what's REALLY fascinating is to try and figure out the failure process: 1. LED die continues to light, but the current is quite high and it heats up 2. the bond wire heats up and glows (you can see the light shift downward in the video slightly)
3. pressure builds up inside, the softened plastic starts to bulge out of the bottom 4. catastrophic failure! the plastic shears along lines of stress created when the plastic was originally molded.
How do you get these great cuts. Are you cutting or grinding? Looks really great!
For this one, look at the preceding tweet :)
