Shop27vt of Instructables.com is a professional remodeler who's constantly on the lookout for ways to upcycle his old scrap metal and turn them into beautiful and functional household utilities. I'm personally a huge fan of his rustic/steampunk aesthetic that I'm sure you won't want to miss.
I'ma go out on a limb here, and say that knowing how to solder is an essential skill for any creative person. Make no mistake: I know nothing about capacitors and breadboards, nor programming or arduinos. In fact, part of the reason I founded ManMade was to complement that version of the maker/hacker website by bringing in less tech-heavy approaches to creativity.
But, regardless of whether or not I'm ever gonna build a robot (I'm not), I think knowing how to solder is super important for DIY projects. Making a lamp from plumbing pipes really benefits from knowing your wires are gonna stay together inside the thing; just this weekend, I retrieved my first "grownup" instrument - a Peavey Fury bass guitar in all its 1994 red/white glory - from a family member who'd borrowed it years ago, thinking it broken, and I fixed it just by soldering some ground wires that had come loose.
It is, as this free downloable comic book from Andie's Log states, easy.
For many creative men, "making things" often includes circuit boards, LEDs, microcontrollers, and the like. And while ManMade always argues that men should be encouraged to use their yarn skeins just as often as their soldering iron, it's still important to know how to actually use that soldering iron safely and effectively.
Enter the Ten Commandments of Soldering, a collection of Thous and Shalls for the wire connecting crowd. Even if you don't know how to solder, or what it actually does, it's a worthwhile read.
