How To: Run LED Solo From PCless USB Connector

Do you see something odd about this picture?  Maybe the fact an LED is illuminating from a USB connector with no PC in site?  Ya that’s it.  Good job Sherlock.

So what we have here is a How To or USB Hack on running an LED from a Super-capacitor.  If you are non-technical, then we basically mean a very short lived battery to run the LED.  A super-capacitor has the ability to store energy for longer periods of time over traditional capacitors – yet still not long enough as with batteries.The concept of this tutorial is to wire a super-capacitor to a USB socket whereby your computer can charge up the capacitor and when disconnected you’ll get about 10 minutes of LED illumination.

Granted there isn’t much day-to-day use with this USB hack, but just a fun little project if you have the time. Over on the Instructables website there is an updated USB tutorial which includes Continue Reading

CoolerMaster Intro’s 95W USB Power Adapter Thats Universal

CoolerMaster is definitely taking advantage of the Universal Serial Bus we’ve all come to know as simply USB.  CoolerMaster introduces a universal power adapter which connects via USB.  The new USNA95 is a 95watt power block.  It can easily power your laptop, netbook and USB devices.

The USNA95 has a simple Red and Green LED to indicate whether a device is being power properly so even the tricky GPS units and SmartPhones will get the right amount of juice. The power cycle time is also faster for peripheral devices as CoolerMaster is stating a 30% faster cycle time to power your devices than a traditional device to PC connection. The USB power adapter is also the smallest one we’ve seen with a size of 62 x 17 x 104 mm and is texture surfaced to provide a durable case for when taken on the road.  Video after the jump Continue Reading

USB Hub – 13 Ports in 5 Inch Bay

Just last week GetUSB.info reported on a solar charging USB hub and a USB power strip and for noting more than to recharge your gadgets.  It’s clear that USB is the common thread in recharging – and moving forward I only expect this trend to continue.

Speaking of continue, now we have a 13 port USB hub which fits right into your 5.25″ computer bay.  I do say, the picture is inviting enough to get this add-on component and integrate it into your tower, but then we’ve got two questions for you.  1) Don’t most people use laptops these days and 2)  Imagine all the cables coming out of this thing.  I say this because you’ll quickly realize the ports are much too close for anything but cables.  Even the most slim USB stick would have a hard time fitting into each port.

What I do like about the design is the power connection you can make to the internal power supply of your PC.  This means the 13 port USB hub will support larger devices with more power thurst…say hard drives and large 64GB flash drives.

The 13 port hub isn’t on sale yet, but will be in late August 2010.  Pricing was not given.  Here is a link you can bookmark to check availability.

USB Solar Hub – So Close To What We Need

Yesterday we spoke about Elcom introducing a USB power strip and today we have USB Fever with a  solar powered USB hub.  We where very excited to hear about this product -  as it seems to be a step up from the introduction from yesterday, and it’s got some great features, but unfortunately, the solar power charging system isn’t for the USB devices which are connected, but rather the built-in LED torch light [insert sad face here].

USB solar charge Hub

I understand it would take a fairly big solar panel to correctly power 4-5 devices connected to a USB hub, but it would be nice to see a trickle charge feature for anything connected.  Like I said yesterday, in our house we have 3 iPhones, a Flip Video camera, two blue-tooth headsets and some other stuff, so a solar powered trickle charging USB hub would be nice.

They Took My Idea – USB Power Strip

About three weeks ago I started the process to design a USB power strip where the device would be a dumb down version of a USB hub…it only gives power.  The reason why I wanted to design something like this was for the infinite number of USB items I have.  Just in my house alone, we have 3 iPhones, one Flip Video camera and two blue-tooth headsets…all powered and recharged by USB. So enter, stage left, my thought of a USB power strip.  Well, Elcom was thinking the same thing, but only months earlier!  They have officially released the USB for port power strip and the 7 port USB power strip.  Clearly I think the idea is simply brilliant.

Elcom includes LED lights for each port to show if a device is active or not.  They include a switch to flip On or Off that particular port and last, Elcom gives you some clear labels [in English] to label what cable is going to which device.

The 4 port USB power strip is $40.  The 7 port USB power strip is $110.  Both are available at Geek Stuff 4 You.  Page. Continue Reading

Energy Boost for iPad – 99 Hours Worth

HyperMac updated their power blocks to include support for the iPad product line.  There are a couple models to chose from, but the high end, $500 unit, will give you 99 hours of iPad life.  More then enough for that weekend get-away. For a bit less, the $200 battery pack will get you the 60 watt version capable of powering your beloved Apple product for 34 hours. For this price, at least they include USB ports to power those USB gadgets you have in every corner of your office.
