.

I'm afraid it probably depends what you're uploading them from.

If you're using an iOS device, I may be able to help.

… Other devices probably work in different mysterious ways.

It works beautifully on the iPad, so should be good on iPhone too.

Rotation, cropping, re-sizing, etc. etc.

I had this problem a while back,

If you are using windows the solution is quite straight forward, when you get your photos from your device, don't use the windows auto/ cropping "image viewer" software,

the computer generates information that changes the photo for you, but not for anyone else, hence when you upload it to the internet, it's still sideways.

So open the file with paint, change anything you like to it, rotate/crop it if it needs it, sometimes it doesn't, and just either save, or save as jpeg and when you upload the paint edited/saved version, it will show it the right way up.

PS; just noticed you're using apple, so ignore that, but could be used as a method by anyone on the windows boat.

Well working away quite merrily today and got a text at 4:30 from the Delectable Debs

"Your dinner is done "

So jumped into the Donald drove 110 miles up the M6, M56 and M53 and went and got me dinner as ordered, had a nice cuddle and drove back, another 110 miles but at least this was downhill.

She does a nice dinner but an even better cuddle.

Actually the dinner and cuddle was nice but real reason was to swap the Donald over for the car as it's wanted in the garage for MOT tomorrow and a bit of specialist work.

So tomorrow night it will be a repeat performance so she has the car at her end.

Bought 2 Michelin tyres online from Kwikfit , promo offer -bargain price , had them fitted today at local kwikfit .. they're dated 49 14 …older than my worn out ones !

I had to buy two for my car, I took it in for a balance and fair cop both bald on the inner edge Keeping your tracking OK is pretty much impossible with Staffordshire road maintenance standards, I think they have rebranded the Highways department Holes 'R' Us.

Still I got a decent life out of them for budgets and the two back ones bought at the same time still have 6mm of tread on.

Then an hour and half to do the ten minute drive home because of this – jack-knifed lorry on the A38:

Just come in from a cold garage to take a couple of photos for the Worden build album. Happy with the progress so far. It's taking me a long time to do, but I'm getting there! Only time will tell if my mods to the original design will turn out to be improvements, or not.

On the left is the (appropriately) left hand side of the business end. I've changed the traverse mechanism in terms of materials as well as the means of actuation, which now includes a locking device. Right hand photo is the other side, showing the revised arrangement for traversing the table. The screw has been changed for one with a 1mm pitch and the whole is moved with a graduated handwheel from Arc Euro Trade. On to the motor mount and wiring, next, I think.

I've been drawing the parts for an Austrian Railways Duplex loco in 3 1/2" gauge. With frames over 20" and the front buffer beam 6 1/2" long I think I'm about to launch a behemoth. How the prototype ran being such a size God only knows.

[Chris Evans 6Participant @chrisevans6]

Neil, I guessed it was something on the A38. I live on the A513 and it took three quarters of an hour to get from Alrewas to Kings Bromley, about three miles.

[Michael GilliganParticipant @michaelgilligan61133]

I have just spent a happy half-hour at the microscope, examining a slide of the spinnerettes of a Cross Spider [Araneus diadematus] … I can't hope to do justice to this construction with a conventional photograph, so here are a couple of links to generic SEM images.

With a 40x objective and 6x eyepieces, I can clearly distinguish the construction of the individual spigots, but not the surface texture … The SEM images reveal the true beauty.

Our 3D printing nozzles look awfully crude by comparison.

Amazing – many of the wonders found in the animal kingdom. If you could contain the chemicals used in spider silk and set them up on a 3D printer, you'd possibly have a new materials and fabrication industry without the need for metals or plastics.

[davebParticipant @daveb17630]

Amazing stuff, spider web, if you walk face first through a web, it stops you in your tracks, just goes to show how strong it is! In the early 60s we used to use it for cross hairs on old telescopes, it was delivered wound on small cardboard frames. The foreman told me it was produced on a spider farm and the spiders would only produce for a short time before they went insane due to spinning for hours and not getting anywhere. I asked what happened when they went mad, he said you stamped on it and got another spider. He may have been pulling my leg.

I have just bought an iPad and have spent the afternoon trying to work out how to use it. I can now take photographs with it and use the internet. I have failed to work out how I can download photographs from a camera or PC to it without sending myself an email.

It has a thing called a Lightning Connector. The cable with the mating connector has a USB2 connector on the other end. This mates with the charging equipment and I guess will connect successfully to a PC. I have not tried that yet but I hope it works.

[Clive HartlandParticipant @clivehartland94829]

Re the spiders web for telescope reticles, they starve the spider and if they do not the resultant spiders web will have small dots of faece's on them. The reason to use spiders web is that resists the recoil shock of the gun firing.

