Since everyone seems to be all about space programs, here's a very silly joke device from 50 years back: The Zlotnian Calculator, "Official Digital Calculator of the Zlotnian Space Program"

While it was a joke, it was made by a very serious surveying instrument company, the Slope Indicator Company of Seattle, WA.

getting there ...
@scruss count to 20 if you take your shoes and socks off and 21 if it's warm enough
@ukscone I'm syndactyl, so my toes only go up to 8. Octal 4 Lyfe!
@scruss @Nickiquote The instructions show an epic commitment to the bit
@davidbcohen @Nickiquote yup, they didn't hold back

@scruss @davidbcohen @Nickiquote

Allowing for political changes over the years, the current location of Zlotnia is Uzhhorod in Ukraine (where there is a big gas pipe supplying much of Europe).

I wonder if someone from Slope Indicator was originally from there?

@vfrmedia @davidbcohen @Nickiquote according to Nicola Marras in the Proceedings of the 22th International Meeting for Collectors of Historical Calculating Instruments, it was designed by Audris Skuja, originally from Latvia.

@scruss @davidbcohen @Nickiquote

that makes sense - whoever did it had the geography of Eastern Europe in the map spot on, but it would have also made sense to pick an area many km from where your family still lived, in case the Soviet authorities lacked a sense of humour..

@scruss

I could have used several of these in the classroom, for students who forgot their calculator on exam day.

@scruss
As yet, no 3D print file...
@vik when have I ever disappointed ...? Gimme a minute, just got to find the right font

@vik okay, now it's done:

The Zlotnian Calculator (reproduction) — https://www.printables.com/model/1672286-the-zlotnian-calculator-reproduction

I wouldn't normally print detailed stuff in PETG, but it was in the printer, so it's what I got.

I even fitted the optional memory function!

By 'eck, OpenSCAD's nightly's Manifold mode is quick. This was about 90 seconds to render, while regular OpenSCAD is 40 minutes (and 3.4 GB RAM) in with no end in sight

@scruss
A few days late for the 1st but still cool!
@vik the horrors are never ending, yet I remain silly
@scruss
silly? looks evry bit a castcard set of brass knuckles, jawbreak guaranteed

@Beatpoet13 it's definitely plastic: look at the pictures on the site.

Use this in a fight, you get all you deserve

@scruss ok cheers another obsolete production line ...

@scruss Love this.

But, maybe I’m missing something, why are holes #3 and #2 that way round? They seem reversed to me?

@alexanderdyas no idea. Maybe that was part of the joke in 1976?
@scruss Looks like terrible brass knuckles.
@JustinDerrick maybe better as an ice scraper
