Creative has added a new member to their portable Sound Blaster "E" series lineup with the E5.
This new multi-function DAC and headphone amp features a reference-grade D/A converter chip from Cirrus Logic, the CS4398, which supports up to 24-bit/192kHz PCM audio (and technically DSD 2.8MHz/5.6MHz, though this does not seem to be implemented here). In addition to the realistic analog reproduction possible from a high quality chip like the CS4398, the Sound Blaster E5 provides amplification via a Texas Instruments TI6120A2, which Creative says gives the E5 a "best-in-class 600 ohm headphone amplifier".
Another aspect of the E5 that sets it apart from the previous E1 and E3 models is the inclusion of optical digital input/output, to go along with USB and dual 3.5mm headphone jacks. The two 3.5mm jacks can simultaniously drive two pairs of headphones, and on the back of the unit there are additional 3.5mm jacks for microphone input, line input/output, and these double as optical input/output via mini TOSLINK. (This might be geared for portable use, but would serve as a fine external sound solution for desktops as well!)
The input stage of the E5 uses another Cirrus Logic chip, the CS5361, enabling high quality recording options from various sources at up to same 24-bit/192kHz. While supporting external microphones (as well as line/optical input) the E5 also has "built-in beamforming CrystalVoice microphones for audio recording and calls". And while the E5 is employing Creative's SBX sound processing chip, this DSP can be switched off with a button on the side of the device - a welcome option for serious music listening from high-resolution source material.
The Sound Blaster E5 also supports digital input from iPhone and "select" Android phones (listed compatible devices include the Samsung Galaxy S4/S5, Galaxy Note 2/3, and Nexus 5/7). For portable use the E5 has a built-in rechargeable 3200mAh lithium polymer battery, which Creative says will provide up to 8 hours of playback per charge.
The Sound Blaster E5 will be available in October for $199 at Creative's online store (and likely various other retail outlets).

A high capacity USB flash drive used to be the definition of great swag, a company could put whatever tools, media or programs on a promotional USB drive but what really counted was the size. As 128GB and larger drives started to become more common and more reasonably priced may got in the habit of dumping all their optical media to be replaced by a handful of flash drives, some bootable and some not. Take the Patriot SuperSonic Rage XT 128GB up for review at NikTech, for $80 you get 128GB of storage that can hit 200MB/s random or linear reads and is rather durable. There is nothing wrong with the drive until you realize you can pick up a 128GB Crucial MX100 and an eSATA cable for the same price or double your storage for an extra $30. Those SSDs are roughly twice as fast and every bit as rugged, so why pick up that flash drive in the first place?
"Storage capacity needs increase on a daily basis and with them so does demand and thus in the end those two result in more competition between companies and lower prices (at least most of the time). Think about it, just two years ago i was running around carrying an 16GB USB flash drive with my keychain while now i have attached a permanent 32GB one which i sometimes replace with an 128GB one if i need to carry way too much data with me."

Over at Hack a Day is a guide on how to convert your old chargers for devices you no longer use into a useful charger with a USB plug. They will need to be of the 5V variety and provide at least 500 mA in order to be useful with today's gadgets with 1A being preferable; don't go so high you are at risk of killing your device though. Apple fanatics will have to do the usual modifications to convince their iThing to accept a charge but most other devices won't care if the charger is home made or not, they just want the USB. Do try not to set yourself or any of your possessions on fire by not testing your charger thoroughly before leaving it unattended.
"If you’re like us, you probably have a box (or more) of wall warts lurking in a closet or on a shelf somewhere. Depending on how long you’ve been collecting cell phones, that box is likely overflowing with 5V chargers: all with different connectors."

Earlier today, Corsair announced the Flash Voyager GO combination micro USB (OTG spec) / USB 3.0 (standard connector) drive. Being the storage nut that I am, I got a closer look while the rest of the PCPer gang were checking out the new cases, keyboards, and power supplies. Here are some more detailed pics for your viewing pleasure:

Backwards compatibility is a big issue for PC users who do not want to have to constantly upgrade everything from connectors to add-in cards every time they do a small upgrade. That compatibility comes with a cost, many devices which should have been allowed to die long ago still live on. It is possible that one such abomination may be going away in the near future, the trapezoidal USB plug that only connects in one orientation. The USB Type-C connector will be square, similar in size to the current USB 2.0 Micro-B plug found on non-fruit based cellphones and most importantly it will not have a specific orientation required to connect. Hopefully Slashdot isn't discussing something too good to be true.
"Extreme bandwidth is nice, intelligent power management is cool... but folks should be spilling into the streets in thankful praise that the next generation miniature USB connector will fit either way. All told — just how many intricate miracle devices have been scrapped in their prime — because a tiny USB port was mangled? For millennia untold chimpanzees and people have been poking termite mounds with round sticks. I for one am glad to see round stick technology make its way into consumer electronics. Death to the trapezoid, bring back the rectangle!"

