10 Amp 13.8 Volt Power Supply Circuits Diagram I actually activated this and advisedly destroyed several 2N3055’s by shorting the emitters to ground. In all cases the transistors opened up and no beneficiary to emitter abbreviate occurred in any transistor. In any event, the alternative ambit in Figure 2 will accord you that added accord of apperception back a actual big-ticket radio is acclimated with the ability supply. The ambit in Figure 2 senses back the voltage exceeds 15 volts and causes the zener diode to conduct. Back the zener diode conducts, the aboideau of the SCR is angry on and causes the SCR to abbreviate which assault the 15 amp agglutinate and shuts off the achievement voltage. A 2N6399 (Tech America) was acclimated for the SCR in the ancestor but any acceptable SCR can be used. While over voltage aegis is a acceptable idea, it should not be advised a acting for ample calefaction sinks. I alone feel the best aegis from over voltage is the use of ample calefaction sink...

This circuit use TA7222AP to amplifiers audio signal .The price only $0.99 and can provide 5.8 watt with Muting Control.Power supply can use for 8-12Vdc it is a good idea to use for car audio power amp , coin-op machine game, security system etc. Fig 1.

Nokia has started rolling out its Windows Phone 8 'Amber' update for its Lumia smartphone lineup, which brings with it a number of major software improvements. Nokia's Amber update builds on Microsoft's most recent Windows Phone 8 update and sees the Finnish firm further outdoing HTC and Samsung with unique Windows Phone features. The most notable new aspect is Amber's added camera features. The update adds Nokia's Pro camera app that debuts on the Lumia 1020 to some of its older phones, including the Lumia 920 and Lumia 925. Nokia's Smart Camera app is also made available to more devices, as the Amber update sees the app arriving in the Windows Store. Detailing the Smart Camera app on its blog, Nokia said, "The app brings a slew of different options – use Best Shot to find the sharpest image from a series of ten; combine several shots of people in movement into one with Action Shot; heighten the appearance of speed by blurring the background with Motio...
