Design news writes – “Some of us remember the “good old days” when we banged out design calculations on a high-end TI or HP scientific calculator. And how we even wrote code to automate the calculations we repeated often! Thinking how cool it would be to do that again on a calculator he built himself, Daniel decided to emulate a subset of the TI-59. His project contains two displays and a serial port, supports the TI Algebraic Operating System and even some programmability. It also includes free source code to get you started. If you are up to it, write more code to add functions and share it with the Gadget Freak community.”

Nice looking project. I just think he made a huge mistake using breadboard for his permanent installation.
It’s great for rapid prototyping but the connections fail fairly fast. The copper wires corrode and stop conducting and they are weak mechanical connections that can come lose when he moves the device.
I feel sorry for the guy when he has to troubleshoot the rats nest in a couple of years (if he’s lucky).
I like the BB look. You could try using clear nail polish to prevent corrosion at the contact point.
