I've been looking at doing a string blade for a couple of months now. I don't entirely understand how the electrical part works yet, but that's part of what this process is about.
I found some straw hat LEDs on Amazon that have a nearly 180 degree viewing angle. Since the light is shining out instead of just up, it should maximize blade effect.
I got some cheap little 3mm LEDs at my local electronics supply store to practice the bending technique. As you can see on the first couple of LEDs, my technique wasn't so good, but starts to become more consistent towards the bottom. I put a dot of solder at each joint and cut off the extra leg length. Is it recommended to keep the extra length of leg? I just figured they would get in the way, so I trimmed them.
I'm not sure how the resistance math will work, so I just put a beefy 2 watt resistor on there to keep things from burning out. If anyone can help me with how the resistor math works with string blades, it would be much appreciated.
