I'm not sure this really justifies being called decapping, since the LED chips are just covered by a gel.

A brief respite from exploding hot dogs (very brief) to botch hot air soldering in a manner that will bring comfort to those of you who have done or have yet to do the same thing. I think the reason you don't see it happening in other people's videos is because they edit it out.

This alarm differs from a traditional smoke alarm by ignoring the smoke and looking for a sudden heat rise instead. That makes it better suited to kitchens and theatre environments where haze is used.
