Casio makes some good calculators. Which one do you have. I use this one every day.

Hello,
How to move forward than casio calculator?
I don't think I understand the question. If you're asking what's a good engineering calculator I can tell you that I'm a big fan of HP. I still have my old HP25 from the mid 70's. They employ RPN, which I prefer. I have nothing against Casio either. I used $25.00 Casio wrist watches down to 185 feet. They never leaked!

What's your calculator going to do that's not currently available? Chris #### BobK Jan 5, 2010 7,682 I think that is what he is asking. Given what is out there for basically no money, this not a viable project. Bob #### ElectronicsR Mar 23, 2016 72 What's your calculator going to do that's not currently available? I want to sell calculator made by me and earn money. #### davenn Moderator Sep 5, 2009 14,016 I want to sell calculator made by me and earn money. I don't think you realise what is involved to accomplish this do you have an electronics factory that is capable of designing and building the electronics ? do you have a plastics factory that is capable of designing and building the cases ? do you have a programmer(s) that is/are capable of designing the needed software ? do you think you can build it for US$10 or less ?

do you have lots of money backing to finance your plan ?

what do you think your calculator can offer that the dozens of types, already out there, cannot ?

You need to be able to answer all those questions
If your answer is no to one or more of those questions, then you are going to find it very difficult to achieve

It isn't going to go anywhere useful

ElectronicsR .... you need to go study and learn lots more about electronics and manufacturing. Not something you can learn on a forum
