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: Output...

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 possible. ...

Antennas are much shorter than quarter wavelength impedance obtained is very small and highly dependent on the frequency. It was a difficult game impedances over a decade of frequency coverage. Instead, the phase of the input source-follower FET Q1. A high impedance input successfully bridges Antenna characteristics at any frequency. 1/4 wavelength Active Antenna Circuit Diagram   transistor Q2 is used as a follower, to provide a high impedance load for Q1, but more importantly that it makes to drive low-impedance amplifier coupled to commonly Q3, which each receive a voltage amplifier. Q3 Q4 turns transistor output impedance is relatively low in impedance, which is enough to drive 50 Three dimensional receiver, Antenna input impedance.

  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...

  Whereas it's traveled 11.6 billion miles to interstellar space, Voyager 1's software isn't as high-tech as you may believe. In detail, it has less than 40 KB of recollection. To put that in viewpoint, your 16 GB iPhone 5 has about 240,000 times the recollection of a Voyager spacecraft. NASA developed Voyager in the 1970s in a pre-computer era when scientists had to rely solely on pencil, paper, chalkboards and their own mathematical abilities. While that appears unimaginable in a time when we contain decades' worth of computational power in our pouches, Voyager 1 is one of NASA's most thriving missions, and project researcher Edward Stone states he wouldn't have changed a thing. "It's astonishing it's continued as long as it has," pebble notifies Mashable. "I don't know how we could have done things much better than they were finished. I mean things do wear out, and we've had to swap to some of our backup schemes, but luckily we ...

Does the world really need yet another digital camera? The correct answer would be an unequivocal and resounding, “Yes!”. Well, you know that the camera industry is going to continue moving forward with ever higher resolution, not to mention advancements in video recording technology, but how about the operating system of the camera? That has more often than not been overlooked, so Samsung might be on to something here with their maiden attempt at an Android-powered camera, the Samsung Galaxy Camera. Yes sir, we are referring to the mobile operating system from Google that sees actions on smartphones and tablets, now making its way to a camera. How does it fare? Hit the extended post to know more. The Samsung Galaxy Camera can be said to be a smartphone sans the “phone” bit. After all, it will come with the most recent Android 4.1 Jelly Bean operating system, not to mention carry a slew of connectivity options that would even turn some smartphones green with envy – such as 3G, 4G and W...
