Maker Monday: Electric Umbrella

[Charles] It took me quite a few articles and digs to end up on an Electric Umbrella, but well here it is. I wasn't looking for it and that made it much more intriguing of course. I actually was just wondering how to make an LED light bulb. I dug into Google and Make magazine and Instructables and read quite a bit about LED reading lamps and flashlight circuits. It sounds pretty simple really - you get some LEDs and resistors and a DC power source and wire it up. Of course there are some simple calculations about getting the resistors right and well you have to keep in mind that LEDs are electrically directional. It doesn't sound too bad though. I still didn't find a lightbulb exactly but this umbrella is pretty cool and it might be just the thing for long walks home in a neighborhood that isn't too pedestrian friendly...
