Published by Michael2_3B on April 17, 2018 at 4:33:05 PM CST | Discuss this article (2)

It's that time again, time for the 9th PotM article in a row! It may seem like a lot, and it certainly is, but we are almost caught up with these! So without further ado, here are the projects of December 2017:

  • BOSshell for the TI-84+CE Development thread: beckadamtheinventor has created an epic new shell for the TI-84+CE, in the ICE language! BOSshell, which stands for "Beckadam Operating System Shell", will be capable of many of the things you'd expect out of a shell: file and folder management and editing, file importing, various subroutines, and more! We would love to see more of this project.
  • Catch Color Stars: goldeneternity's project "Catch Color Stars" is a fun smartphone game to play when you're bored. The goal is to catch falling stars with the matching color block, and if you mismatch the star and the block, you have to restart. Go check it out!
  • CE Video Thingie: This month, Cemetech user Iambian worked hard on his "CE Video Thingie"! With the capabilities of playing videos (kind of), Iambian has improved it to have higher resolution, better playback and better encoding. It looks like Iambian is making a lot of progress!
  • Dragon Warrior (-ish thing) on the CE: Pieman7373 has decided to remake his popular Dragon Warrior game for the CE in C! There is a cool new screenshot at the end of the thread, so go check it out!
  • FlowCE [C for TI-84+CE]: From jonbush, FlowCE is a fun game based on the popular smartphone game "Flow Free". Programmed in C, jonbush has been hard at work this month adding more features and controls to the game. More information can be found in the thread.
  • Hexicity CE: beckadamtheinventor has started a fun new game, which supposedly will be similar to "Sid Mieir's Civilization V." In essence, it will be a hexagonal tile-based civilization simulator. There are no screenshots yet, but it looks like a great idea!
  • KryptonIDE - A better program editor for the TI 84+ CE: KryptonicDragon has made significant progress on this editor this month! As seen in the thread, he has added syntax highlighting, editor themes, different modes of typing, and more! We would enjoy seeing more of this project, and it looks like it is nearly complete!
  • Latest News on Star Trek: ACagliano has been working hard adding improvements to his game, which is nearly done! There are cool graphics, battles, and all the fun stuff you might expect from a Star Trek battle. Go show ACagliano some love and support, and if you can, help him debug!
  • Life Simulator: As seen in the title, Life Simulator is a game that simulates life and all of it's decisions. Created by 21tmccauley, it looks like it will be a great game! Go show 21tmccauley some love and support!
  • Calculator Hoarder: This month, Cemetech member Michael2_3B created a cookie clicker style game in javascript, except it is based around gaining calculators. There is a link to the game and the repository in the thread, so go check it out!
  • NOS - A alternative shell: Yet another shell, this time created by The REAL LAX18, "NOS - A alternative shell" is a shell for the TI-84+ CE capable of organizing and executing files, and more. Though the project is currently idle, according to the creator, it looks great nonetheless! Check out the screenshot in the thread.
  • Quiz Viewer and Creator (TI-BASIC, TI-84 PLUS CE): dankcalculatorbro has been creating a simple quiz viewer and creator in TI-Basic. Though there are no downloads or screenshots yet, it sounds simple and useful, so go check out what he has in mind in the thread!
  • UniChat!: _iPhoenix_ has been working hard on his security measures and other features for his chatting site, which is a "free, simple, and open solution to a problem exactly none of us have!". UniChat is an extremely simple chatting service using Google's Firebase platform, so go check out the thread to see it for yourself!
  • [TI-84+CE] Offline Bitcoin Wallet: As the title suggests, SopaXorzTaker has created a cool new Offline Bitcoin Wallet for the CE. It is capable of generating and storing addresses and private keys, and can create qr codes for the file. It looks cool, especially if you're interested in bitcoin!
  • [TI84+CE] Virtual3D : A full assembly 3D engine: This month, TheMachine02 has been hard at work on his 3d engine! There has been optimization, small feature additions and more which make the engine all the more incredible. Go check out the new screenshots and information in the thread!

And those are all the wonderful projects of December! There were plenty of great projects, as always, so be sure to at least glance at each one. In addition, I encourage you to vote for your favorite completed project. Surprisingly, there were only 2 completed projects this month, so it might be a bit of a tough competition! We'll see you all again soon in next month's article.

