Sunlight in Trafalgar Square

After photoing Dowding, Harris, Johnson and Gladstone, outside St Clement Danes on May 30th (results here), I made my way home, past Trafalgar Square:

Water is easy to photo when there’s strong light around. Rain is hard for an amateur point-and-clicker like me to photo because the clouds that the rain comes from tend to snuff out such light, as part of the deal. But when a machine squirts its water towards a cloudless sky, with strong evening sunlight searchlighting in on everything, I couldn’t go far wrong.

3D printing isn’t the only game in town

Incoming from Rob:

Hi Brian,

I saw this and thought of you:
https://www.xometry.com/

3D printing isn’t the only game in town. This web site seems to make it easier to get access to milling machines. Upload your CAD file and get an instant quote. I’m not sure how expensive it is for one-off jobs but I can imagine it getting cheaper and easier over time.

“This” being a network of enterprises which, between them, can offer: CNC machining, sheet metal fabrication, plastic 3D printing, metal 3D printing, urethane casting, and injection molding.

The point being that additive manufacturing, aka 3D printing, is not the only way to make something. There’s also all these other ways, such as CNC (Computer Numerical Control) machining, that being subtractive manufacturing.

3D printing is not “disruptive”. It is an addition to the repertoire of traditional manufacturers. It offers manufacturers another way to do some of the things they already do, and a few other things they don’t now do.

Anyone can 3D print just about anything, just about anywhere. But just because you can, that doesn’t mean it makes a blind bit of sense for you to actually do this. What if someone else can do it, far better, far cheaper, in some other place, some other way, maybe in a much more trad, tried-and-tested way?

This website puts you in touch with who all those other people might be. As Rob says, It makes manufacturing that little bit easier and quicker to arrange, and over time, ever more so.

Maintenance issues should now be sorted

Any person who have had anything to do with IT (aka everybody) knows, when IT work is being done (even something as humble as doing some rearranging of a little blog like this one), that the word “should” can cover a multitude of unforeseen disruptions. So, maybe the little round of maintenance issues that Michael was dealing with over the weekend and then again this morning (he refers to them in comment 4 here) have, in reality, not yet been entirely sorted. But Michael and I both believe we have good reason to hope that, now, they have been.

One thing that you may have suffered from is that if you clicked on a link from a posting here to another posting here you may, depending on when you did this, have been told “about: blank”, instead of getting to the linked posting. This was caused by the fact that this blog was being migrated (to somewhere cheaper) but migrated before its name had been migrated. It changed its name from “brianmicklethwaitsnewblog” to “3.8.5.22”, and helpfully changed all the links from here to somewhere else here accordingly. It had then to be persuaded that its name was still brianmicklethwaitsnewblog. Which it now has been. As in: should have been.

Other strange things happened this morning, but they too have stopped, and so, touch wood and hope to die, all should now be well. If all from where you sit seems not to be well, please comment to that effect. (That’s assuming the comments system is itself working. Follow the above link and you’ll learn of three lost comments from last night.)

What I’m basically saying is: Sorry if you’ve been mucked about, but with any luck it should have stopped now.

It turned out nice in Stoke Newington

The way I see it, I can do an elaborate photo-expedition, which I did today. Or, I can do an elaborate description of some of the things I saw during my photo-expedition. But don’t ask me to do both on the same day. (See this category.)

So instead of an elaborate description of anything, here are two contrastingly lit and contrastingly backgrounded buildings, which I photoed at the very beginning of my wanderings, in the Stoke Newington area:

On the left, well, I don’t know what they call it, but I like it, because I like any building that is brightly lit, with a dark cloud background behind it, and lots of excellent roof clutter on top of it.

And on the right, the building that is now the Castle Climbing Centre. This time, the background is blue. The dark cloud was the bad weather of the morning and early afternoon, which was departing. The blue sky was the good weather that had just arrived, perfectly in time to illuminate my subsequent wanderings.

Which were fascinating, but exhausting. Sleep well, when the time comes for you to do that. I will, very soon.

3D printed architectural models might soon get good at doing colour

Question asked, by me – 3D printed architectural models are now no good at doing colour:

Note also that if the clever people now developing 3D printing for architectural models were to make it easy to include quite accurate and quite detailed colour variety, then that could make a huge difference when it comes to making high colour architecture for real.

Question answered, by 3D Printing Progress – Mimicking Nature for Fast, Colourful 3D Printing:

Brilliantly colored chameleons, butterflies, opals – and now some 3D-printed materials – reflect color by using nanoscale structures called photonic crystals.

A new study that demonstrates how a modified 3D-printing process provides a versatile approach to producing multiple colors from a single ink is published in the journal Science Advances.

These things always take their time turning from “a new study” into a real thing. But give it about a decade, and architectural models will be looking fabulous.

Now thrive the scaffolders and the craners

Quota photos, yes, but I trust amusing ones:

That’s the Tate Modern extension nearing completion, photoed by me five years and one day ago. So not really now. But the scaffolders and the craners do now still thrive.

Quota photos because I spent the morning failing to finish another piece of writing which just grew and grew. And now, I have to go out and Do Things, which always tires me out these days, so I wanted to have something here before I went out. More later. Maybe.

I hate not being able to go up that Thing and photo London and photo others photoing London. Can wait until it opens. And will. But would prefer not to be having to.

