comment Can I run heat tape on my water pipe behind drywall without hardwiring?
Why do you even need the heat tape -- is the basement unconditioned? Seems very strange that you'd have drywall up if that's the case. Generally a basement would have the exterior walls insulated, either have HVAC vents (though perhaps not as open as the rest of the house) or have radiators/other heat source. Especially if the floor between basement and main floor is uninsulated, there will be a lot of heat loss and it will be noticeably cold on people's feet (even if the ambient air temperate is otherwise ok, generally this will cause people to still feel cold).

comment Should I expect a level ceiling when my kitchen was completely gutted?
"Change the ceiling joists"?? Yikes.. That is a pretty major structure modification, which could easily double the cost of a typical kitchen reno. The typical way to level a ceiling is with strapping and shims, which would easily take under a day for the average kitchen, and not involve any structural engineers..

comment What is the best way to run underground electrical and low voltage in the same trench?
You should also bury some underground marking tape a few inches below grade. This is so if someone digs they will find the warning tape before they find the conduit/wire.

comment How to remove wires from doorbell
I assume that you don't intend to replace the door bell? And that "look good" is a relative term, considering it was mounted on a piece of crappy-looking weathered plywood?

comment How to control a dimmable LED light?
It's not that it won't work, per se, but it's that the wires (traces) in the strip itself are only rated for a certain current.. get beyond that, and it will heat up too much. This can lead to something from nothing happening, to the LEDs lifetime being shortened, to the strip actually failing, to starting a fire. This is really no different from regular household wiring, and the reason we don't use 14/2 for dryers and stoves, for example.

comment How to control a dimmable LED light?
Most of the strips I've seen actually have a limit on the total current they can handle, and so only allow you to chain power for a few strips at a time. You'd need to run separate wires for each set of segments you need; whether you power them with one or multiple transformers is your call. There are different wiring requirements depending on the types of LEDs you're using (individually addressable or not; white vs RGB vs RGBW), so you'll need to figure some of that out before you start.

comment How should I run wiring for my above-fireplace mounted TV?
It's also worth pointing out that hanging a fireplace above a TV isn't a great idea: the TV can be harmed by the heat; it's hard on your neck; and the image quality can suffer because of off-axis viewing. The best height to put a TV at is eye level when sitting. But don't just take my word for it.

comment HoneyWell Wifi Thermostat and C wire
You'll likely find the answer if you look at other thermostat-c-wire questions. To get a specific answer, you'll have to take a picture of both ends of the wire, showing the labelled terminals on the furnace/air handler as well as the thermostat itself. Wire colors are not actually standardized and so you can't make assumptions, and usually HVAC installers don't connect the C-wire at the furnace unless it's actually needed.

Are there other switches/wires in this box? A labelled picture may help here.

comment How to use fiber optics to illuminate glass tiles?
LED strips commonly have IP ratings: IP67 is rated for immersion in up to 1m of water for 30 minutes, IP68 is rated for >1m indefinitely. You'd have to separately deal with the electrical connections (ensuring they are IP67 rated or equivalent as well). Sounds like an interesting way to do it.

comment What factors are important when selecting a rotary tool?
Yes, "right tool for the job" is a key phrase here. For example, I would never try cutting PVC pipe with a rotary power tool. It would take longer than other options, and be nearly impossible to get a flat, straight cut. I would use a pipe cutting tool, hacksaw or straight saw in a mitre box, or a (power) mitre or chop saw, depending on what's handy, the size and thickness of pipe, and how many cuts I have to make.