Tagged: video, usb, charger, anker
In my eternal goal to find the perfect USB charging solution for my varied use cases, I came across a 5-port unit from a company called Anker that is as close as I have found thus far. My needs are pretty concrete: lots of ports, high power to those ports and the ability to sit on a desk or table. The Anker E150 5V/5A 5-port wall charger is pretty close.
Though ideally I would like to see more than 5 ports, this capacity seems to be reasonable for most people with the standard allotment of electronics. As the name suggests, the Anker unit maxes out at 5A of output TOTAL for all 5 ports, though each port is rated at different amperage. The two ports labeled iPad will output up to 2.1A, the rest vary a bit.
Obviously the total amp output of those ports goes PAST the 5A maximum of the unit, so expect charging to slow down if you have all ports populated. I also wish that Anker would just label the outputs with their respective amperage rather than attempting to get product SEO with the current naming scheme.
Even better, the Anker E150 5V/5A 5-port wall charger can be picked up at Amazon for an impulse purchase price of $19!

The USB condom is an adapter which disables the two data ports present on your USB connector to prevent a malicious charger from installing interesting things on your smartphone, if you decide to stick it into a strange charger. Many will immediately point out that this device is much larger than a simple power adapter which makes it easier to leave behind as well as being large enough to hide nasties of its own, so you wouldn't want to borrow someones condom. If you read through the comments on Slashdot you can pick up some interesting problems that this device could cause, from devices which refuse to charge without their data connections active to devices which actively communicate the amount of power they will accept for a charge. It is unlikely your device would have an expected amperage less than the USB spec and go up in flames but it is worth knowing that the possibility exists.
"Yep, a USB condom. That term is mostly a dose of marketing brilliance, which is to say that grabs your attention while also serving as an apt description of the product. A little company called int3.cc has developed a product—a USB condom—that blocks the data pins in your USB device while leaving the power pins free. Thus, any time you need to plug a device such as a smartphones into a USB port to charge it—let's say at a public charging kiosk or a coworker's computer--you don't have to worry about compromising any data or contracting some nasty malware. It's one of those simple solutions that seems so obvious once someone came up with it."

StarTech has always had a rather large line of external USB and eSATA HDD docks, but up until now most have been limited to SATA connectivity. Now they have released a dock that's able to connect to IDE hard drives as well! It pulls off this trick by including a short IDE ribbon cable that can connect to the back of the unit (see pic below).
According to an article in New Scientist, a UK firm called Oxford Nanopore has managed to build a DNA sequencer into what looks to be an overweight USB stick. They have named the device the MinION, and it will sell for $900 later this year. It can be used to sequence DNA with as many as 10,000 base pairs in one continuous read. While it can sequence a human genome in about 6 hours, they intend the device to be used to sequence shorter genomes with tasks like identifying pathogens and screening for genetic mutations that can lead to diseases.
The company demonstrated the MinION in action recently at the Advances in Genome Biology and Technology conference where it sequenced Phi X, a virus with 5,000 genetic base pairs. A bioinformatician at Pallen Research Group stated that "Phi X was the first DNA genome to be sequenced ever" and that if it can be sequenced than much larger genomes can be as well.
In addition to the portable MinION, the company is developing a larger scale GridION for lab work that requires more processing horsepower. The sequencing technology in the MinION and GridION operate "like a tickertape reader" by unzipping the DNA using enzymes and electricity.
The article author states that the MinION and portable DNA sequencers like it are going to greatly enhance public health and medicine. When doctors will be able to carry around portable DNA sequencers, they will be able to quickly diagnose genetic issues and identify viruses and other pathogens. Sounds pretty cool (if a bit scary) to me!
