That would work. A bit wobbly during a storm though because buildings are wood frame out here. But in Denmark it should perform nicely.

a storm big enough to wobble the house and you would be thinking about a microscope?

yeh you are right here we build houses of bricks, wood is for sheds and garages :P

Oh, we work through that out here. Just like I do not give up on plans for a barbecue session because it hails or when there are gale force winds. Then I just tie down the barbie and secure the lid with wire. When the wind howls things cook really fast in there.

Brick houses tend to crack or collapse in earthquakes and we have a lot of those.

BTW, the brick house I lived in while in the Netherlands rocked very noticeable when a strom blew through from the west.

Strange with all the space Americans build where there is regular earthquakes, hurricanes, flooding or a bit of everything

I might hear things in the kitchen rattle when a big heavy truck drives past but wind doesn't do anything, I live close to the harbor so the foundation is probably on old mud I'd guess much of the Netherlands is similar

Parsing error. It's earthquakes they have a lot of in CA, not brick houses. The prevalence of the one is one reason for the scarcity of the other. We have a lot of trees, you guys have a lot of mud. ;)

Here's the pick-and-place that we use for a little inductor...

We have lots of wood here. In the 1989 earthquake, it was brick buildings that collapsed and killed people (well, the Oakland elevated freeway, too.) Right next to our business, all the bricks on the face of a 6-story apartment building peeled off and hit the sidewalk. Miraculously, nobody was hit. One brick would have killed you.

I can't imagine what would happen if an earthquake hit a big pile-o-rocks city like Boston or London or Paris.

We like to live on the egde :-)

Sometimes a whole lot:

If you took a map of the US and marked out all of the areas where the above natural disasters are prevalent (add tornados), you would be left with maybe a square mile for the 350M people to live. ...and that would be a desert. ;-)

The wind doesn't "do anything" to a wood-framed house, either. ...within reason.

Here's the pick-and-place machine for slightly larger magnetics:

My old P&P machine probably can't do 0402 well at all. I think it can do 0603, but haven't tried it. The stuff I do is VERY pedestrian stuff, as long as I can get these parts, there's no need to push to smaller parts.

Small buildings (and everything inside) would be gone. The skyscrapers (over 20ish stories) would likely survive quite well. IOW, it wouldn't be pretty.

At the PPoE, the SMT techs didn't believe they could do 0402s or .4mm BGAs (small ones), either, but once they tried they found they were no trouble at all. 0603 was the "standard", there, though. We've found some (small value) caps difficult to find in the larger sizes. Murata told us that they were obsoleting them and the prices were going way up. I've gotten used to dealing with 0402s so they aren't much of a problem. 0802s are *huge*. ;-) ...though I use a bunch of 1206s and 1210s, too (rarely anything bigger).

0802s are rare, ;-(

I only use one 0805, a 47uF cap. It is cheaper for this cap; otherwise, 0603 or 0402.

0208s aren't, though (arrays). ;-) Of course I meant 0805s.

I use a lot of 10uF and 22uf, up to 35V, X7Rs, so 1210s aren't so unusual. ;-)

They aren't build right on top of an active fault line so the risk isn't great

London is all bricks, after the wooden one burned down in 1666

I know, it was a comment of how you build big cities where the risk of earth quakes or hurricanes are high ;)

around here it is mostly chalk

We build them where the natural ports are. There has to be a city where there is a port, and there has to be a port at the mouth of the Mississippi River.

New York, LA and San Francisco are natural ports too. But NY has never had a natural disaster like the hurricane of 2012. Normally they blow out to sea. It was a very unusual confluence of multiple fronts, low pressure areas, and high tide.

Reply in group, but if emailing remove the last word.

What I wonder is why the Dutch and Danes and so on build their houses so close to the Germans. ;)
