I wouldn't rely on the peel and stick backing though, but it's plastic so you can sink a couple screws in through the back. If you want something that's metal, there's also this: https://www.homedepot.com/p/Legrand-Wiremold-700-Series-10-ft-Metal-Surface-Raceway-Channel-in-White-700WH/100144606 The back slides out and you can use external clips to attach it to surfaces. It's also paintable, and has surface mount junction boxes available.

The metal looks interesting, I'll poke around to see if I can find one that snaps together, rather then slide together.

Nice. I actually got one of those acorn plugs for a project. They are.......not safe. Protected by a piece of cardboard on the bottom of them just like the olden days. Mine is "permanently" in a single outlet near the ceiling so it's fine.

When did these things get phased out? I've never seen one, I'm 37. Maybe they didn't come to Canada? Maybe by the time people lived on the west coast they were already gone? I don't know anything about this.

This seemed like the best thread but idk Our company is trying to buy an oscilloscope for general oscilloscope purposes, but we're not really electrical engineers. Which maker currently has the best network and usb access features? Our workflow would really work better if we have a good ability to interface with the device over network or usb, esp if there's an exposed API that is reasonable to work with.

This thread might be a little more on-topic for scope talk: https://forums.somethingawful.com/showthread.php?threadid=2734977 Or check out the eevblog test equipment forums: https://www.eevblog.com/forum/testgear/ Lastly, the one comment I'd have is if for any process reasons you're going to need to get the scopes calibrated periodically, you might want to check with local cal labs to make sure they'll work on whatever you pick and it won't cost extra for custom procedures.

Have a ceiling fan that suddenly started strobing if I run the light on; if I use one bulb of a 40w equivalent led bulb it works fine, but 2 or more and it starts strobing immediately as you turn it on, a 60w bulb does the same and 3 60w bulbs do not turn on at all. I have no reason to think the circuits overloaded, and nothing else seems affected. Is the likely cause loose connections in the fan head?

Are you trying to build a test stand (which usually means a remote controlled rack mounted scope behind a switch matrix), or are you looking for a bench scope (where good remote control is unusual because you are typically doing one offs and manually moving probes)?

Yes. A neutral came loose up in the head and the fan motor is running through the light bulb in series. Since you have an inductor and capacitor in series, they're effectively cancelling each other out.

Ewwwwwww… Windstorm on Christmas knocked out some of my driveway's outdoor lights (LED wallpacks)... and the motion sensors had stopped working for awhile, so I dove into it this past weekend since the replacements came in. (RAB WPLED10). Turns out the installers never sealed the tops of the poles where these are installed... ugh. Wet vac'd this out, but I'm not looking forward to going through 12 of the others, cleaning / drying and then resealing them. I spent a few hours labeling and tracing the wires to separate from the always-on, motion sensors, and so on. Further context (another post further down the driveway).  At least this seems to have been wired with California 3-way in mind... all the spare conductors needed to have two motion sensors in parallel, run some of the lights as pilots / always-on, and others off the sensors. I do have what I feel like is one 'leftover' wire though... I kept it as a neutral, but will sketch it out later and post here. movax fucked around with this message at 05:09 on Jan 27, 2023 |

I don't know if this belongs here or the general home thread, but it's electricity related so... Our garage has a light switch that controls a wall-mounted light socket:  It's the only light switch in the garage and there are no overhead lights out there. I'd like to run some brighter overhead lighting from it. Is there any reason that using a socket outlet like this: https://www.amazon.com/gp/product/B002DN6QX2/ To power a series of LED overhead lights like this: https://www.amazon.com/gp/product/B01HBT3BVM/ Is a bad idea? The listing says that they draw 20w of power, which is less than a 40w bulb (edit: as I was writing this I realized it says 20w per light and there are 6 lights, so that's maybe a problem). Is there more to consider than just watts used, or are those socket plugs a bad idea for some reason? I'm very ignorant about electrical stuff and I'd rather not burn down my garage.

incogneato posted:I don't know if this belongs here or the general home thread, but it's electricity related so... Watts are watts. A screw in socket is normally rated for 600w. 6 x 20w = 120w, one fifth the max rating of the fixture you're replacing. You're fine. I'd be more worried about the wiring in between. Look into wire molding. Take the socket off the wall and put a wire molding box extension/cover over the wall box to start the run up to the ceiling. If the circuit is 15 amps, use 14 gauge wire in the wire molding. If the circuit is 20 amps, use 12. Plan out wire mold path as best you can. You'll need at least one elbow at the wall/ceiling transition. Think of any other elbows and tees that you'll need. This is one of those projects where you should buy more pieces than you think you'll need, then return everything that you ended up not using. That includes wire. If you're going to be running 2 strings of lights at 3 each, get enough wire to run into the closest string, then from there back to the tee to the farther string. You can put wire mold boxes on the ceiling with regular outlets in them. kid sinister fucked around with this message at 23:39 on Jan 29, 2023 |

I'd be curious to hear the NEC reasoning against it, if any, (outside of the usual motivation of stop idiots from stringing extension cords and causing fires). NEMA 14-15 receptacles exist, though now that I think about it, I don't see those plugs super often... Though, for kind of lab usage, some kind of variable AC source is usually really nice, or an inverter-based setup. Key feature being current-limiting and fault-tolerance, if you're testing directly 220/240V driven hardware -- nice to have something besides a regular breaker protecting that. e: vv yes, Variac movax fucked around with this message at 21:56 on Jan 31, 2023 |

That's a valid reason to want to install one then, but like others have said variacs are also useful for that and offer better protection for a test bench. The first question for wanting to do anything that isn't the regional standard with power, even if it's permitted by code, is "why" and "can this be accomplished in a way that is not non-standard." Otherwise you might end up like Grover installing receptacles in his ceiling.

Spend your time and money on a good variac vs pulling oddball wire. Though I would totally run my computer off it if someone else had installed it in my house because it would amuse me.

If you want a recommendation for a variac, you should probably ask in the electronics thread here in DIY. They would probably know better than electricians.
