I know it's only partially relevant here, but I was wondering maybe I should start learning to solder. Could be a useful skill for many things, including keyboards. However I have no clue about electronics except I heard of amper, voltage, watts and I barely remember what resistance does from school.
I looked at some soldering irons / stations and there's a wide variety, from 10 to 100 watt, and from (europe) 230v to lower voltage ones...
How does one make sense for it? What value should I aim for, in a soldering iron, let's say concerning pcbs/keyboards? In some situations lower power might not be enough, higher might burn stuff. Are these always configurable, like 50w means it can do 50 and lower?
If one wants to be able to desolder at some point (I think inevitable if we talk about keyboards, at some point one may want to change switches or whatnot), is there any special requirement for that in a soldering iron?
I know some of these can be had for very cheap on the other hand some people say don't even bother doing any good work with cheapest ones especially desoldering. Any truth to that? Is this a 100$ ticket really or it's just a slight exaggeration? I think an important question unless one does any serious work at least few hours a week...
