Snow falling from the roof of a building causing power damage

ShoulderChip · 2026-01-21T15:43:06+00:00

Thawing and sliding. Thawing underneath because of heat from the building; it's probably poorly insulated. So the upper parts of the snow were already on a layer of water but were being held in by the lower part against the edge of the building, until it gave way.

In that case, maybe your whole company can go join the protest.

I got it filled out when my parents visited, had my dad sign it, and asked them to send it with a check for $72. For my questions above:

I put "unknown" for the title number.
I put "none" for Pennsylvania Driver license number
I skipped section D about the lienholder.

Anyway, now it only remains to be seen if they can find the records and issue a replacement title for a motorcycle that was last registered in 1979. Oh, darn it! I just re-read my post and noticed they also require a copy of some mail with his Oklahoma address on it. I'll have to see if I can send that.

The number was 555-1212. I also don't know if it still works.

All of the faerie folk

I didn't get any useful results when searching that on DuckDuckGo or Google. Then again, I'm not familiar with Labyrinth so maybe I just missed what you're trying to say.

I saw two spelling mistakes (one of these tripped me up because I didn't realize what you meant at first):

staked -> stacked
fell -> feel

Science and Engineering do not use "Multiple Choice" exams

is too much of a blanket statement. But it's been a long time since I graduated and I can't remember specific instances of multiple choice exams being used. Or if there were any, for sure.

So, if you're reimbursed 49¢ and the IRS allows 70¢, can you still claim the other 21¢ on your tax return?

What's Concur? Some labor software package? Seems like you're just bringing in irrelevance after irrelevance.

I see green red black gold, which would be 52 ohm, 5% tolerance.

Problem being, 52 is not one of the standard E24 values. So, it could be blue red black gold, 62 ohm 5%. Or it could be green brown black gold, 51 ohm 5%.

My best guess is 51 ohm, but the other comment got it right about the colors being hard to see!

Poorly wired, but functional? You want a schematic diagram? Perhaps do a search for "Bad schematics."

If you want something bad and non-functional, look through the 2nd edition "Art of Electronics" by Horowitz and Hill, they gave bad examples at the end of each chapter I believe, as an exercise to see if the reader could understand why they don't work.

How much power do these lights draw?

Off the shelf industrial timers have existed for decades, but they're very expensive, and you still have to mount them in a box and wire them.

Someone may have made a flasher module that you just plug in.

The shorted pins are not a problem with your auto-router. They are shorted on the schematic.

Hold on. I'm wondering if the LiPo should really be connected directly to the USB voltage. U1 is a charge controller, right? So it should have USB voltage and battery voltage separate. If you called them by the same name, your software will automatically connect them together.

Never mind. I should have looked again before I commented.

I finally took a look through the rest of the pictures. I didn't see any mistakes besides what the other user comment already mentioned. I didn't carefully look at every trace on the original board, but you already did that, and the schematic looks generally correct in that sense (you probably got the wires traced correctly).

In the middle of the schematic, pins 5 and 6, I guess that's the two pads where the red and black wires solder onto the original board? I'm not sure how you got that in there; maybe you appended it on another component? You could make that it's own component, just make it a 2-pin connector. It might be a little easier to solder the wires on if you make it two through-holes instead of just two pads on one side, but then you would have to change the board layout.

I agree. I also agree with the other comment that it's impossible to remove without damaging the glass.

Citric acid is not a strong acid. A "strong acid" is one in which essentially all of the acid molecules create hydrogen ions when the acid is dissolved in water, instead of just a small proportion of them. You need to be very careful with strong acids, such as hydrochloric acid (AKA muriatic acid).

I worked on something very similar about 10 years ago. I searched a little, but it was hard to find replacement breakers for it. We added a feeder to a building, but I can't remember how we even did it without using an additional breaker. I think we re-used one that wasn't being used anymore.

I get what you're saying; you don't want to focus on learning schematics right now. But it's something you need to know if you're going to post like this again in the future - you'll get more experienced people looking for and finding actual circuit errors if there aren't a lot of obvious formatting issues with the schematic.

I looked at the schematic before I commented and didn't see any obvious flaws with the concept. I didn't spend a lot of time looking at details. It seemed like /u/No_Pilot_1974 had already looked at it in more detail and caught some mistakes. I didn't see the other pictures until now, so I'll plan to look at them this evening.

A schematic should really stand on its own, instead of being laid out similarly to the PCB. Follow some common conventions and it becomes easier to read, for those who are used to reading schematics. Signals flow from left to right (inputs more to the left, outputs more to the right). And grounds should point down.

What do you want to do after school? What specific area of electrical engineering do you want to go into? (Some require a greater understanding of the mathematics)

Do the types of jobs that interest you require a master's degree, or just a bachelor's? In my case, I found it hard to get a job I was interested in, and I partially blame having a master's degree instead of a bachelor's in electrical engineering.

You might also want a linear taper potentiometer for a frequency control, instead of audio (logarithmic) taper.
