrace Lamp  Circuit Diagram: Dark Activated 220 volt AC Lamp Circuit Diagram Parts: R1 = LDR R2 = 100K R3 = 200K R4 = 470R R5 = 12KR6 = 1KR7 = 470R C1 = 10nF-63V D1 = TIC106D D2 = 1N4007D3 = 1N4007D4 = 1N4007 D5 = 1N4007 Q1 = BD327 Q2 = BD337 SK1 = Female Mains Socket   Notes: R3 allows fine setting of operating threshold and R2 value can be raised to 150K maximum. Several lamps wired in parallel can be connected to the circuit, provided total power dissipation of th...

China has confirmed that the new iPhone will get the touch sensitivity display. Rumors that Apple is going to take advantage of the iPhone touch sensitivity displays Force Touch, been around for a long time. Now Asian insiders are willing to share a new piece of information: the Chinese company TPK expected by the end of this year, a significant increase in profits, which will be primarily associated with the delivery of a large number of displays Force Touch for Apple. According to sources, Apple plans to use these displays in smartphones already starting with the iPhone 6S Plus. At the moment, she applies them in hours Apple Watch, but the production of 5.5-inch displays will cost Apple 2.5 times more expensive (the price of the sensor will be $ 13-14). IPhone 6S model references in association with displays Force Touch not, so it's possible that sensitive to the levels of pressing the screen will be a distinctive feature is iPhone 6S Plus. Apple already uses Force Touch, which i...

Why you may need a zipcharge quick charger? With so many devices around these days, making sure they have enough juice to run on is essential wherever we go. The Zipcharge Quick Charger aims to help you out with that, where it comes in the form of a rechargeable power stick that takes a mere 15 minutes of charging to provide your iPod with another 20 hours of audio playback, while you get 10 more hours of talk time. Now, these are all theoretical figures, so you might want to take it with a pinch of salt. How about a 60 second charge that offers 2 hours of playback on your iPod? Charging the sleek ZipCharge for a paltry 15 minutes will store enough oomph to give your iPod an extra 20 hours of playtime or your mobile phone an additional 10 hours of talk time. If you’re in a pant-trippingly awful rush, a 60 second charge whooshes in sufficient juice to power an iPod for 2 hours, a mobile phone for 8 hours, 2 Way Radio for 1 hour 20 mins or a camera for 80 photos. So how does it work? No...

The target of this project was the design of a small portable mixer supplied by a 9V PP3 battery, keeping high quality performance. The mixer is formed assembling three main modules that can be varied in number and/or disposition to suit everyone needs. The three main modules are: Input Amplifier Module: a low noise circuit equipped with a variable voltage-gain (10 - 100) preset, primarily intended as high quality microphone input, also suitable for low-level line input. Tone Control Module: a three-band (Bass, Middle, Treble) tone control circuit providing unity-gain when its controls are set to flat frequency response. It can be inserted after one or more Input Amplifier Modules and/or after the Main Mixer Amplifiers. Main Mixer Amplifier Module: a stereo circuit incorporating two virtual-earth mixers and showing the connection of one Main Fader and one Pan-Pot. The image below shows a Block diagram of the entire mixer featuring four Input Amplifier Modules followed by four in-out...

Last week Google introduced a radical new mail app, built on top of Gmail, that promises to cut through the pain of managing your inbox. Countless apps and extensions have promised to relieve the suffering of email, and I'm always open to trying another one. I spent the past few days using Inbox as my primary email app, and here's how it works.  Inbox's approach is focused on giving you access to the most important information first, eliminating the need to dig through emails for essentials such as attachments, photos, and travel details. Its smart reading function abandons the classic chronological presentation of email in favor of grouping similar messages together and prioritizing them by importance.  The main dashboard, titled simply, "Inbox," acts as a feed of all your incoming mail, which is placed into smart categories Inbox calls "bundles." Your Inbox comes with a set of pre-categorized bundles such as travel, purchases, updates, and social media...
