So I been looking for something to do in my downtime. See, I'm in the Navy. Once a week, I have duty, and I have to stay on the boat overnight. So I got a lot of time to kill, and wanted something to fill it. Making bright shiny things with LEDs sounded like a good idea.
So I set out on ebay and bought the first brightish looking LED I could find. These for example. Then I googled to find out what I was doing, found this here calculator, and set out to make something.
This is the result (image). [Note, I linked to the image because it's 5MP and I was too lazy to shrink it before I uploaded it]. Man, this thing was bright. So I set it on my window ledge and took a shot with my crappy camera. Here's the shot (image).
It's pretty simply made. Four 9V batteries hooked in series for 36V total. And then 5 rows of 10 LEDs with a 1 Ohm resistor at the end, all hooked up in parallel to the batteries. And a switch thrown in on the negative side.
I just called it The Pretender because I like to pretend like I know what I'm doing, even though it feels like I don't. But I made all this before I even heard about this place. So now I have some reading up to do and then I can reuse those LEDs for my next idear.
