RPN for life!  I turned it on on the 35s and I have no idea how to turn it off, nor would I want to.

RPN?  bleeeeeech!

spent all that time in junior high learning algebra.

so in 1975 when the professor said we could use calculators or slide rules I bought a TI SR10 and never looked back.

hmmmmmm.  what class was that?  might have been servomechanisms and controls.   geeeeeeeeze.  I am an old bastard.

the rpn guys called me much worse in 1975.  but I have never ever used one of those tools of the devil.

(we unwashed TI users sat on one side of the room so as not to be contaminated by the "reversers".)

More RPN calculators for me!

Indeed!
I have two HP28S and RPNCalc on every PC that I used longer that 5min. Somewhere is a 48-emulator.
I had an ugly TI 58-something as a teenager, which I discarded for a programmable (Casio?). Then I became involved with hex and binary and understood the stack concept. Nothing but RPN shall get near my numbers!

[nixiefreqq]

when taunting the rpn'ers we had to tread lightly.  we could emphasize the "reverse" bit.  why would anyone use a thing that was "reverse"?

but we did not mention the p word.  ya' see there was this large gentleman roaming the halls who was sorta polish.  and a defensive lineman.

was too scared to ever talk to him and sure did not want to ever piss him off.  (remember when mongo came to town in blazing saddles....it was like that)

he went on to play for the jets and was a member off the "new york sack exchange". 

[mnementh]

Just soze y'all know... aside from being Welsh, this dwagon is also largely Polish.

I too was largely offensive line, and I too am offended by RPN. Not by the term, but by it's very existence.

teh RPN pi is a lie!!!

Man, I found another HP Voyager calculator on ebay. HP 15c, with the sleeve and the manual. Do I, or don't I... 

HP calcnuttery?  I don't know anyone with that problem.   

Three cheers for the only type of calculator (RPN) where the operands and functions both operate in the same manner!

[0culus]

Nice collection!

...on a side note, I'm also looking for a print copy of the HP 16C manual. The 16C I have unfortunately only had the sleeve when I got it.

[tggzzz]

Why RPN?

Because people learn incorrect arithmetic from many calculators. If you don't believe me, go and ask a primary school teacher what 1+2*3 is, and see what proportion get the answer right. The clued up ones will ask where the brackets are, to which you should reply "none, just the normal laws of arithmetic".

When they didn't believe the answer, I used to get out two Casio calculators, one of which gave the correct answer, one didn't.

Besides, it is more intellectually satisfying to gather everything you need, and then do something with them. Gathering half, starting to do something, stopping to get the rest of it, then signalling that it can continue is ... messy.

[0culus]

Agreed. I "discovered" RPN thanks to my dad (who bought an HP-45 brand new at college and still has it), and I've never looked back.

[nixiefreqq]

ok.....before I get banned for starting a kerfuffle,  let me try this.

HP calculator trivia: Our beloved pinnacles of numeric precision even made it into one of Clancy's novels, where a 'large HP programmable' in the hands of some missile defence expert is mentioned!

And a little *reverse cowgirl'. May the 'arithmetic' heathens feel that whip!

[beanflying]

Anything Reversed and Polish just isn't right and you get messy hands from trying it seems

My wife is a pervy widdle dwagon fancier.

So I came in from nuking a Prius and...

            

As usual, the finished print looked pretty good, aside from a little X-axis ghosting. Good adhesion; I actually had to pry them loose this time, even though they were fully cooled. I just love popping out the supports... they come off so clean with this printer now I have a proper Tornado profile to use.  Minimal trimming and hot-air touch-up yields excellent-looking product, especially for "Draft" quality 0.2mm LH... even the "bad" side is pretty tight. 

But basic durability testing turned into destructive testing; as I feared, the 1.5mm walls left no infill to add strength to the perpendicular faces of the fins, and they not only broke without trying too hard, they broke easily with just moderate pressure from a thumb.     "Unreasonable care" would definitely have to be taken to keep them from breaking. Those fins in the parallel plane had pretty good durability; twisting with pliers was needed to make them break, and when they did, it took a fair amount of the parent structure with it.   

Given that... I'm not sure even PETG could make this a strong part; the fins are just too thin, as is the area of the core material where it pulled apart. I think I'm going to try two more flipped on end to see if the circular pattern that will produce yields a considerably stronger fin. But first, I may mod it a bit so that last fin is a little thicker and I can get at least a mm or two of high-density infill.

Cheers,

More Radius in the bottoms of the fins would help printed as you did. Printing them vertically would be better then screw would take a fair ammount of the load then across the layers and the fins would be stronger (outside of the Foot to the bed). Not that I have one of those scopes but I might have a play with it and do a PETG one after I finish playing with HP Knobs.

RPN is for people who dont mind that their brain is misused as a stack for intermediate results. My brain has a very low stack depth. But I wrote a compiler that did the tricks with the brackets once and for all ...

Yes, provided we all agree that vi is little better than edlin, whereas emacs is useful

A depth of 4 is sufficient for all "handheld" purposes. If you need more then you need to be using a spreadsheet or full-blown programming language.

I hate it when I come across a calculator and want to calculate the sine of 1 radian, and don't know whether to enter "1 sine =" or "sine(1)=".

Kewl... good that I'm thinking in the right direction. IIRC, these feet have a steel bushing up the middle and it appears this .stl is designed to go around that. It may be that original intent was for it to be epoxied to that bushing for strength.

Go play with your knobs! I'll update if I have time for this diversion after couch-tuber-time widda boy.
