New tool day. I count it as #SlideRule related.
This is an #Aristo 1100 Planimeter, a tool to measure areas from drawings or maps.
The QA sheet inside dates it to about April 1962.

Do I have any clue how it's supposed to work? Nope.
Do I have a manual? Also, nope.
What could possibly go wrong? πŸ€ͺ
Oh. Not to forget: most ends have sharp needles and pointy ends. Totally safe for somebody like me.

Did a cool maths workshop with @Ayliean earlier at #emfcamp and spotted this #Aristo beauty on the wall. Immediately thought of @VintageProject :) #Sliderule

I had to use the #SlideRule early in my #engineering education, many decades ago. Since then, I've collected many slide rules from round the globe. Of those, my absolute favourite is the #Hemmi 130W Advanced Darmstadtβ€”one of the most basic models.

I admit that this is rather a brazen statement in the face of #FaberCastell 2/83 N Novo Duplex, #Aristo 0969 StudioLog, #Nestler 0292 Multimath-Duplex, #K&E 4081-3 Log Log Duplex Decitrig, and many other duplex, advanced, engineering slide rules.

How Slide Rules Work Β· Amen Zwa, Esq.

I really like how these seem to be coming up more regularly.
#Aristo Studio 868.
Really handy for your EDC. πŸ˜‰

#SlideRule

Just for fun: This is the #SlideRule that started it all. My dad's #Aristo #Studio.
He used it during his communications engineering studies in the early 1960s.
(I think he started around 1960, before my parents were getting married in 1961. The toaster we still use was one of their wedding presents.😊)

He gave me this one some time before I took up my own studies, but I didn't learn how to use it until well after my university time. He tried to teach me but gave up, eventually.

Had a game of #aristeia with a friend at my local store. Love trying out newly painted miniatures for the first time.

A nice thing about Aristeia is that minis come back when they die. Important since new paintjobs die first.

Re FUBAR:
Here is a detail of the trial one. At some point the frame bracket broke and it seems it was glued.
It holds up fine but looks terrible.
The damage wasn't visible in the offer but the spares make up for the 10 EUR I paid.
So this #Aristo #Studio donated its case, cursor, and accessories to other slide rules. Fair enough.
After new glues arrived today, I tried and glued the two broken #Aristo #Studio slide rules.
One is pretty much fubar, so that was the trial run. Had a bit too much glue and thus some cleanup to do, but it worked just fine. Second one is supposed to be used, so I was a bit more careful apied what I learned.
Pretty nice #SlideRule again. Not a shelf queen but very well usable.
Awesome!

What grind my gears...
When sellers hide damage, no matter if intentionally or because they don't care.
See this #Aristo #Studio 0968 here? It's rough and has quite a bit of use, but also has a broken frame.
Yes, it can be patched, but why not tell beforehand?
I paid 12 EUR and the cursor alone makes up for that, but I'm still disappointed by people.

I have a frame and slide from one of the recent repairs, I think. πŸ€”

Checked and yes, I have a better frame. Also needs gluing but that's quite inconspicuous as it's just a glue bond that broke, rather than the whole bracket.
