Essential maker skills

Uptown Maker's "18 Essential Skills for a Maker" is a damned good list; reminds me of Heinlein's "A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects."
2. Spot valuable salvage- Not only knowing where to get it, but knowing it when you see it. Finding it isn't too hard- curbs, alleys, and the classic dumpster dive. Deciding whether to keep it is the real trick: can it be broken down? Are there useful things inside (gears, motors, electronics, hardware, salvageable wood, springs, etc.)? Is trying to salvage parts of it a wise thing to do (upholstered items left outside are a great way to get bedbugs into your home)?

3. Spot eminently hackable, cheap Chinese crap- The glut of crap from China occasionally brings some real gems with it. Woot.com recently sold some rotating LED-based "police lights" for $3, which connect to USB and can be turned on and off by pressing a key on the keyboard...

7. Know which glue to use, when- Elmer's white, spray mount, Uhu glue sticks, JB Weld, cyanoacrylate, and two-part epoxy all have their uses.

8. Know which tape to use, when- Duct, masking, Scotch, foam-two-sided, and (occasionally) electrical tape all have their uses...

14. Create fairly neat holes of arbitrary size and shape in sheet metal, plastic, and wood- Nibblers, step-bits, tin-snips, chisels, awls, drill bits, and the appropriate Dremel bit all play crucuial roles here...
