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...

Measure AC mains voltage without using a multimeter. All you need to do is to slightly modify the light dimmer fitted at the base of a table lamp for use as a voltmeter . When the dimmer is turned anticlockwise to a point where the filament glow is just visible, that point can be used as the reference point for measuring the voltage. Light dimmer Circuit Diagram First, remove the old knob and fix a circular white paper around the shaft. Now put back a skirted knob with a cursor as close to the paper as possible and mark two extremities of the pot on the paper as CW and ACW (see Fig. 2). AC volts scale marking Switch on the lamp via a variac and feed 50 volts. Rotate the potmeter knob anticlockwise until the filament glow is just visible and mark that point against the cursor as 50V. Keep on increasing the voltage to 100, 150, 180, 200 and 220 using the variac and calibrating the scale for all the voltages. Now a voltage scale is created. The only snag is that the voltage is increasing ...
