Connect-4
|
|
|
Version: 1.00
Size on Calc: 3409
An impressive remake of Connect-4. Features fast, streamline graphics, and a 1-player engine with AI. Based on "Connect 4-5" for the TI-89. Play a game against the calculator, against a friend, or watch the calculator play itself. You can play the game in Drop Mode (like normal Connect-4) or Tic-Tac-Toe style. Also features a "Show Thinking" option, allowing you to see the positions the calculator thinks about when it moves. You can also change the connection length, allowing you to play "Connect-3" or "Connect-5" in addition to traditional Connect-4.

A powerful base conversion utility. This converter supports any base from 2 to 36, and can handle numbers nearly 7-bytes (0 to 17592186044410) in size! Best of all, it's undoubtedly the FASTEST base converter for the 83 Plus.

Key ShortCutter
|
|
|
Version: 2.00
Size on Calc: 6203
A shell where the most important thing is that you shouldn't have to press many keys to run your programs. Learning how to use this new, innovative shell requires some effort. But once you've got the hang of it, you'll find KSC is a fast, powerful and nifty utility. Some of the features include folders for organizing your programs, and a TSR, which allows you to suspend execution of programs and save a screenshot, adjust contrast, and much more...

Upcoming Programs
|
|
A periodic table (currently untitled)
|
|
|
Platform: TI-86
Estimated Size: 4500 bytes without modules, 7500 with modules
Designed so that you choose the data you want. Perhaps you don't need the boiling and melting points for all the elements, then simply don't load that particular module onto your calculator, and you'll save 650 bytes. Every type of information is stored in a seperate file.
Here are some of the features:
Data contained in modules
You can create your own module
Graphical table
Any number can be stored to a real variable
Here are the current modules made so far:
Names
Atomic mass
Common oxidation states
Electronegativity
Melting and boiling points
First ionization energies
Resistivity
If you know of anything else that should be made into a module, please e-mail Leif.

Matrix Solver
|
|
|
Platform: TI-83 Plus
Estimated Size: 16384 bytes (1 ROM page)
This is undoubtedly my biggest project to date. It will be released as a FLASH Application, and I hope to implement key hooks that will allow for quick access to the application. Once you have this application installed on your calculator, you won't need the old TI-OS matrix functions anymore, as this application includes all the same functions, plus many more that the calculator feature. Unlike the normal TI-OS matrix functions, Matrix Solver doesn't just give you an answer. It provides step by step analysis of how to solve the problem and work a solution. All workable calculations are displayed in a sleek, user-friendly format.
Matrix Solver will feature the following functions:
Determinant
Identity
Inverse
Cumulative Sum
Scalar Multiply
Matrix Multiply
Area of a Triangle
Systems: Inverse Matrix
Systems: Augmented Matrix
Systems: Cramer's Rule
Systems: Elementary Row Operations
Systems: Row Elchelon Form

Drawing Tools
|
|
Platform: TI-83 Plus
Estimated Size: approx 2000 bytes
This is a nifty little drawing utility you can use to make designing your programs or pictures on the calculator easier. It allows you to quickly manipulate your drawings without the hassle of having to do it all by hand. This program is not intended to be used for he entire drawing process, but rather to be used as needed.
Drawing Tools will feature the following functions:
| Fill Rectangle |
Insert Rectangle Border |
| Clear Rectangle |
Flip Rectangle Horizontally |
| Invert Rectangle |
Flip Rectangle Vertically |
| Move Rectangle |
Rotate (90,180,270) |
| Copy Rectangle (and paste) |
And more... |
I already have the fill, clear, and invert rectangle functions working perfectly. I just need to come up with an efficient routine for copying a rectangle. I'll post updates as work progresses.
