SanDisk's 128GB SD card

It's flash card season at CES (especially given the shutterbug boost by the conjoined Photo Marketing Association show), and SanDisk has a contribution with high-capacity mid-range SDXC cards.

The two SanDisk Extreme models, 64GB and 128GB, can transfer data at 45MBps. That's less than half the speed of the company's top-end Extreme Pro line of SD cards at 95MBps, but it should be good enough for many photographers and videographers.
The high capacity comes with a price premium--prices for the cards are $200 and $400--but could be useful for those shooting lots of video or traveling away from a computer. And if you're shooting raw photos--my camera's weigh in at 30MB apiece, typically--this card will hold more than 4,000 still images.
The cards are available now, SanDisk said (flying in the face of the CES vaporware trend).
The cards, with the UHS-I interface, are up to the chore of capturing 3D video in high-definition 1080p video, Sandisk said.
Also at CES, SanDisk rival Lexar announced faster but more expensive UHS-I cards, including a 64 gb
model that reaches 90MB/sec and a 128GB model that reaches 60MB/sec.
And on a more ethereal plane, Sony announced the first examples of a new flash card format called XQD. It offered 16GB and 32GB models of the cards, which so far work only in Nikon's new flagship D4 SLR.
The CompactFlash Association developed the new format as a sequel to CF. XQD offers faster data transfer speeds--125MBps in Sony's case--with faster speeds to come.

Build a Low Noise And Drift Composite Amp Circuit Diagram

How to Build a Low Noise And Drift Composite Amp Circuit Diagram. This circuit offers the best of both worlds. It can be combined with a low input offset voltage and drift without degrading the overall system`s dynamic performance. 
 Low Noise And Drift Composite Amp Circuit Diagram

Compared to a standalone FET input operational amplifier, the composite amplifier circuit exhibits a 20-fold improvement in voltage offset and drift. In this circuit arrangement, A1 is a highspeed FET input op amp with a closed-loop gain of 100 (the source impedance was arbitrarily chosen to be 100 kfl). A2 is a Super Beta bipolar input op amp. It has good dc characteristics, biFET-level input bias current, and low noise. A2 monitors the voltage at the input of A1 and injects current to Al`s null pins. This forces A1 to have the input properties of a bipolar amplifier while maintaining its bandwidth and low-input-bias-current noise.

High Power Output Amplifier TDA7294

The famous SGS-THOMSON ST Microelectronics has introduced a Hi-Fi DMOS high-power amplifier circuit TDA7294, its sound great taste bile, which due to its internal circuit from input to output are field-effect devices, rounded sound Mild, delicate Rounuan.  However, with its assembly amplifier, only TDA7294 single-output power is only 70 W, BTL access law is 100 W from top to bottom, do not feel that power cushion. The author several tests, used to promote TDA7294-level, direct-drive one to four pairs of high-power transistor parallel, the output of strong currents, the power output of 400 W (mono), and the circuit is simple and no need to debug that can reliably work Basically, the IC has maintained a sound and performance.  Ruzuo The figure below shows, R6 for the feedback resistor, the author of the value in debugging 22 k Ω more appropriate, R6 also decided this circuit gain, the gain value will increase.  Quiescent current depends on the power of R7, R8, when its value…

Full Power Mobile Phone Jammer Circuit Diagram

Full Power Mobile Phone Jammer Circuit Diagram.To day if we are talking about expert Cell phone Jammers we are conversing about this schematic underneath. First off all you should be very very cautious how to use this apparatus. Its completely illegal and so the reason. I post this Circuit is only for educational and testing causes. This type of apparatus is being utilised by security for VIPS, particularly at their limousines to avoid blasting device initiating while the vehicle passes from the goal cell phone-bomb. Off course there are those who use it to make a antic or to make the persons crazy in the rectangle block you are. 
The power of the jammer is currently sufficient to do your thing, but certainly you can place a 30W linear power amp at the RF output and impede a much wider locality. So, Be pleasant individual with that and recall that there are people who may need desperately to obtain or make a call and one of them could be you! And if you can't oppose of functioning …
