Smallest scientific calculator available?

Discussion in 'Hobby Electronics' started by David L. Jones, Dec 29, 2006.

  1. Ok, I'm getting a bit miffed at not having my scientific calc on me
    when I need it, so anyone know what the smallest *scientific*
    calculator currently available is? Something I can *really* throw in
    the pocket or lab coat etc.

    I used to have a Casio CFX-400 watch which was the ultimate (and as far
    as I am aware, the only scientific calc watch ever made?), but it died
    many years ago and they are now ridiculously collectable, and hence
    expensive.

    Something credit card sized would be nice, like those credit card solar
    4 function jobs, but I want something with at least half decent
    scientific functions.

    No doubt a few will praise the HP 10C series, but at 130x80x15mm and
    113g they aren't really "pocket size" IMHO, and of course are stupidly
    expensive. The Casio FX-82 solar in comparison is only 125x66x8mm and
    47g, pretty good, but I'm looking for something smaller if possible.

    This one is pretty nifty at 90x59x10mm:
    http://www.takshun.com.hk/productdesc.asp?code=726
    But I have no idea where to get it from.

    Any more ideas or pointers?

    Thanks
    Dave :)

    At 317x41mm it's not even in the running, sorry Don.

    But battery life is a plus.
    You can also get a self-oiler for them.

    The FX-82 solar doesn't have a battery life problem.

    I've done away with just calculators since I got my first PDA years ago.
    They all have excellent scientific calculators available for free
    download, and, of course, they can do many, many other things, too.

    My present system is a Palm Zire 31 with the SC-103PU scientific
    calculator and the VisualCalc and MemoCalc programmable calculators. It
    really does fit into any of my shirt pockets, unlike some of the fancier
    ones I had before.

    And, yes, I still have my K&E slide rule from the early 60's. My dad
    gave it to me when I went away to college -- he got a huge discount
    because the shipyard he worked at bought them by the cratefull for their
    engineers.

    I have one of those - not working. I also have a Sinclair Scientific AND a
    Sinclair Programmable.

    Yeah, I've got a PDA too, and yes it can do many many other things. But
    I want just a calculator, not something that does a zillion other
    things to chew the battery life in a week. And call me old fashioned,
    but I like a calculator with real buttons you can press.

    I paid (I think) $20 for my CFX-400 back in the 80's. The part of the
    case that supported the band broke off after about 10 years, so it was
    no good as a watch, but it was still functional. I sold it for
    something like $300 many years back to some guy in the US, even before
    the days of crazy eBay prices. He had a good case and wanted the
    working electronics.

    Even not working, yours might be worth something...

    I picked up few 'made in china' tiny sci-calcs like that for $4.00 at
    Big Lot.

    They carry all kinds of close-out stuff there. Do you have one in your
    area?
    http://www.biglots.com/

    Another good close-out store in the norteast US is 'Ocean State Job
    Lot' they have them too.

    My Picket N600-ES Log Log Speed Rule served me well thru college. It's
    only 153x30 mm, 34 g without the carry case. Works well in moderate
    light.

    I used to have a CFX-200. I just saw a working one on Ebay for
    USD1000. :-(

    http://www.veiks.com/misc/cfx200.html

    I wonder if the user manual will fetch anything?

    My "area" is about the size of North America and located somewhat below
    the equator!
    We have a few similar stores though, will keep an eye out from now on.

    My Palm-PDA-Phone Explore G11 with easy-calk on it. It is much smaller than
    a phone and an Palm-organizer together with a pocket calculator :)

    > things to chew the battery life in a week.


    I charge my phone regulary so I always have power available instead of
    battery driven calculators that dyes even when I need it really :)

    > And call me old fashioned,
    > but I like a calculator with real buttons you can press.


    I can't see your fingers, I can touch the fields with mine :) But most
    times i have a penscil in my hands when I need my calculator their bach is
    quite useable to write all signs that I need.
