Final Fantasy 9 King Of Jump Rope for PS1 version

FF9-KOJR

Story

Getting back to FF9 because FF7 RMK is out here, but I don't have PS4 :(

I'm still really bad at FF9 Jump Rope minigame so I was looking for fun ideas on YouTube. Found this https://www.youtube.com/watch?v=Z9EJICJh6oQ with GitHub link https://github.com/mikelhamer/kojr .

Well, I don't have a RaspberryPi at home, but I have an Arduino.

Done some research on how to link an Arduino with a Solenoid: https://core-electronics.com.au/tutorials/solenoid-control-with-arduino.html

In the video he explains that he can't go over 700 so i think that the timing must need to be tweaked. So get back on GitHub i found this: https://github.com/septomor/FF9-Jump-Rope-Script

Well, i hope that the timing is correct, now just need to wait and let's jump :)

How to use it

• Prepare your electronic setup.
• Put everything in place.
• Place yourself in front of the little girl.
• Launch the program.
• Wait about 10 minutes.

Electronic

Required components for this project:

• 1 x Arduino Uno
• 1 x Solderless breadboard
• 5 x Jumper Wires
• 1 x 220 Ω Resistor
• 1 x Diode (1N4001)
• 1 x Power Transistor (2N3904)
• 1 x 5v Solenoid or this one, if the first one is too small

Setup

Case

Fusion 360

Third Revision

Well, why not use Thingiverse and just make a platform:

• A small case for the Solenoid + paper:

• A Stand for the controller maybe?

Print the controller Stand, then adjust the height for the Solenoid, looks to be a better option!

Second Revision

Well, why not use Thingiverse and just make a platform:

• A small case for the Solenoid:

• A Wall Mount for the controller:

Still need to adjust everything, still not good for me :/

First try

Yeah, it's not really good :'(

Need to adjust everything, so maybe 2 or 3 prints, better forget this one.

WIP

• Arduino code -> 16.04.2020
• Electronic setup -> Looking for free Fritzing -> 19.04.2020
• First test -> Buy components -> Components incoming
• Timing tweaked
• 3D case first try -> Discover Fusion360 -> Update case -> 20.04.2020
• Print case -> Buy 3D Printer -> Wait -> Discover Slicer
• Adjust case
• Complete test
• Final commit with video

Notes:

Hacking the controller way

Well, if I can't build the solenoid way, why not just hack the controller?

With some work I think it's possible to directly send inputs to the PS2.

Links:

• https://store.curiousinventor.com/guides/PS2 Build a link between the Arduino and the Male connector should be possible i hope.

• https://github.com/madsci1016/Arduino-PS2X Instead of reading the inputs I think it's possible to send them.
