Caliputer Review / HowTo
The Caliputer, from the 1960s.
This is episode 36 of my video series about calculating devices.
My own scan of the one-sheet Caliputer manual: archive.org/details/caliputer...
End song inspired by "Hotter Than a Molotov" by The Coup.

Be careful fam: I came here to learn about the Caliputer and somehow almost bought a year supply of Burt's Beewax lip balm on Amazon😁

Jeez. This is a hysterical video considering its about calipers and slide rules lol. Thanks for the tutorial. I found a good deal on ebay, so I have a Caliputer on its way along with a Gerber variable scale and a regular dial caliper. Looks like fun!
Wow, what an odd and ingenious device. I love it...
i never thought i'd enjoy a series about measuring devices so much thank you for the work you do, i love math and it's quirks and this stuff is wonderful.
I used to do the "hold my breath" thing when someone in a TV show was under water, but I had to give it up after an incident where someone paused the movie at an inopportune time.

Stay safe out there!
I had one of these back in the early 1970s. It was neither a good vernier caliper nor a good sliderule. It was the worst sort of mongrel; a faithful companion that would bite at the oddest times.
It's an honour to be one of this week's 10
I know how to draft a vernier scale since the early sixties. It remains a handy thing to know. It's not German, but my teacher was French.
God bless this channel
I was at a tea and coffee morning a few weeks ago, and someone bought in a beautifully made sextant the protector part of the device has a vernier scale with a high magnification lens building for reading it a bit hopeful for getting that sort of accuracy while on a moving ship I would’ve thought.
It's weird that they couldn't make the combined nibs a nicer number, like 0.2in
I'm sold. I NEED ONE!
I'm so glad I found this channel, I love weird analog calculators, I want to be a machinist, and I love dry humor so this video ticked all the boxes for me.
9:20 they made a game about that. It’s called asphyx and you have to hold your breath when the character does
Whenever someone on screen is experiencing something that should be putrid or stinky, I instinctively don't breathe through my nose in case I can smell it too.
The vernier gives you resolution, not accuracy. Most machinists I know won't trust even a mitutoyo caliper to less than a couple thou.
Burts no longer with us, but there's an interesting documentary about him

I have one of these, but it came without the instructions that I see in your video. Are these anywhere online? I've failed to find them. I would love to see a scan or pdf. Thanks so much for putting up these videos - terrific style of presentation!

I dont have a lot of vernier devices lying around so its not something I can test. But I have always wondered something. You know how without a vernier, we can "guestimate" an extra digit of precision by seeing how aligned we are/are not, to the nearest two marks? I was wondering if there was a way to do this with a vernier. If the vernier gave me one more digit of precision, can I still guestimate one more on top of that? If so, how? I imagine the process would be different.

If you look at the entire vernier section for the place where the lines match up the closest, that is the indicated digit. This may be extended to get another 0 or 5 at the end with a sort of binary measurement - if the lines align "exactly" the extra digit is 0, and if two neighboring lines on the finer scale are "inside" the two nearest lines on the coarser scale the extra digit is 5.
I'm not sure I've ever seen calipers (or anything else for that matter) with an adjustable vernier - maybe it makes manufacturing easier, since they need to attach the risers to put the vernier on?

I haven't either- the manual says you can adjust it for calibration. But I'm not sure why you'd need to calibrate them- the only reason for them to slip out of alignment is because of the calibration screws! I don't know why they didn't just print them on the middle scale. I think you're right- maybe just to rise them up a bit?

Chris Staecker if the verniers were on the lower, middle scale then you'd get parallax error if you read it from any angle other than straight on (plus, it's harder to line up two things if there's a cliff in the way)
I hold my breath in those scenes too.
feeling quite inadequate here with my browne and sharpe dial calipers
3:03 Circumpherence?
6:10 in English, Vernier is properly pronounced "very-near."
Just got mine in the mail, I'm surprised at the framerate and the fact that it can run Minecraft
i want one in metric!
You are so effing funny.
Oh OK I found your vernier!
Circumference, with a PH 😁

@@ChrisStaecker They would rush to sponsor your channel if they look at what your video did to the page views for the "Vernier acuity" article at wiki. The Pageviews Analysis shows the page was getting ~30 views. Then Chris published his video, and it jumped to more than 300. And the number of page views remains above the pre-video level. If only one of Chris' videos can inspire a 10-fold increase in the number of views of -- and ongoing interest in -- an obscure webpage, then what might sponsorship of a number of Chris' videos do for the sales of the quality products available from Burt's Bees?
Compaliper isn't much better than Caliputer.

Its a computer made in.....Cali
So a caliper for mathematicians. Seems awkward to use, probably for putting into the pocket so there is no sharp edges that will cut and tear your clothes.
Looks a mildly good idea, done in the crappiest way possible..🤔🤨😏
Sorry, but I just have to correct you... It's VER-ni-er, not ver-NEER. It's not commonly called a verNEER in English, just by Americans who've never learnt how to say it.

I've only ever heard "verNEER" in english. But these all sound stupid to me. English speakers for the most part try to say "Fourier" approximately like the french would. Why not for Vernier? No sense labeling one bogus english pronunciation better than another bogus english pronunciation.
