comment If DC adapters are so prevalent, why is AC used in construction by default?
The safety disclaimer is bad and should be deleted. This site should be home of useful information, not bogus, false claims. If every false claim wasn't eliminated and silly "disclaimers" were left, this site would rapidly decrease in usefulness.

comment Diy raspberry pi
It plays a small role in home automation compared to the many existing commercial products. In any case, the answer to your question is: learn the entirety of the Electrical Engineering profession. Your question is analogous to "I would like to know how to create a diy Chevy Malibu like the Ford focus clone." The work involved requires many years of skill development.

comment Wood that can be easily bent
To my knowledge, veneers are sufficiently bendy because they are so thin (usually about 1/64"), that its rarely an issue to make a curve.

comment Can mortise and tenon joints be strong without glue?
The loft bed in that other question looks dodgy, even if glued/screwed together, with no cross bracing on the legs.

comment The right-handed (RH) thread vs the left-handed (RH) thread in screws
Generally speaking, every screw you will encounter or should use in a "household" context will be RH threaded. I've only used LH screws in automotive/bicycle/industrial machinery type situations.

comment How do I pre-wire for in-ceiling speakers and give a clean finished look without installing speakers for several months?
Why not just tape the wires to the joists near where the speakers will be, and just drywall over it. When you're ready to install the speakers, cut the holes and grab the wires out from where they are waiting?

comment How to drill a grommet hole through a desk?
Also, when using a hole saw, run it in reverse initially to cleanly go through the veneered surface, before going the right direction to cut through the meat of the desk surface.

It would depend on the half-life of your waste whether it would be worthwhile or not.

comment How can I block off my stairs while I repair the walls?
Since it's only for a couple of days, would it work to just block off all the surrounding rooms rather than the staircase itself?

comment How can I tighten a bolt in a circular hole?
@Urbycoz: every respectable hardware store will sell socket wrench kits. Ask a staff guy for ratchets and sockets and he'll be able to direct you.

comment How can I get rid of a mouse in my house?
I think you'd probably want a CO2 or one of the lesser pellet rifles for mice. A good break-barrel pellet rifle is effective for dispatching squirrels, and rabbits if you're a good shot, but would probably be a bit much for a mouse.

comment Is it possible to make a heliostat with no moving parts?
All this is doing is increasing the square footage of mirror you are using to compensate for lack of motion.
