HP Releases Hackable ARM-Based Calculator

mikeselectricstuff writes "HP's 20b business consultant calculator isn't the sort of thing that would normally interest the average Slashdotter, but HP has released a Devkit for it, including schematics and source for a sample application, and they appear to be actively encouraging people to re-purpose it. Maybe the engineers thought a business calculator was just too boring for their hardware? The calculator is based on an Atmel ARM chip, and it has a bootloader and JTAG interface to allow user applications to be written and downloaded, turning a boring calculator into anything you can do within the constraints of the hardware."

    But how do I embed the calculator in my arm? Knife and some glue?

    Whoever is in charge of decisions like this at HP really needs to be hired at Apple.

    There is a difference between "programmable" and "hackable," or at least to me...

    "Programmable" implies that a programming language is made available. Nothing more, nothing less. You can do what the programming language allows you to do. Of course, certain limits may inherent (or added to) the language. It is like giving you a sandbox to play in.

    In this case, "hackable" means that they have thrown the doors wide open, and published almost everything that they know about it (schematics, etc), and are inviting people to dream up new uses (which presumably includes hardware hacks). This is like giving you the keys to the house and saying "It's yours. Make yourself at home. Feel free to paint or remodel if you want."

    I happen think that HP makes (or at least made) the best calculators in the world. Then, TI kind of took over after HP rested on their laurels after releasing the 48G series. The 48G firmware, at least to me, was an ugly hack of the 48S code. For example, HP added new units to the 48G. Of course, it would be too easy to add these units to the "units" menu where they belong, so they had to throw them in a "secret" menu that you will only find by reading the manual.

    I love RPN, and love my old 48SX. Even the keypad feels nicer than any other calculator in the world.

    I bet the first thing I'd turn it into would be a brick.
