The portable LED USB multimeter (that you didn’t know you needed)

Update 08/01/2016: If you’re looking for full-size multimeters with USB support. There’s a new article on budget DMMs. Of which 2 DMMs have USB data connection support.

The USB port is one of those things in the 21st century that provides the necessary “lifeblood” (electricity) to charge and re-charge all of our fancy cellphones and gadgets. Yet rarely in this process is there a good way to know that things are going well in the power transfer process. Maybe you’ve experienced plugging in your phone to charge and yet for some reason it doesn’t appear to take a charge or perhaps it’s just charging too slowly. And how does one figure out what to do about this? Surely, there is a little gizmo that can help us out here!

And sure enough, there is. In fact, there’s more than just one. There’s a whole bunch of them. They go by the names “charger doctor”, “USB detector”, “USB meter”, and even “USB power monitor”. At the end of the day, they’re mostly just digital multimeters designed for the USB port, but what they do is insightful!

And the best part is that they sell for under $15.

Adding a 1TB Seagate Backup Plus Slim HDD to my Wii U (or: How I hacked a USB 2.0 cable.)

The last article I wrote about was a review of 1TB portable USB 3.0 hard drives. During this review, I tested each drive with a variety of computers and other devices that had USB ports, including my Nintendo Wii and Wii U consoles. Part of this review was trying to answer the question of “Which is the best hard drive for the Nintendo Wii U?” — which I couldn’t definitively answer. I found that all of these slim 1TB drives worked just fine with the old Nintendo Wii (the previous generation console), but only 1 of them worked with the Wii U (the most current Nintendo console.)

1TB Portable USB 3.0 HDD review: WD My Passport Ultra -vs- Seagate Backup Plus Slim -vs- Toshiba -vs- HGST -vs- Samsung

It is this author’s opinion that 2015 should be the ‘Year of the Backup’. It is 2015 and almost no one takes backups. And even those of us who do take backups, well, we don’t do it often enough.

Originally the problem of backing up was not having a reliable, yet automated program. (Much less an easy way to restore a backup, if needed.) But Windows 7 has a good backup system now and Windows 8 has an even better one. And Mac OS X has had its excellent TimeMachine feature for quite a while now. So these are now non-issues. This leaves only one question: Where to back up to?

Tape drives were never a good choice for consumers, CD-Rs and DVD+Rs were too small and too slow. And until recently, most external hard drives were big, bulky, and required a power brick to be plugged in just to run them. Oh, and they were somewhat slow running over the USB 2.0 port.

Update 15-Feb-2015! Two new drives have been added to the review: The HGST Touro Mobile vs the Samsung P3 Portable.

For this review, we picked out a portable USB 3.0 hard drive from 5 major manufacturers, WD, Seagate, Toshiba, HGST, and Samsung and put each drive through its paces.