We accidentally forgot to add JPL to the November poll, so that's why that program is in this poll, even though it's not finished in December. You can find it here: http://cemete.ch/t14186.

Projects of the Month: November 2017
Published by _iPhoenix_ on April 14, 2018 at 5:39:11 PM CST | Discuss this article (2)

Hello, everyone! This month was super busy, with lots of new programs being worked on while everyone was (presumably) almost settled back into school. Here are the contenders for the month of November:

  • Asteroids CE v.1.8: The REAL LAX18 made a cool game where you have to shoot or avoid "asteroids" coming at you! You can find directions on how to get the file in the thread.
  • BOSshell for the TI-84+CE: BOSshell for the TI-84+CE is an attempt to make a shell in ICE created by beckadamtheinventor. He plans to add many cool features, and even created a demo, which you can find in the thread! We cannot wait to see more of this project!
  • CE Video Thingie:†From Iambian, CE Video Thingie is a thing designed to do the stuff with video for the CE calculator. It is able to play short, somewhat low quality video clips (it's very high quality for a calculator!) on the TI-84+CE graphing calculator. Iambian is working really hard to increase the quality and length of the video you can view with it. Be sure to check out the thread for future updates and demonstrations!
  • Dungeons & Dragons [BASIC] [TI-84 Plus CE]:†TheLastMillennial is trying to port a version of the popular game Dungeons & Dragons to TI-BASIC on the CE. We wish him the best of luck and would love to see more of this project.
  • FlowCE [C for TI-84+CE]:†FlowCE is a port by jonbush of the mobile game "Flow", which is a game where you have to connect two dots with pipes that cannot cross.† More information can be found in the thread.
  • ICE On-Calc Sprite Editor (Huge update underway): CalcMeister added some cool updates to his on-calc ICE sprite editor this month. Though he previously lost his source, PT_ was able to decompile it manually, and CalcMeister made some great visual changes. Check out the thread for a download.
  • JPL: A game for Color and Monochrome calcs!: TheLastMillennial started work on making what was on of his CC20 entries even better! Without changing anything, his program works on both the monochrome and color calculators, which is impressive already. We can't wait for new updates!
  • Jumpman for TI 68K Calcs: Ranman added a bunch of improvements to his port of Jumpman! These include optimizations and bugfixes.† You can find the complete list in the thread!
  • KryptonIDE - A better program editor for the TI 84+ CE: KryptonicDragon's project "KryptonIDE" is a redesigned program editor for the CE. He added a truckload of new features this month! More information can be found in the thread.
  • Symbolic Derivative Solver for TI 84+ CE:†Cemetech newcomer squishy created an amazing project! As the title suggests, it is able to quickly solve derivatives (returning a function, not a value, unlike the TIOS version on the 84+CE) harnessing the power of C! It is really easy to use, too. Go check out the thread for a download (including source) and usage instructions.
  • The Oregon Trail CE [ICE] [Release 1.0]:†OldNewTimer finally released a version of his port of The Oregon Trail to the Archives! It looks interesting, so go check the thread out!
  • UniChat!: _iPhoenix_ "created a a free, simple, and open solution to a problem exactly none of us have!". It is an extremely simple chatting service using Google's Firebase platform, and it looks really cool. Check out the thread to see it for yourself!

The poll (and inherently voting) is now open. This month is highly competitive, with several very good entries! Happy voting!

Projects of the Month: October 2017

I hope you're not tired of all the PotM's, because here's another one! Again an impressive list, so let's see what everyone made that month.

