December 1, 2011: I have done similar projects before, but this is the first one that I actually took pictures of. I opted to use the on off switch, just because they added a resistor in there and I wasn't sure too sure why (see picture below with the mystery resistor). The specs on the package say 4.5VDC at 0.68W, using 3-C size batteries. Well, after forgetting to turn it off one evening when I left work, I decided something must be done. C batteries aren't cheap and don't grow on trees. Since USB operates at 5VDC, I figured, why not!
This little mini-mod took me all of about 15 minutes to do, minus clean up.
Parts:Model 62-979AB, 30 Count LED teeny Light Set. I got mine at my local WalMart. I think they were under $8 or so. I really wasn't paying much attention... Ohhh... LEDs... Sparkly!
Tools: Dremel® (Check out their website) or any type of rotary tool, and a cutting bit or a drill. And of course, a soldering iron. I also used my trusty hot melt glue gun.
