There are also LEDs with a built-in "candle flicker" effect. This teardown shows how it's done with two dies integrate into the LED package: the LED and an ASIC. They also demo a circuit using a small flicker LED and an amplifier to control a much larger LED.

Fuck Donald Trump and all his cronies.
Now explain PartialEq, and why it's mandatory.
I went to the LA showing of "To The Journey", a crowdfunded documentary about the making of Star Trek: Voyager.
Several cast and crew were there, including Rick Berman, Robert Picardo, Tim Russ, and Garrett Wang.
The cost isn't necessarily zero. Old games are often removed due to music licenses that are about to expire.
Lead-based solder is preferred for high-reliability electronics (space, nuclear, military, etc.) because it's easier to rework, easier to verify by visual inspection, and it's not vulnerable to tin whiskers.
Here's the relevant safety guides from Stanford and MIT.
In short, if you do a lot of soldering, there are long-term occupational hazards from both lead oxides and rosin. Both guides agree that the main hazards are the fumes (workstation should have a fume extractor or suitable filter) and residue on your hands (wash hands with soap and water before eating).
I couldn't find any numbers on how much material is removed by washing, but every reference emphasized that soap and water are vitally important.
