Get ready for summer with this water based USB fan. This is a small, portable fan houses a sponge so when air is drawing over it, cooler air comes out.
I’ve seen on the web some call this a portable air-conditioner, and I think that is unrealistic. However; if you want cooler air than what is in your office or room, this will do the trick.
I’ve read a couple of reviews from Amazon about the fan it people say it’s quite and does a good job of sending a stream of cool air.
You can run the fan directly from USB, or charge the battery for portable use. For example, on a hot summer day watching your kid play travel soccer or softball.
The USB water cooled fan comes in three different colors and is available now, before the heat of summer hits! At the time of this writing the USB fan was only $15. Almost a no-brain-er just as a try.

It could be said the top five topics for CES 2018 were robots, driverless cars, virtual reality, internet of things and drones; however, we should keep our eye on less flashy topics like our beloved USB.
We learned at CES the USB Implementer Forum is looking at the capability to increase data transfer rates up to 40Gbits/second. Translated into a more common term, that is about 5,000 MB/second.
It was reported Jeff Ravencraft, president of the USB Implementers Forum, was said this is a real possibility and the wiring currently used, is capable of such speeds.
Those who favor Thunderbolt because itâ€™s speed capability will no longer have a debatable advantage over USB, because once this new specification is released the speed between USB 3.x and Thunderbolt would be the same, maxing out at 40Gbps.
Itâ€™s always nice to appreciate our past before looking into the future. With that said, here is a chart of the USB ports currently available:
Using Windows 10, you can partition a USB flash drive into multiple partitions. The process is not difficult, you simply follow some easy steps. This tutorial will partition the drive so that your device is assigned multiple drive letters when connected to the computer.
This partition process is not done at the USB controller level; or said another way, done at the hardware level. This USB partition process, for a lack of better terms, is done at the software level. What does this mean for you? It means the partitions can be wiped off the drive and full capacity of the USB flash drive can be restored.
When a USB stick is partitioned at the controller level, or at the hardware level, there is no way to reverse the partition. The multi-partition drive is permanent. At the end of this tutorial is the solution for a hardware based partition solution.
So letâ€™s get started.
How to partition a USB flash drive in Windows 10:
Connect the USB flash drive to your Windows 10 machine. Be sure there is nothing valuable on the USB as this process will remove all content from the drive.
Right Click the Windows icon and select Disk Management.
The Disk Management window will appear with all the connected devices. Select your USB flash drive by clicking one time. By selecting your flash drive, it will allow Windows to apply the partition to that device.Continue Reading
I won’t claim to be a science expert, but found this article very interesting about a DNA Reader just a little larger than a USB drive.
For years, Illumina Technology has the lead in genome sequencing. Their gear is good and from what I understand their gear is expensive. The MinION (from Oxford Nanopore ) is an inexpensive alternative with some great upsides.
The DNA sequencer is just over $1,000 at the time of this post. Traditionally, a DNA sequencer could only read about 200 basis. A “basis” is a nucleobasis which is a collection of biologicial compounds that make up the basic building blocks of nucleic acid… or DNA.
The MinION is impressive with the ability to read 900,000 basis. Also called “long reads.” With the long reads you get a better idea of the compounds making up the DNA. Although the longer reads are not as accurate as short reads, the trade-off isn’t bad. The amount of time and effort to construct a long read from a collection of short reads is considerable. The less accurate long reads from MinION and not that far off base, thus a bit of a break through.
It is simply amazing that 15 years ago the human genome was a global effort, yet today it can be done in a device no larger than a flash drive.Continue Reading
If you’ve ever misplaced a phone or USB drive in your house and wished for a way to find it, a dog with a keen nose and a playful attitude could have helped you out. Fortunately, with skills like that, our canine friends are finding a much higher calling working with police, the FBI, and homeland security.
As devices improve, a tiny microSD the size of a fingernail and less than a millimeter thick can hold hundreds of gigabytes of data. With this advancement comes the tools for criminals to hide and transfer enormous amounts of information without even lifting a finger. Where does that leave the fine men and women tasked with staying one step ahead? In Ogden, Utah and across the United States, they are getting the edge with their friendly Labrador companions. Ogden is home to one of fewer than two dozen “Electronic Sniffing” dogs in the nation’s police force and his name is URL (pronounced “Earl”). URL sniffs out electronic media like flash drives, memory cards, and cell phones. While they’re not exactly cryptography experts, they are consistently able to find devices that humans might otherwise miss.
Starting around 2015 with a K-9 named Bear, investigations involving trafficking, pornography, and counterterrorism have had success with the sharp noses of the dogs alongside them. The dog’s expertise comes from playful, but rigorous training exercises and are on a food-reward diet. Dogs could be led to search an office piled to the ceiling with boxes, or an open field with evidence buried underground, and within minutes they will lead their handlers to the prize. What’s the secret? The common element between all these eletric devices is a circuitboard. Compounds are added to the board to help them deal with overheating and it’s this compound that officers train their K-9 partners with. Initially using large amounts and then all the way down to a standard thumb drive, the dogs familiarize the scent and the training to be able to search houses, vents, cars, and people if deemed necessary.
From detecting drugs, to explosives, and now to electronics, the utility of a canine’s senses can’t be understated. Craig Angle the co-director of the Canine Performance Sciences program at Auburn University said he’s seen dogs identify very small targets from incredible distances. “I’ve seen them detect two ounces of explosives from more than 300 yards away,” he said. “They can detect through barriers and masking agents. We see a lot of natural instincts in a dog’s ability to detect innate behaviors like understanding and utilizing wind currents and scent plume.” From a researcher perspective and from the law enforcement officers working with these animals, it’s clear that the full potential of cooperation like this has immense potential for evidence gathering in the future.Continue Reading
