Digital verniers

I would always recommend mitutoyo for callipers and mics but Tesa and Etalon make very good micrometers also in truth you only get what you pay for .

The button battery thing can be weird. I bought a solar welding mask new & a week later it failed. They sent me a new one F.O.C & told me to throw the other away. I delved in & unglued the cover to find two button batteries. Reading on my meter was 2.5 ish volts. Anyway bought two more & they were over 3v resoldered them to main board & bob's your uncle. Now have two working masks.

Digital verniers & digital rules are rare beasts indeed and about as useful as a digital sundial 😁

I bought a set of left hand callipers thinking they would be easier to read but they weren’t and the jaws looked as if they had been ground by drunken blacksmith wielding a bastard file !

I bought a set of left handed calipers from the Midlands Show in 2018 (MACHINE-DRO.CO.UK). Great for measuring parts in situ on the lathe. Only fault is the battery cover fits on the wrong way and easily slides off if held wrongly. Covering with insulation tape solved that.🙂

Is it time to accept that our language has changed over time, and accept that these sophisticated (but in which meaning?) calipers are called "verniers"? We could always go back to an older usage, still used in German, and call the Vernier scale a "nonius".

Perhaps we could then turn on Mitutoyo who use the term "Digital Micrometer" to describe their QuickMike, despite it using a linear scale instead of a micrometer thread? Should however Mitutoyo decide to give me one of these instruments, I would happily use the same argument in their defence

If you wander off to Thingiverse you will find plenty of designs to 3D print you own Digital Sundial.

On thingiverse you can probably also find things like a spring loaded bum wiper along with a laser fly swatter a solar powered torch and many more useless things that mankind doesn’t need .

All of those are just digital clocks that cast a shadow and how does it work in the dark ?
Now a really classy unit could be  made using a gps clock and a laser pointer on a classic sundial face and wouldn’t that make a different clock ! When it is dark a laser dot or line shows the time and when it is daytime it uses a shadow .

Now please tell me you own a rubber surface plate 😂

Someone beat you to it... Digital Laser Sundial.

John

Not what i had in mind

Haven't got round to one of those yet but I have some precision 3D printed V-Blocks

Someone on the net was selling a Time Projector on the net a year or so back. There were some people I'd've liked to project through time, so I thought about it for a while...

Just for fun, here's a real Vernier Caliper:

I've covered up the millimetre scale because that's too easy, but what's this vernier reading in inches?

Dave

29/32 ?

That is one weird vernier  - well it is to me anyways !

125/128" or .977" to the nearest thou from the Vernier scale, but the tape measure value doesn't make much sense against that. Unless it's in Arshins and Vershoks or summat...

Could it be a patternmaker's shrink rule?

Well went to booty this morning & spent £35 on this lot. Well pleased. pic 2& 3 can you decipher for me. Pic 4 anyone got an idea what this is. Have not got a clue what it is but it has a fancy screw & a rack that traverses vertical & horizontal. Thought I might be able to adapt it to do fine work on rings. He charged me £3 for it. Just had to have it.

Simply eighths, sixteenths, thirty seconds and sixty fourths in decimal format. No idea what 4 is, but probably off some sort of scientific instrument.

Andrew

0.742" ???

No 4 almost certainly from a microscope stage. Possibly Vickers looking at the shape.

An essential piece of kit for some! And why waste time 3D printing when you can get one for as little as £5.95 with VAT relief!

Sorry - but I ended up on that page at random yesterday looking for ways to store cables without tangling them.
