Hypothetical WP 35S

[damaltor]

I actually have a different idea. As i am an electronics developer, i would rather make a new calculator. This would allow us to customize each and everything. The electronics part is one big piece of work, which i could mostly solve after a big brainstorming. Making professional PCBs in china for cheap is easy, and affordable (i stopped self-etching my home projects, i usually order them in china - depending on the size, the cost 10-225 US per 10 pcs (!!). They usually arrive in less than 3 weeks here in germany. The same is what i did for my CASIO USB-Interface for the Casio Basic Calculators or the 2.25 MB Ram-Upgrade for my HP48G).

I actually would keep much of the 20b design, but allow e.G. an expansion port, for adding modules or reading in data and such.

But the housing is a different part, in which i do not have much knwoledge. We might just design a housing and upload it to shapeways...

Alternatively, how about transplanting a new (oled? nice readability, easy graphics, needs some current, or lcd - less current, but not as beautiful) display into a 30b or 20b? this would allow keeping much of the wp34s codebase. I would help rewriting the display driver. Still, 20b are not very nice, and 30b start to get infrequent or expensive.

I know, the DIY calcs are somewhat heavy work - but why shouldnt we tackle it?

maybe, if the project goes well, we might even kickstarter the project...
