Home made calculator


In this forum, it was discussed several times the feasability of a home made calculator. The conclusion was that electronics are the easy part, and the case the difficult part.
¿Could it change in the near future?
Take a look at
www.fabathome.org, or www.reprap.org

If this technology arrives to a happy end, everyone could have a totally personalized calculator, according to their own desires (or necesities).



You can already do this yourself with the eMachineShop software http://www.emachineshop.com/
Just choose the "rapid prototype" option, push a button, and your prototype case comes to you in the mail.

Home made calculators have been built since 1972, when the first kits became available.
If you are really into it, I'd suggest to grab some old TMS0105-based calculators with Klixon keyboard and desolder them, pick up an existing PCB layout and modify it to your needs. As the keyboard is the hardest part, the robust Klixon keyboard eleminates one of the most difficult parts in the construction.
Case tooling is available online, or you might want to try on of those "instant molding" kits...
