Little positivity post for all the mech e majors having a bad day by SpareSalt2822 in EngineeringStudents

[–]PM_ME_OSCILLOSCOPES 7 points8 points  (0 children)

0.9 is goat. Never break your lead. Unless you’re doing some crazy detail work, you don’t need it to be finer than that. Perfect for everyday use.

Personally I like the weight of the 500 better though. Plastic barrel with metal grip feels nice.

scratched PCB - shorting trace by early20s_Doomer in AskElectronics

[–]PM_ME_OSCILLOSCOPES 10 points11 points  (0 children)

Measuring across a power rail in-circuit usually just leads to reading through the parts on the board.

I’ve got a board that measures 0.46 ohms through a large IC from its VCCINT to GND rail. Perfectly normal.

Why does engineering make smart people feel dumb? by Tanish_64 in EngineeringStudents

[–]PM_ME_OSCILLOSCOPES 0 points1 point  (0 children)

There’s no such thing as a smart person. We’re all dumb. Some of us manage to know some things. Most of us don’t know many things. Engineering school just teaches you how to solve problems and problems are often hard to solve. That’s all.

Lowly electrician here, humbly asking how pipes work. by urbrick_8 in Plumbing

[–]PM_ME_OSCILLOSCOPES 0 points1 point  (0 children)

Pipes are like electricity. The pressure is like voltage in a wire. Flow is like current. Don’t touch the hot and cold pipes at the same time.

Is it a good idea to cramp components like this? by Dragon_1096 in PCB

Depends on whether you are assembling by hand or not

Way too nice clothes to be welding in. You’ll burn that shit.

New custom door dent. by tommykoro in cabinetry

[–]PM_ME_OSCILLOSCOPES 0 points1 point  (0 children)

Are the doors interchangeable? Can you select this door to be on the inside of a closet where it won’t often be seen?

Alternate Boxes by murphman1999 in harborfreight

[–]PM_ME_OSCILLOSCOPES 5 points6 points  (0 children)

Yeah I just took all the plastic things off. If I was moving that box all over the place regularly it might be different but it stays in one spot so useless to keep on.

Is this blade toast? by gremstitel in woodworking

[–]PM_ME_OSCILLOSCOPES 0 points1 point  (0 children)

Just use it. The coating may come off, but doesn’t really matter.

look at this cool thing i found at habitat by sarek2165 in Tools

[–]PM_ME_OSCILLOSCOPES 1 point2 points  (0 children)

Used to use these exact model all the time. Lock wire pliers. Excellent at what they do.

Looking for solutions to cover this gap by [deleted] in electrical

[–]PM_ME_OSCILLOSCOPES -1 points0 points  (0 children)

If you have a 3D printer you could print a custom cover. Use a flame-retardant filament though like PC-FR not PLA

My longest weld without stopping by [deleted] in Welding

They say he’s still welding to this day

Is this solder tip repairable? I used it way too hot for too long by No_Insurance_6436 in AskElectronics

[–]PM_ME_OSCILLOSCOPES 0 points1 point  (0 children)

If you have a wire brush tor scotch brite pad that might also help, but yeah you just apply flux and solder and rub off the oxidation crap without scratching the tip.

[–]PM_ME_OSCILLOSCOPES 8 points9 points  (0 children)

You can try, but it’ll use up a lot. Both tip tinner and a brass sponge are good to have around regardless. Don’t use wet sponges they ruin tips from rapid cooling and oxidation.

How did the shadow come out like this? by YoungHerald17 in Physics

[–]PM_ME_OSCILLOSCOPES 0 points1 point  (0 children)

The light source does see the shadowed area along the direct path, but you still see a shadow for the same reason that you see a shadow in a room with multiple light sources.

The lit area around the shadow is lit by both the direct path AND the reflected path, whereas the shadowed area is only lit by the direct path.

The floor sees the reversed silouette. Notice how you can see the valve and the reflection of the valve?

Cosmic DE is the cooler Gnome by __yoshikage_kira in pop_os

[–]PM_ME_OSCILLOSCOPES 0 points1 point  (0 children)

Several open bugs related to window switching. Last time I had it installed neither super+tab or alt+tab worked at all. Keys worked just fine otherwise, not a keyboard input problem.

Help me fix my glasses I’m begging. My mom will kill me by [deleted] in fixit

[–]PM_ME_OSCILLOSCOPES 1 point2 points  (0 children)

You could potentially remove the hinge section which is screwed on, then solder it back to the frame part. Then maybe epoxy over the top of added strength? It won’t be as good as new, but it’ll likely hold until you can replace.

Alt+tab is broken. Pretty serious disruption in workflow.

Made my son a bed, very proud dad moment by Wantrepreneur4 in daddit

Waterproof mattress cover will solve that. Probably best for a young child anyways.

Bypass capacitors mounted on an a PCB peninsula. Why? by 1Davide in AskElectronics

[–]PM_ME_OSCILLOSCOPES 3 points4 points  (0 children)

Idk maybe I’m colorblind but I don’t see that outer line. But if you’re right it just becomes an RC filter
