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 an On/Off switch.  Oh..and of course all the step-by-step details to actually DO this USB hack. Cheers!
