Ben Heck's DIY Graphing Calculator
« on: July 03, 2015, 09:32:00 pm »
Seeing all the attempts at people making their own calculator, I found this quite relevant. Still watching at the moment, but seems like a pretty neat project. Also, I love their intro. :P

I don't have the time to watch the vid right now (trying to program :P ) but it looks great :)
Creating my own calculator and potentially mass producing and selling it is always something i wanted to do  :D

Yeah, I love the "regrettable acting" in The Ben Heck Show. I was disappointed though at how lousy the "calculator" application was. It was a super simple command line program that didn't even do any expression parsing, a python prompt would have been better!

Do you want me to show you my parser program? :P Ive only done token parsing and its already a mess, 'couse siriusly, parsing aint easy.  ;) So i wouldn't expect expression parsing :P But then again i haven't watched the video yet so we might be on to different pages.
Edit:
From my conversation with Ivoah over IRC it seems that a math parser is not as hard to make as a C parser,which i had in mind. Where, however, can i find the documentation for the stuff done in the video? I have searched the element14 website, but cant seem to find anything.
Edit 2:
"its ironic that if someone does make there own graphing calculator, it will most most likely use parts manufactured by Texas Instruments :("-c4ooo over irc

Yea, unfortunatley, the calculator didn't do much. Given the time constraints and all they had to do I'd say they didn't do to badly though.

Are qwerty keyboards really that important? (Given that you can easily attach a keyboard via usb)
I was just thinking, should a diy calc future a qwerty key layout? I mean, if you keep the vertical design, like most calculators do, there is no way you can fit a qwerty keyboard on there. And if you flip the calc on its side, like the voyager, then becomes very awkward and un-calculatorish, (https://education.ti.com/en/us/~/media/Education/images/rightcolumn/products/graphing/Voyage200_L.jpg?mw=280).
So, is a qwerty keyboard really worth that awkward, vertical design? (Most people want qwerty, seemingly at no matter what cost) Remember that for a diy calc, a usb for a keyboard is more then likely.

I think the success of the TI-83 Series shows that QWERTY isn't necessary. I think they just wanted to multipurpose their device, but it made it a bit awkward imho.
