RE: AriCalculator is a home made pocket calculator.
Alejandro,

Do you have pictures of your homebrew calculator collection online?

I have a certain bias towards MC9S12 microcontrollers. They're MC9HC11 decedents. They have decent memory sizes. They're automotive products, so they will be around for a while. And I know the members of the design team and trust their work Smile. So I've been using S12 devices for almost all of my hobby projects.

The firmware of the AriCalculator is just the beginning of the development, so at this point I would be happy to have HP-41-like functionality implemented. Eventually the RAM will be the limit of what you can do with the device.

I'm curious to see how your keypad designs look like. I choose small buttons, because they are widely available and because they allow me to put all the label on the enclosure. Bigger buttons are more comfortable to use, but the labeling is difficult. Maybe multi-color 3D-printed button caps may be a solution.
