This is a Simple 1.5V Battery to 5V Voltage Converter Circuit Diagram. Stable and secure 5V DC (at 200mA max) from an ordinary 1.5V AA sized cell. At the heart of this circuit is IC1 MAX756 from Maxim, which is a CMOS step-up DC-DC switching regulator for small, low input voltage or battery-powered systems.   Simple 1.5V Battery to 5V Voltage Converter Circuit Diagram MAX756 accepts a positive input voltage down to 0.7V and converts it to a higher pin selectable output voltage of 5V (or 3.3V). Typical full-load efficiency for the this IC is greater than 87%. Max756 combine a switch-mode regulator with an N-channel MOSFET, precision voltage reference, and power-fail detector in a single monolithic device. The MOSFET is a “sense-FET” type for best efficiency, and has a very low gate threshold voltage to ensure start-up under low-battery voltage conditions (1.1V typ). The circuit can be easily wired on a very small rectangular common PCB.All connections should be kept as short as poss...

Here is very Simple build power supply Electronic Circuit Project of   15-V 1-A Regulated Power Supply circuit.   The supply receives - 20 V from the rectifier/filter which is fed to the collector of the Darlington pnp pass transistor, a TIP105. The base drive to the TIP105 is supplied through resistor R5. The base of the TIP105 is driven from Vz terminal at pin 9, which is the anode of a 6.2-V zener diode that connects to the emitter of the uA723 output control transistor. 15-V 1-A Regulated Power Supply Circuit Diagram: The method of providing the positive feedback required for foldback action is shown. This technique introduces positive feedback by increased current flow through resistors R1 and R2 under short-circuit conditions. This forward biases the base-emitter junction of the 2N2907 sensing transistor, which reduces base drive to the TIP105. 

The circuit 1Watt LED for AC LED uses a 1 Watt Luxeon LED white, its voltage is 3.6 volts and consumes 350 mA at maximum. It is important to note that this circuit can generate a lethal shock if handled carelessly. Most of the points are on the network, so that care should be taken when handling. 1 Watt LED em AC Circuit Diagram

Except for use as a normal Battery Charger , this circuit is perfect to 'constant-charge' a 12-Volt Lead-Acid Battery , like the one in your flight box, and keep it in optimum charged condition. This circuit is not recommended for GEL-TYPE batteries since it draws to much current. The above circuit is a precision voltage source, and contains a temperature sensor with a negative temperature coλficient. Meaning, whenever the surrounding or battery temperature increases the voltage will automatically decrease. Temperature coλficient for this circuit is -8mV per °Celcius. A normal transistor (Q1) is used as a temperature sensor. This Battery Charger is centered around the LM350 integrated, 3-amp, adjustable stabilizer IC. Output voltage can be adjusted with P1 between 13.5 and 14.5 volt. T2 was added to prevent battery discharge via R1 if no power present. P1 can adjust the output voltage between 13.5 and 14.5 volts. R4's value can be adjusted to accommodate a bit larger or s...

Power supply circuit to generate output below were variations between 1.3V DC to 12.2V DC with 1A current. In addition, the power supply circuit is also equipped with over-current protection or shield against belebih flow. Power supply circuit is very simple, but the quality is quite good, made her basiskan regulator IC LM723 is a pretty legendary. Description : R2 to set the output voltage. The maximum current is determined by R3, over-current protection circuit inside the LM723 to detect the voltage on R3, if it reaches 0.65 V, the voltage output will be off her. So the current through R3 can not exceed 0.65 / R3 although output short-circuit in his. C3 and C4 are ceramic capacitors, as much as possible directly soldered to the PCB, this is because the LM723 is prone to oscillation that is not cool. LM723 works with 9.5V input voltage to 40 V DC and the LM723 can generate its own current of 150mA when the output voltage is not more than 6-7V under input voltage. Specifications : Ou...

  Android 4.4.1 landing soon and fixes Nexus 5 camera . The Nexus 5 from Google is quite an awesome device, however its camera isn’t the greatest. Even though the Nexus 5 ′s camera features a optical image stabilization, taking shots from it are painfully slow and generally out-of-focus. Google is aware of this and as per The Verge, a new update scheduled to be released in the next few days fixes a lot of issues with the Nexus 5 camera. They’ve managed to get a hands-on experience with Android 4.4.1 and here is what they have to say: Speed is a theme for the update, and the Nexus 5 ′s camera really does feel faster across the board. The app launches a full second quicker than it did before the update, meaning you’ll miss many fewer shots than before. There’s also a new progress indicator in HDR+ mode, which makes the process, longer by necessity, feel a lot more straightforward. It’s the first of what Burke says will be a series of interface changes, as Google tries to make Andro...
