OCD much?

Even worse, when I'm putting the finishing plate on outlet and switch around the house the screw slots ALWAYS have to be DEAD VERTICAL even if it means slightly loose or too tight.
I didn't get that one at all. What are you referring to?
IDK bout Greece, but in 'merica, lightswitch plates and outlet plates are attached to the wall with flat head screws
like dis-


And yea, I always have to have them vertical or horizontal, the same throughout the room. No different directions. Bad. Dislike.

OMG, now I know what OCD means! Do you guys make sure the resistors are soldered in the right way? Or the toilet paper hangs in front or behind?
Tolerance band has to be on the right, chips have to point towards the left, and the toilet paper has to hang in front :D

Heres a question for the people on the other side of the world. Does the toilet really swirl the opposite direction on opposite sides of the world?

I don't care for resistor direction, but toilet paper must DEFINITELY hang from the front.

I think that the toilet swirl is a north-south hemisphere thing, so I can't answer that. May Rifaa has something to say. But wasn't it about the bathtub swirl actually?

Yes, the toilet water swirl is a north/south thing. It has to do with the direction the earth is spinning. Looking at the north pole, the earth spins clockwise, which means that the water spins down the drain in a clockwise direction. From the point of view of the south pole, the earth is spinning in a counter-clockwise direction, which makes the water swirl in a counter-clockwise direction. Pure physics :D

This is incorrect on two counts.

Looking at the north pole from above, the earth spins counter-clockwise.

The belief that the water goes down the drain in a direction dictated by Coriolis forces is an urban myth. The Coriolis forces at the bath tub or toilet bowl are too small. The direction of the swirl is determine by the shape of the bowl and other physical items in the bowl.

Thanks for the correction, MrChips. I just did a little research and you're absolutely right. I suppose next time I should research before I just rattle off what I've heard in the past :p

Kind regards

The marking on any part should be visible for inspection. Period. Genmerally, all parts should go in with the same orientaion. However, if need be parts can be orientated differently to prevent marking from being obscured by other components.

That is actually a general rule for several companies I have worked for, and it has special applicability when a government inspector comes in to inspect an assembly for workmanship and anything else he feels like.

For SMD resistors I don't like to go below 0805 size, as that is the smallest to still have a value printed on the part. Of course the markings are all orientated the same way.

SMD caps never have their value printed, so if possible get a different case size for every value you use. A very experienced engineer taught me that one, it makes it harder (not impossible) for production to make a mistake.

(What are resistor bands? I haven't used those in ages.)

TP hangs over the front so you can find the end. The other way may be easier to rip for those us us who stand up to clean up after we've shat, but first you have to find it.

very clever, I'm going to remember that one :)

I go neither left nor right. I go straight.

Reminds me of a joke someone told me years ago. Remember the years when consumer electronics moved into miniaturized packaging? My friend told me the difference between American and Japanese resistor placement on PCBs. Americans do it laying down while the Japanese prefer it standing up.

Good one :)
but if their standing up, where should the tolerance band be? on top or the bottom?
