I asked: May comments be used to answer old unanswered questions?
One moderator says yes and the another moderator said no on the old questions answered this way. Should I listen to the moderator with a higher rep.?
Side Question? Is it better to have a half answer then no answer to lower unanswered questions?
Your answers are old comments repeated verbatim. I'll show these answers here for folks who don't have the 10k visibility yet.
from here [since it provides context for this meta, I'm not going to delete that just yet] :
The voltage across each depends on how much current each needs to operate. If one has a resistance equivalent to 10 Ohms and the other a resistance equivalent to 100Ohms then you will have a voltage divider such that there is 10 times more voltage across the larger resistance. Just use a 5V regulator to power both devices. – JRE Jan 7 '17 at 8:51
Your margins are too small if the absolute maximum rating of a component is 5V then supplying it with 5V is asking for trouble. Any supply deviation (spikes, noise) can result in failure. Then we get into how the voltage is shared between the components to answer that we need to know what they are and how they are being operated. – RoyC Jan 7 '17 at 10:28
Use two TL431 shunt regulators. One in parallel with each element.
These should be made an answer. May comments be used to answer old unanswered questions?
from here:
If the speed control works somewhat, the basic design and assembly is probably OK, but there is a problem with connections and/or noise. Lack of isolation between the mains and the control circuitry is always a risk. The main current path for the motor current shown as two of 8 ground symbols is also suspect. – Charles Cowie Dec 15 '16 at 12:28

Elliott, I am too young to relate with incandescent light bulbs. Yes, I guess that's a good example of circuits at different temperatures! No light emission required tho, just softening metal plates for clay mold covering. Yes indeed Uwe, it would be another DIY. Thanks, Peter I've found this question electronics.stackexchange.com/questions/350145/… that has "use copper attached to steel bonded to nichrome" as an accepted answer. – Gaston Jul 2 '18 at 19:48
The information is already there in the form of comments. Stapling comments together and posting that as an answer duplicates information. It doesn't contribute new knowledge.
There's a general rule across SE sites that if someone posts an answer as a comment, it's fair game to turn that into an answer. I think there's even a blog post by Jeff Atwood (SE co-founder) saying it's fine.
However, the examples of what you did that Nick Alexeev posted are a terrible way to do it. If you understand a question and answer well enough to turn the comment(s) into a full-blown answer, I'd say that's fine. But simply copying a few different comments into the answer box isn't useful at all. They might be components of a complete answer, but the examples are pretty much incoherent.
