A year ago, more or less, I gave my first try to a led strip and got that (luke ep VI MR for comparing) :

then I moved away from that to focus on luxeon technology and develop the module you know. A couple of week ago, some saw my iSaber thing on my telum infensus saber and said... whoa, that would be cool to have the animated bargraph... on the whole blade !
I thought it was time to rework on led strip. I used a stock MR blade that I've modified to get the best performance of it, and I forked the design of CrystalFocus V2.5 to make a led strip version. I took me 2 days to rework the electronic design and I spend parts of the WE to mod the software.

Same pic, with -2 points on the exposure to avoid saturation

And now, for something completely different... a little video. The ignition is slowed down in purpose, so that you can see the 2 combined effects, it's not a simple ignition of the led segments, it's the best combination of luxeon technology (fade in) plus the led stips segments.

Right now, the ignition time is mirrored on the duration of the sound, so it's not beautiful, but it works for the video. Don't I have to tell that I can have the proper ignition time and look by modifying a couple of line of code in the software. What is missing also is the constant brightness regulation. The curved is modelized but not implemented yet. It should maintain the brightness of the blade from 10 to 3.5V, roughtly. The blade is taking 2A right now, which the max of my home made PSU.
Enjoy !
