I ran her through all of it each week before a test and I kept getting surprised she kept saying yes, I had managed to get every most variant of each formula I needed based off Prompt. Before I finally realized she was just letting me teach myself, I had managed to get a 100% for every exam thinking I had cheated it and beat math class.

    I genuinely did this same thing back in highschool in 2014. I integrated a Bluetooth chip into my calculator connected to the 2.5mm IO port which communicated with my phone (which has cellular) to send wolfram alpha API commands from the calculator and receive the results back. I recently thought about bringing it back and integrating chat gpt into the mobile app I made for the Bluetooth communication. It started with me making a line plotter that plugs into the IO port controlled by an arduino that draws graphs from the graphing screen where I reverse engineered the IO protocol of the calculator and wrote a library for arduino to communicate with the calculator. From there I designed and laser cut a little 3 axis plotter controlled by 3 servos. I did that because I was tired of drawing graphs on my math homework, it worked great haha. From there I went big with the wolfram alpha integration. I should have documented it and posted my project online.

    CAS had functionalities like putting in an equation, solving it, and showing the steps it took to solve them.
    Thru a little binary hacking of the firmware files, you were able to load the CAS software on the non-CAS model, couple that with a custom bootloader with the option to reboot out of test mode, we had a lot of fun.

    Many years ago, my schools TI-84 Plus had a firmware lock on them that didnt allow you to load games on them. I quickly realized that I could use the newer firmware on my Ti-84 Plus to do a local calculator to calculator firmware upgrade. So I simply connected my calculator to the school's TI84s and flashed new firmware, firmware that wasnt school specific, so it did not have the program blocks enabled. I was then able to transfer whatever games/programs to the calculators I wanted to, half the class had the new firmware and games installed. I enjoyed local celebrity in that class and people always wanted whatever new games I had downloaded from the internet. This was in 2008. I was the kid that always had the silver edition calculators and used birthday money to afford them, so I could have more games. The kid that did the firmware updates on his calculators at home lol

    😭I made the same thing 3 years ago, but it used Bluetooth (easier to work with/use) to connect to my phone instead. It had a chatroom and Google (no ChatGPT back then) but no photos or games or camera. So, yours is definitely better. Problem was, there was no one to chat with, and yea, Google sucked.
    As for the camera, I think you could take out one of the black screws on the back and hide the camera behind there. On my calculator, the screws were behind rubber feet, so the camera would be hidden. If you have a thicker model with the recessed screws, the darkness should cover the camera. Connect the camera to your microcontroller with a ribbon cable, write a new command, and voila. If you make the command send the image to the ChatGPT API, you should be able to look at your logs to get the image back for future reference. Or just make a camera command.
    As for alternate designs, it just has to *look* like a Ti-84. So, strip the guts, leaving only the shell, screen, and keypad. Glue in lead weights to make it weigh the same.
    Option 1:
    Then you can add in a raspberry pi (remove the ethernet and usb and headphone jack to reduce height if using full size, or just use a zero/pico). Now you run an emulator on the rpi to get back its functionality or use a custom rom. Add capacitive touch to the dpad to use as a mouse (for smooth movement, otherwise just use it to move 100px in the direction of the click. if you pick the second option you can also use 2, 4, 6, 8 for the 4 directions), on for left click, enter for right click. Add whatever else you need (wireless cards, antenna, apps etc.) You now have a mini-pc at your fingertips.
    Option 2:
    Just stick a phone in there with a 3d printed case to hold it in position (otherwise case is too big and phone slides around). Use any sort of microcontroller to simulate the rom-clearing experience/steps. But normally just use the phone. You can have the calc screen click in and slide down exposing the phone screen through a rectangle window, then make the number pad buttons capacitive, so they tap the phone screen. Just write your own app that meets our design constraints (small rectangle window on top, an input button behind every physical button, etc.)
    These are obviously a lot more complex but have their own benefits. Explore if you feel like it.

I realized that this math could be done using matrices and there were awesome built-in software for doing advanced stuff with matrices in the TI-84. I could solve these problems in a couple of minutes with matrices and the built in tool while it could take like 15-20 minutes doing the math manually. Never told anyone so everyone was blown away about how fast I could do the math.

    When I was in high school in the 90s, I had a little enterprise setup. I wrote programs for the TI series calculators that could "show the work" for math tests. I sold these programs for $5 during lunch and study hall. I never could quite figure out a DRM, so there were also resellers. It just so happens that I also worked in the principal's office for one period a day, and they could not figure out why test scores were up like 20% across the board for certain classes. Back then, teachers were NOT savvy about these calculators. It really should've been obvious because these programs weren't *that* sophisticated. They watched test taking like hawks, but never figured it out. The funniest part is, I personally never cheated. Writing the code is how I learned the material.
