Samsung has introduced a 128 GB flash memory

Samsung has introduced a 128-GB flash memory eMMC 5.0 Smartphone mass segment. Samsung has introduced high-performance drives for smartphones based on a three-bit memory NAND eMMC 5.0. The capacity is 128 gigabytes of new products. These drives planned to equip smartphones and tablets mass segment. Flagship smartphone is already equipped with a 128-gigabyte drives UFS 2.0 or eMMC 5.1. Together with the new development to get such a capacious drive will and mid-priced device. The drive shows the data rate mode, sequential reads of 260 MB / s, which coincides with the index of memory-class MLC NAND eMMC 5.1. The speed of random read and write IOPS is 6000 IOPS and 5000 respectively, which is much superior to the present distribution of the memory card. This means that the new device is perfectly cope with multitasking and processing of high-resolution video. The new Samsung device has allowed the company to strengthen its own position in the market 3-bit NAND-memory, offering not only so...

Flash Lights with HT2014L

Flash Lights with HT2014L This scheme is almost the same with a flash light with LM3909. In this scheme only requires IC HT2014L as a leader, and a resistor and LED. For voltage here need ration power around 4.5 V. You can apply this series to a wider scale in comparing the use IC LM3909. For the scheme are below:

Slave Flash for Underwater Camera

The flash module in this circuit comes from a  Fuji disposable camera. The author’s design  is based on various ideas on this subject that  can be found on the Web. The guide number  [1] of the flash is approximately 14 in the air  and close to 6 underwater. The flash intensity  is not adjustable. This flash unit is primarily intended to be used  for underwater photography, which is why  the author fitted it in a  case originally used for  a Nikon Coolpix 7900.  Of course, it can also  be used for dry-land  photography. The flash  module is powered by  a 1.5-V battery, which  must supply approximately 30 to 40 mA  to charge the capacitor. The control portion is built around a  PIC12F675, which is  powered by a 3-V button cell. Its current consumption is practically negligible  just a few  milli amperes while the flash is active and only  600 nA the rest of the time, when the micro-controller is in the standby state. For this rea-son, the unit does not have an on/off button. The flash from ...
