I actually have two of these, one that is "stock" and one where I added access to the internal jtag port so that I could run my own code on it.
As a note to the HN crowd: we’re facing an intersecting UX challenge. The vast majority of our users aren’t very technical - they’re high schoolers really. But we also want to cater to a more advanced audience such as engineers.
Initially we thought it would be really hard to please everyone. But it turns out it’s actually possible to create a simple interface that still lets you do more advanced functions. And even better, designing for the “newcomers first” turned out to be a great guidance when designing our software. Judging from the feedback we get, assuming the user won’t ever read any manual or doc is actually quite a good starting point!
Also, have you seen the DM42? It's not a graphing calculator, but since similarities exist with numworks.
In the category of "all different", my all time favorite calculator is the TI-92+ which was a landscape style calculator with a qwerty keyboard. Building something like that with the 5" 800 x 480 IPS screen that STM has on the STM32F469i-Disco board would be heaven. It is on my long list of things which I will likely not get around to before I die :-). You could swap the STM32F769 for the 'F469 if you wanted more mips. I'd pay $300 for one of those, if you're wondering.
Well, technically we did send one calculator to Australia. It was a gift to Damien, MicroPython’s initial author!
My use case is high school students, if you have any thoughts on that.
We actually designed it with high school students in mind. We interviewed a lot of them, and we reached the conclusion that on average they were using less than 10% of the features of their calculator.
So we designed ours trying to make it as intuitive as possible. You'll notice it borrows from gaming consoles and mobile phones: that's because high schoolers already know how to use those!
As an example that might seem like a minor detail, we're the only graphing calculator on the market with anti-aliasing. It might not sound like much, but it's a lot of work to get right and that's the kind of detail we like to pay attention to.
Anyway, you can judge by yourself: our (free) simulator is just a click away: https://www.numworks.com/simulator