3D printed architectural models are now no good at doing colour

I just googled 3d printed architecture models, and at the time I did this (It may be slightly different for you now), this is what I got, these being the first few images:

I was following my own advice in this earlier posting, trying to encourage Google to tell me about … 3d printed architecture models.

But here’s my point now. Notice how the colours are all monochrome white or monochrome beige or grey, and the like. There is no colour, and in particular no colour variety. I’m guessing that this partly reflects the relative ease with which 3D printing can do shape, compared the difficulty it has doing lots of different colours. And partly, it reflects the fascination with shape and indifference to colour of the dominant Orthodox Modernism vernacular of our time.

Basically, if you want colour, you have to imagine it, just as you have to imagine shape when you look at drawings. Note, however, that drawings, including especially the kind of fake-photos (same link as the one above) of the sort I talked about yesterday, can do colour pretty well.

Furthermore, I would guess that old-school hand-made architectural models might actually be better at doing colour. You just chop and change the materials, and maybe add little colour print-outs to surfaces. Not easy, but easier than 3D printing can do colour, that being a whole step-up technologically.

If you define high colour architecture as the New Thing, and monochrome architecture as Orthodoxy, then the 3D printing of architectural models is a force for architectural conservatism, more so than older methods for describing yet-to-be-built buildings.

You might think that a good thing. Different posting, different argument. I’m talking in this posting about what is happening, not about what I think should happen.

Note also that if the clever people now developing 3D printing for architectural models were to make it easy to include quite accurate and quite detailed colour variety, then that could make a huge difference when it comes to making high colour architecture for real.

An even more portable e-scooter

This, the WalkCar, looks promising:

Promising because it is so very portable.

WalkCar is a small wheeled plate that is fitted with four wheels and an electric motor that takes the ship forward. It weighs only 2.9 kg and is about the size of a small 13-inch laptop PC, giving it the portability to fit in a bag. It is therefore very easily transportable anywhere. Besides, the vehicle height is just 74mm above the ground (about the width of a smartphone); its flat and square standing surface allows you to step off instantly in any direction safely.

This device is not at all cheap. $1,800. Which is much too much. But if this gadget catches on, as it surely might, that price will fall.

As with the regular e-scooter, the WalkCar will take a bit of getting used to, by other WalkCar users and by the rest of us. But, one to watch.

I have already speculated here that the end point of this story will be when shoes double up as transport. When not using these (I am, for now, calling them PowShoos), you can carry them on your feet! WalkCar has the look, to me, of a big stride in that direction.

As of now, this WalkCar is much slower that regular e-scooters, and has much less of a range. But again, those variables will surely improve. The lack of speed may even aid its acceptance by other road users, most especially pedestrians, who are already now tormented by lawless cyclists.

I’ll say it again. This is the big transport story now, not robot cars. Think of it as the motorisation and miniaturisation of Shanks’s Pony.

A rather clumsy attempted solution to the unprotected bike problem

In my various earlier postings about e-scooters, I mentioned the fundamental problem of bikes for getting around on. Because bikes are so big and clumsy to take with you everywhere, bikers must constantly leave their bikes unattended, which means they regularly get damaged and/or stolen.

This afternoon, while out-and-about out in south-east London, I encountered and photoed a very partial answer to the bike protection problem:

I’m guessing that how this works is that you have a special key that lets you into this contraption, to insert or remove your bike.

Setting aside the sheer bother and expense of this thing, the bigger problem is that your bike problem is not typically confined to one spot. The problem follows you. Wherever you go, you may want to get shot of your bike for a while, and bam, sooner or later it gets wrecked or nicked. At least with hired bikes, there is a choice of places to abandon the bike. With this thing, you need to hire a whole new metal tend for each spot you might want to stop at. No. Comments telling me otherwise would be most welcome, but as of now, I just don’t think this works.

If, despite my grumbles, you want to investigate further, I took (see the photo on the right of the above three) a photo-note of the website to go to.

Statues do matter

Or so the recent dramas in Parliament Square would suggest, during which graffiti was attached to the statues of Churchill and Lincoln. Cue angry history lessons from Old People.

So here are a few more statue photos I photoed recently in Parliament Square, including the above two personages, but adding Gandhi and Millicent Fawcett, basically because I like the photos:

And while I’m on the subject of statues, I recently checked out the statues of Lord Dowding (of Battle of Britain fame) and Bomber Harris (of WW2 bombing offensive infamy) outside St Clement Danes, at the other end of the Strand from Trafalgar Square:

I knew that, when I got to this spot, I’d encounter Dowding and Harris. Ben Johnson and Gladstone were both surprises.

Memo to people intending to end up as statues in London: Join the RAF and wear a hat with a flat top sloping slightly backwards. That way, you won’t get pigeon shit on your face. Seriously, someone badly needs to invent an invisible pigeon scarer. Some kind of tiny electronic device that vibrates in a pigeon-scaring way, solar powered so it will go on working for ever.

The above link to my recent pigeon scaring posting being the only link in this posting, apart from the one at the top about the graffiti (so as people reading this in a year’s time will understand which current events I’m referring to), which is a bit lazy and a bit egocentric, but I’m in a hurry to get ready for something else. You surely have all the words you need to find out whatever you want to find out, e.g. if you are a Young Person wanting to find out if Churchill was anything else besides being a racist, or if Lincoln did or said anything about black slavery in America, besides being President at a time when there were still black slaves. (While you’re learning about that, try finding out what Gandhi said about Apartheid, when he was younger and living in South Africa.)
