Inspiration
We wanted to make a calculator that could run full fledged data processing software such as Octave.
What it does
It allows for data collection, lab instrument control, calcuations, sensor data collection and anything else a linux computer should do.
How we built it
We salvaged a broken TI-84 calculator and mapped the keyboard matrix with an arduino. We hacked the case to fit all of the electronics and installed a Raspberry Pi 3 inside.
Challenges we ran into
The ethernet refused to work on our expansion connector, and also various other soldering and software challenges such as drivers not cooperating well.
Accomplishments that we're proud of
Mapping the keyboard to the arduino. Fitting all of this hardware into cuch a small form factor.
What we learned
We learned how difficult it is to reverse engineer products to link them together in such unconventional ways.
What's next for NI 84
I would hope to get it fully functioning as it was to difficult to integrate the hardware with only a two man team.