So today after a bit of negotiation I bought an Airedale bitch 12 weeks old, I will name her 'Tess', This will be my 5th Airedale since I was 7 years old during the war years. Most of the negotiation was about my age and would I be able to keep up with her! I have so far today. Tomorrow I have to go to the Vet with her to get her vaccinations done.

JA, I'm working on that just now. The Apple connector is waterproof (Why?) and very expensive. I am getting a videocamera to interface with a PC, laptop, domestic tv, my smartphone and the internet. So far so good. I am so glad that standardised connections have been agreed., or adapters available to connect one to t'other.

My Android smartphone has a camera icon. When selected, a switch allows stills or video, then a single press on the shutter icon sets it off.

It's been a four C weekend.

CAD:

CAM:

CNC:

And the final bevel gears:

The fourth C? That's from the well known modelling equation:

CAD + CAM + CNC = Cheating!

Actually there's a fifth C, I've got a cold. At least I can let the CNC mill get on with it while I sit in the armchair, in the warm. Another plus is that I didn't break the 1mm ballnose cutter.

O.K. Neil

First, a correction: The objective on that 'scope is 45x not 40x

Second, some excuses:

1. The slide is a squash mount, so the structure is rather flattened
2. I'm not much of a sketch-artist
3. My first Cataract operation is Wednesday morning !!

Now … The Stereo microscope simply doesn't have the resolution to see much detail, but shows five spinnerettes in the spinner. The Leitz binocular does a pretty good job:

With the 10x objective: It appears that the spinnerettes are roughly globular [the wrinkled surface is probably because they have 'deflated'] and I suspect that they might move like the air vents on a Mk.1 Cortina. They are sparsely covered with hairs, and I think the 'spindles' are modified hairs.

With the 45x objective: Some detail of the spindles can be seen … but we're limited on resolution, and it is only having seen the SEM images that I can tell that their apparently long hairs must actually be a short bristles which have some silk 'extending' them.

So … One strand of Spider Silk is five sub-strands, each of [guess] sixty sub-sub-strands, all fused together at the point of departure from the spinner. … All this from a 'printhead' about 1.8mm across.

.

If anyone knows more … please add.

Busy weekend for me too. Yesterday connecting up the water and waste connections for the new utility room, toilet and workshop sink and installing the cupboard and worktop in the utility room. As you might expect, I will need to find an unusually tight soil pipe bend due to the positioning of the socket outside (seems to be traditional), so that job is on hold. Today preparing to power up the first radiator in the workshop and fitting the roller shutter door.

I thought it best to paint the walls before fitting the rad and door, then fitted the hanger brackets before I realised I'd run out of 10mm pipe fittings. Job on hold until tomorrow evening. Still, plenty other stuff to get on with. But the sooner I get some heat in the workshop, the sooner it will dry out and become habitable.

Then onto the roller door. Quite simple in the face of it – bolt the runners either side of the opening onto the wall and the side plates above that, then lift the roller into place. Then "simply" drop the shutter ("curtain&quot over the roller into the guides. Hmm, rather heavy for me to manage that, most of the sprogs are away at uni and my wife is hacking the hedge back. It's damn near impossible to grab a hold of the leading edge of the thing from underneath and the further you lift it the heavier it gets. I'd wrapped some bubble wrap around the roller to protect the curtain from damage but that turned out to be somewhat premature.

I'll resume later in the week once I have a cunning plan, probably involving some webbing to draw it over the roller in a vaguely controlled fashion and / or drape the curtain over a pair of tall step ladders.

It will take "some time" to finish this project off so I will obviously get the workshop functioning before the myriad tasks involved are all complete.

Clive, it's bad enough getting a faceful of spider web without knowing its covered in spider poop.

It is far easier with two people, there was no way I was going to get mine in place on my own but then again it is 3 metres wide.

I had problems trying to think of a present for a friend whom I haven't seen since prior to Christmas, Its tricky when you don't know what to get people. So I cut a piece of 1/8 brass out and made him a nameplate, so that way he can stick it on something he does like! I got a bottle of port as well, not only because it's my favourite tipple, but it's a very seasonal drink. I cut it on the mill with a 60 degree carbide tool, ground half way back on it's face. It cuts lettering very well. I shaded it with a permanent marker to help the lettering stand out and polished it with a cloth after some wet/dry paper was rubbed over it.

I'm sure he will never see this but he has been a good friend to me and helped me much through a difficult time. Thanks again,

MW

Mended a washing machine.

Alas I have become the go to guy for all manner of domestic repairs since friends and relatives found out that I cut metal for fun. So much so I'm thinking of doing a MEW article on unblocking toilets so the rest of you can acquire one of my more popular Model Engineering skills.
