Apparently, I can repeat most of my #SlideRule shenanigans over here. 😁
Here are my favourite ones. #StudioLog and #HyperboLog by #Aristo.
Both were top of the line slide rules for scientific work. (as far as I know)
The HyperboLog is quite hard to come by while the StudioLog surfaces in waves every now and then.

Just look what we have here.
Won an auction that I somewhat forgot about and today it arrived:
A pretty complete #Aristo #HyperboLog #SlideRule. Just needs a clean and a place on my desk. Comes with the hard case and a set of stands.
(This one is pretty hard to come by. I'm lucky to have snagged a total of two by now. Still looking for a HyperLog.)

They just make them like this anymore. Or at all.
