Above and to the right of most keys is a letter written in green. The curve looks great, we were talking on IRC about the possibility of custom resin 3D printed caps that could have varying heights to simulate a curved profile PCB instead? You must press [ALPHA] before entering each letter. I would definitely look into getting this if it's built. The second key on the bottom row is for adding control for some key backlighting, or maybe some other feature, as backlighting on opaque keys in kinda pointless. The keys on the TI-84 Plus are color-coded to help you easily locate the key you need. The light colored keys are the number keys. I now there are lots of etsy-ers that can print this kind of stuff. I'm not super good at electronics, but I'd love to help with what I can. I'm a serious mech snob, so I would love this. Hunting for the function in blue can be tedious. The TI-84 Plus is an enhanced version of the TI-83 Plus.The key-by-key correspondence is relatively the same, but the 84 features some improved hardware. control the movement of the cursor. Remove the internal battery for a minute or two. 2. [ENTER]: This key is used to execute commands and to evaluate expressions. I am assuming the "Using the Keypad" section coincidentally shows the physical row/column location of each key when it shows the bit/address location. The [ENTER] key is used to evaluate expressions and to execute commands. But if I blink fast enough, I see it in Grayscale.". Have your own thoughts to add to this or any other topic? He cofounded the TI-Nspire SuperUser group, and received the Presidential Award for Excellence in Science & Mathematics Teaching. 3. For example, because the letter O is in green above the  key, to enter this letter, press [ALPHA] and then press . Resin printing might not be a bad idea, but butting legends on resin prints may be difficult. unknown, I'd start with some basic trouble shooting. Then all you have to do is press the keys for the various letters. If you want to erase the contents of the Home screen, repeatedly press this key until the Home screen is blank. However, if you want to enter many letters, first press [2nd][ALPHA] to lock the calculator in Alpha mode. Current Design Render: Flat with angled feet, cheap to produce, can fit in your backpack: Very cool idea - it reminds me of the KeyI-84: "My world is Black & White. TI-84 Plus Calculator Keys to Access Functions By Jeff McCalla, C. C. Edwards Starting with the fifth row of the TI-84 Plus calculator, you find the functions commonly used on a scientific calculator. The remaining rows contain, among other things, the keys you typically find on a scientific calculator. The keys on the TI-84 Plus are color-coded to help you easily locate the key you need. For example, π is in blue above the [^] key, so to use π in an expression, press [2nd] and then press [^]. As expected, the right arrow moves the cursor to the right, the left arrow moves it to the left, and so on. The arrow keys. In Function mode, this key produces the variable X. In Parametric mode, it produces the variable T; and in Polar and Sequence modes, it produces the following variables: The arrow keys control the movement of the cursor. If you have an idea for what function this could be, ideas are very welcome. I was going to suggest that a lot of programs (and particularly games) user arrows + 2nd/alpha for controls which would be difficult with Option 1 - So I think Option 2 is a good fit. [CLEAR]: This is the “erase” key. [CLEAR]: This is the “erase” key. The following keystroke and keys are invaluable: 1. Chapter 1: Operating the TI-84 Plus Silver Edition 2. Edwards is an educator who has presented numerous workshops on using TI calculators. FV ⇒ This key refers to the Future Value. This may be a double-post, but I think this is a bit of a different idea and warrants a post of it's own. These keys are in a circular pattern in the upper-right corner of the keyboard. Have you started making it yet? I agree that a flat KB is probably the way to go - most PC keyboards are flat, and use keycaps for profiling. Instead of directly mapping buttons to the calculator's buttons, you could probably achieve a nice QWERTY layout with a sensible calculator layout if you put a middle ground in place, like an arduino or something, it would convert the sensible keyboard layout to the calculator's standard layout. When do you plan on making a prototype? Keep up the awesome work NoahK! I see, looks like it's just test points. In this context, the [ENTER] key functions as the equal sign. I would love your feedback on some of these layouts, TI-84 Desktop Keyboard Calculator (TI-84 KE), Second example, and Second-to-last example, respectively, https://www.keebtalk.com/t/gb-keyi-84-mechanical-graphing-calculator-extended-1-week-till-6-8/8754, https://wikiti.brandonw.net/index.php?title=84PCE:Ports:A000, Cemetech Contest #24: Collaborative Safari, Last edited by NoahK on 25 Nov 2020 10:44:38 pm; edited 2 times in total, Last edited by NoahK on 24 Nov 2020 06:48:13 pm; edited 1 time in total, Last edited by NoahK on 24 Nov 2020 10:14:41 pm; edited 1 time in total.
