 TI84 Plus CE Programs
 TI84 Plus CE BASIC Programs
 TI84 Plus CE BASIC Science Programs
These files are for the TI84 Plus CE, 83 Premium CE, and other "CE" calculators with color screens. BASIC programs are compatible with the TI84 Plus CSE and some BASIC programs written for monochrome 83+/84+ calculators will also work correctly. Assembly and C programs must be written for the CE calculators specifically; running them on calculators with an OS newer than 5.5 requires jailbreaking the calculator.

CHEMOS is meant to be an allinone chemistry helper. All of the equations included are ones that *I* have learned in high school so if there are any that I have not included but you may want me to add, just PM me. Instructions are fairly clear, but if any help is needed, there is a help page on the main menu.

This is a program for finding pH, pOH, [H+] (Concentration of H+ ions)/ [OH] (concentration of hydroxide ions). This WILL work on all of the TI84 series of calculators, untested on the TI83. All you need to do is input one of the values mentioned above, and the program will calculate the rest of the values. They are rounded to 3 decimal places, for ease of displaying on the TI84+ screen. If the values go offscreen, or look messed up, please report this by reviewing the file. I will get it fixed and reuploaded ASAP.
If you have any questions, comments or suggestions, PM me at cemetech.net or post a review on cemetech.net

Track any satellite in real time!
Categorized under:
Orbit84 allows you to see the path of a satellite in real time.
For example, with this program, you can find out if the ISS is currently visible,
or follow a HAM radio satellite to see if it's reachable.
This program uses many complex algorithms, such as SGP, to find the precise position of a satellite and display it on a beautiful color map. 
Compute the molar mass of any compound, including those with parentheses! Can calculate the molar mass from chemical formulas of practically unlimited length, including those with multiple digits of subscripts and those with parentheses nesting up to 998 times! Also features a silent mode for BASIC program integration.

This Program will allow you to take full advantage of the clock, date, and timer features of our caculator, without needing to know any of the tedious syntax for the functions. It allows you to Set the Time and Date, view a realtime clock, use the built in timer, and preform many complex calculations, including:
finding the Day of the Week
converting a large amount of seconds to Days, Hour, Minutes, and Seconds
finding the amount of days between two dates
and much more!
This will NOT work for TI 84Plus CSE, as the menu bug (seen in the screenshots) will make it very hard to useSorry about the error bug in screenshots,I had to use a TI84 Plus CSE emulator, and those still have the menu bug. THe program looks fine on the 84 Plus CE, however.

Nuke Simulation is a very involved and fun program. It is a program that simulates detonations of nuclear weapons, and you can view to see what it takes to detonate a certain area. There are many different types of bombs, and you can blow things up from a small towns to entire universes! I hope you like this program!

This software is made by JustinYD88 (cemetech.net). You may distribute this software, provided this notice is included. If the software has been edited in any way, please provide appropriate notice.
This program simulates gravitational interactions with m1*m2/d^2 and F=ma. The demo is included in the program, but you can make your own gravitational configurations by editing the [H] matrix and loading it with the 'LOAD [H]' option.
Matrices are used to represent the objects. Each row represents an object (up to 99, the matrix limit) and each column represents a property of that object.
Column 1: The mass of the object (negative masses work too)
Column 2: The current Xposition of the object
Column 3: The current Yposition of the objectColumn 4: The current Xvelocity of the object
Column 5: The current Yvelocity of the objectColumn 6: The previous Xposition of the object (used for drawing lines, internal use)
Column 7: The previous Yposition of the object (used for drawing lines, internal use)Column 8: If circle drawing is enabled, this is the radius of the circle. (If you leave 0, the radius will be (3*mass/4pi)^1/3).
Column 9: This is the colour used to render this object's circles and lines.This program uses the [G] matrix for internal data manipulation, and the [H] matrix for importing configurations.
Included in the ZIP is the program file, one custom configuration, and two screenshots.

In messenger RNA, a set of three bases called a codon code for one amino acid. With 64 combinations of bases and 20 different amino acids, memorizing what codes for what is impossible and why use a weird, hardtoread paper chart when you could use your calc! Just use the arrow keys to change the bases and the amino acid abbreviation will appear magically before your eyes! This might work for the Ti 84 Plus but I have not tested it yet.
(Disclaimer: requires a small amount of understating of how codons work.)

With this program written in TIBASIC you can calculate the day of week for any given date!
When you try to calculate on what day of the week a date was using the DayofWk( command, you might have noticed that the answer wasn't correct.
I don't expect you'll have seen that though, but I've tested it with several dates and I can tell you it isn't correct.
If you want to know more about this, you can read the 'readme' file.I've in this program made a settings part, in which you can set everything for your country.
I really want to thank one of my classmates, who can calculate a day even out of his head, also for the Julian calendar.

This program takes a measurement (a value and a metric unit) from the user, and provides the user 2 pages of 10 or 11 conversions of the initial value, making it convienent for the user to find a converted measurement they are looking for. Supports all the way from yoctometers (ym)/yoctohertz (yHz), to yottameters (Ym)/yottahertz (YHz). (The user can specify the unit of measurement.) The program is very small and relatively fast! Make use of this if you have science or math homework!

This program is designed to help students and enthusiasts understand orbital mechanics and the influence of mass and gravity on orbiting objects. Formulas are provided for all calculations and constants programmed for the Earth, Moon, Mars, Jupiter and Kerbin. You can also input your custom object mass/radius and gravitational constant to calculate orbiting variables. You can complete calculations using velocity or height as a known variable. The calculator will show missing information, including the period and circumference of the orbit. Calculations are purely theoretical and assume a perfectly circular orbit. However, reallife calculations make sense with the calculator (check out the ISS, which orbits at ~407 km above the surface of the Earth at a speed of 7664 m/s and an orbital period of 92.7 minutes).
The program is not tiny because it was made to be pretty and easy to use and understand.

This handy program calculates the safe stopping distance (which aids in determining a safe following distance) of a vehicle travelling at any km/h speed. You input the reaction time in seconds, the vehicle's speed, the roadway's grade (+/), and the friction coefficient. From this data, the calculator gives the user the distance travelled in the reaction time (before any brake is applied) and the distance travelled with braking. You also get the sum of each, which is the total safe stopping distance of the vehicle.
This is a good tool for beginner drivers and for professional drivers who want to improve their skills on the road. You can also tinker with the formula and see how much reaction time and paying attention while driving impact the distance your vehicle travels if you have to stop suddenly.

This simple program calculates the theoretical hull speed of a sailing vessel measured in feet or meters. You decide your unit of measurement and input the LWL, and the calculator will give you the theoretical hull speed in knots.
This is a great app to have if you are looking at purchasing a new boat and want to know how fast the hull is capable of travelling in the water. It is also great if you are a professional mariner and wish to settle a bet about your ship's poorly designed.
Fair winds and following seas!

This small program uses the rocket equation to calculate the deltaV of a vehicle using exhaust velocity as an input variable. It is excellent for students and enthusiasts to understand better how a change in mass over time impacts the change in velocity of a rocket. The equation is purely theoretical and does not consider things like air resistance. However, the theory is sound, and the app is a great way to begin understanding the complicated rocket equation.
