GrizzlyTime
GrizzlyTime is a JavaFX application that Grizzly Robotics uses for logging
student/mentor hours. It takes roughly 5 minutes to get working on a new
system (assuming Java 8 pre-installed).
Features:
Automatic Student Registration
Cancellation of daily hours if user forgets to logout
Individual tracking of daily hours
QRCode/Barcode compatible scanner to scan student IDs (configurable)
Text box to manually enter student IDs
GrizzlyTime does of course have a few cons that will be addressed in the upcoming weeks.
GrizzlyTime cannot, without modifying code, do:
Do your homework
Wash your car
Work without internet (requires google sheets)
Change default fallback image (TODO)
Automatic updating (TODO)
GrizzlyTime is specifically setup for incredible ease of use.
All you need is a Java 8 machine (Java 11 coming later).

Tutorial:
GrizzlyTime is organized into three sheets.
Sheet 1 is for overall hours, as well as any contact information for students.
Sheet 2 is for calculating average student hours and other formulas.
Sheet 3 is for storing individual dates and respective hours for students
Here’s a sample image of the main page. Some student data has been censored to respect privacy.
As always, our code is open source and we welcome any contributions you wish to make.

PS: If things happen to explode or cause thermonuclear war, I’d greatly appreciate if you create an issue on the GitHub page https://github.com/Daltz333/GrizzlyTime-JavaFX so we can create a fix pronto.
Do you recommend running this off of one dedicated computer where students go and clock in/out, or do you have each student run it individually?
Our school doesn’t really do ID (we have them but nobody actually carries them). Is there anything from stopping us from just assigning each person a unique number? Is there any required length of the numbers?
Just installed. The splash screen says to use birth date MM/DD/YY in place of an ID. So it looks like 6 digits is required in the code. I’m sure you could supplement with another number of student choosing.
Any 6 digit number will work. You can absolutely use your own numeric system if you’d like.
Also my team has a dedicated login laptop for this. I personally don’t recommend every student having their own laptop for it. It’d be quite a pain to authorize the application on many laptops. Also if a student was tech savvy enough, they could de-compile the Jar, modify it so it gives them X number of hours, recompile it and the credentials will still be valid.
If you are bothered by the camera, it can also be disabled/enabled via the config.json. It’s also possible to change the fallback image from the Grizzly logo to some other image, although you will have to build the program from source and grab credentials from https://developers.google.com/sheets/api/quickstart/java.
Sorry about the lack of instructions on building it from source. Will provide more at a later date. Feature requests/UI changes are absolutely welcome.
Customizable, all images can be replaced without modifying the code
Hands-Free Mode! Compatible with USB Scanners
Full Screen Mode
Experimental Mac Support
Configurable via a JSON file
Logs individual dates/hours sumative
GrizzlyTime can be used for monitoring student growth over years, gathering team ethnicity, sex, average age, etc. Code can be easily extendable for gathering these kinds of statistics!
Is there a view of everyone currently signed in? Could you add a feature that allows you to explicitly select which action you are doing (sign in/sign out) in the form of a toggle or radio button so that those who are absent-minded (me) don’t have to worry about whether or not they actually signed in?
