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.

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!

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.