  • Cerkel Snek: Iambian created an upgraded version of the traditional game Snake for the CE, called Cerkel Snek. In this game you are a snake and you have to eat the big circle, but the main difference with Snake is that you have radial movement, which means the snake is more flexible. The screenshot looks amazing, so go take a look.
  • Color Switch (Axe): Switchblade recreated Color Switch in Axe using greyscale instead of colors. If you still have your monochrome calc, grab it and try this game!
  • Falldown: Iambian created another nice game in C, featuring a ball falling through floors until you hit the top. A screenshot in the thread explains how the game works. How far can you go?
  • FlowCE [C for TI-84+CE]: jonbush and earthnite decided to program their CE port of Flow Free in C, instead of BASIC. This resulted in much better graphics an performance. They also added 200 levels, hopefully enough for some fun hours of connecting dots with each other!
  • Gateway to Legend: 123outerme continued working on his new game, Gateway to Legend, a Zelda-like RPG. He posted a few YouTube videos in the thread with progress updates, so if you don't know what it is or want to know at what stage the program is, go check it out.
  • ICE On-Calc Sprite Editor (Huge update underway): CalcMeister ported his ICE on-calc sprite editor to ICE v2.0, including more features. At the time of writing, it's not finished, so check out the thread and motivate him to finish it!
  • KryptonIDE - A better program editor for the TI 84+ CE: Good news for everyone who's tired of the slow and awful OS program editor! KryptonicDragon has started on his own IDE, KryptonIDE, where you can view and edit BASIC/ICE programs. It includes syntax highlighting, indentation, copy-paste and much more, so I'd love to see it finished!
  • Sorcery of Uvutu PC Port: 123outerme has finally official released his PC port of Sorcery of Uvutu. The video, which he posted as well, looks pretty nice, so definitely give this a try, whether you have Windows or Linux or whatever.
  • Text to Morse Code! (with screen flash) [TI-84 Plus CE]: Do you ever want to learn Morse Code and want to receive/send it, but you don't have a light and only a calc? No problem, TheLastMillennial made an on-calc program to input morse code and see the text. Using an assembly snippet, the brightness can also change like a real light.
  • _iPhoenix_ís unloved programs.: _iPhoenix_ has made a bunch of 'unloved' programs, like Stick Hero CE, Avoid and iBase, which are actually quite nice. Just try out each program and judge yourself.

That's it, folks! You have again 10 days to vote in the poll, so don't wait too long. We're pretty nice catching up with those PotM's, only a few left until we're on scheme. Thanks everyone for their projects, and keep developing them!

Projects of the Month: September 2017
Published by Michael2_3B on April 12, 2018 at 8:30:08 PM CST | Discuss this article (2)

Welcome back to another PotM article! This month we are covering all the wonderful projects of September, of which there were several completed ones. Here is everything that we saw this month:

  • Agar.io+ [Agar.io Expansion for PC]: Battlesquid has been working hard this month on his own version of the popular online game agar.io. Agar.io+ is a wonderful new expansion/take on the game, so go check it out! There are screenshots and download links in the thread.
  • Connect 4 for TI-84 Plus CE: tqbun, a new member, has delighted us with his own version of Connect 4 right at the end of the month. Featuring an artificial intelligence to play against, and a multiplayer version which should be coming soon, this one's definitely worth a look.
  • Fishy and Scogger ported to the CE: Iambian has successfully ported both his Fishy and his Scogger game to the CE, from the 83+ and the 84+ CSE (respectively). In Fishy CE you must become the biggest fish in the sea, while avoiding larger fish, and in Scogger CE you must hop over lily pads and land at the last one with no lily pads left. They both look like fun games that are worth a play!
  • New Rpg in progress: Switchblade has been hard at work at his own top-down RPG for the 83+/84+. While there is no name for the game yet, it looks like he is making good progress!
  • Smart Geocache: salehAce has started working on a "Smart" geocache, in which you complete certain tasks or puzzles in order for a lock to open up. There is more explanation in the thread, and even some videos!
  • Sorcery of Uvutu PC Port: 123outerme has completed his port of Sorcery of Uvutu to the PC. It is very similar to the calculator version, except now you can actually play it on your own computer! There are some wonderful downloads and screenshots in the thread.
  • Travis's assorted smart light scripts: Travis has created several lighting scripts in python, which can control the hue, brightness, etc of various LED lights. This one is an awesome project because if you have your room set up with the appropriate hardware, you can create almost any mood you like.
  • Calkusudo: Nik has come up with a wonderful new Sudoku game for the TI 83+/84+ monochrome calculators, and it is 100% programmed in TI-Basic! If you are up for a challenging game of sudoku, or even want to look at the code for the game, you will not be disappointed.
  • [TI84+CE] Virtual3D : A full assembly 3D engine: TheMachine02 has blessed us with incredible screenshots and explanations of his wonderful new 3d engine, developed for the TI-84+ CE, and using the powerful ez80 microprocessor. While it's not completely finished yet, there is already significant progress beyond your imagination!

And that's it for September! 6 of the projects listed here were completed this month, so be sure to vote for your favorite one! We'll be back soon for next month's article.
