I'll look around, that sounds perfect.

Hey I get it. Others quoted much higher so I jumped at 65 a light. He didnt ask if it was blown or not. I assumed someone doing it professionally would know to ask or just know what to expect. It's not as if I misled him.

A ton of blown in insulation can, and will fall out during the process, unless you clear it well away from each hole. Add to that the hazards of working in a hazardous space, and it really isnt worth doing for $65.

Take a look at this. It has a built in focusable projector and all you need to do is put in a card with media. I have a bigger version and the projector works pretty cool. It doesn't have a lot of light output but with your short throw it might be perfect. However, you might need to experiment with some additional lensing to get the image to the right size. You can also use neutral density gels/filters to reduce the light on such a compact area. Definitely doable.

In residential it's rare. On utility sites it's used quite commonly for power and comms between settings and buildings. We only use stranded for that because there may be lots of bends in the conduit from point A to B. Specifically where it has to be in conduit and in Class 1 Div II areas.

No, but it was very small. A pocket projector, I think it was called. Black box, about 3 inches long and one inch wide. I was pretty fond of Black Web at the time, so maybe one of theirs... I think I paid about $100 for it at the time...

It would go inside a box, approx 30" x 30" x 30". I would like to project onto a piece of textured white paper or white cloth. I don't have the all the details determined yet; this is just a germ of an idea at this point.

If there is a tiny projector that can focus within 3' or so, with a very small image, I might buy it and then experiment.

We make houses out of solid brick, or brick that, while hollow, you can't pass wires through. The wall is built, then a channel for the plastic conduit is carved into it.

This is standard: https://i.imgur.com/rZdWBD9.png

Will do, thanks.

Thanks; do you remember which model it was?

Thanks.

I'll take a look, thanks!

A half bushel per league on a good day. Auto correct favors juice over juice apparently.

Yeah, nothing you're saying is wrong at all, but you're gonna get pushback just based on the nature of this subreddit.

Tuff Shed is a perfectly reputable company and OP himself said he bought lumber from the same stores the person you're replying to claims is garbage lol. And if the integrity of the build is all you're worried about with a pre-built one you could just spend a fraction of the money on reinforcing, insulating, and getting better siding.

I totally get the argument that DIY is great invaluable experience, that's fine, but there's no point pretending that projects like this aren't WAY more expensive to do yourself.

In most construction, wiring now goes in the cavity in walls.

In some places like the UK, wiring can be direclty rendered in the wall.

Skin effect utterly meaningless at low voltages in domestic and industrial systems. It is only significant in very high voltage long distance reticulation.

Yeah, that's more or less what I was trying to say. Not that the skin depth is different, but the way it's distributed in space is different in stranded, especially at higher frequency. E.g. http://www.bdloops.com/solid_vs_stranded_loop_wire.html

Yeah, and I encountered work by qualified electricians where somebody forgot to tighten a screw too.

hahaha

skin depth is a function of frequency, not cross sectional area.

the reason stranded conductors have higher impedance at the same guage is because they have a smaller cross sectional area.

to illustrate: a pile of smaller circles can never completely fill a circle.

In the US, we pretty much only use solid wire (Romex) in residential

ok, say you guys give him good advice, doesn’t mean he’s going to do it correctly. I just left a customer’s house, the guy wired up his outlets himself, says he’s done it hundreds of times but for some reason half the room isn’t working. I went to the first outlet, he hadn’t tightened a screw correctly and the wire was just sitting there and heating up because of the bad connection. He was risking a house fire because he didn’t do a “simple” outlet correctly.

Solid core, while less flexible, has a lower surface area. Firstly, this makes them more resistant to corrosion. Second, they have a lower "dissipation", or voltage drop for a given length, as the skin effect in multiple strands increases impedance. Overall, this makes solid core less likely to fail and cause fires in static applications like home wiring.
