When my kid gets her claws off of me, I’m going to take some time and write up a diagram about what you’ve said here. It makes sense looking at it, I just need some non-child-in-my-face time to process it. Yes, it’s all going into one control panel, 30" long by 6" wide by 2" deep. Each player gets 6 action buttons on the face, 2 auxiliary buttons on the side, and 1 start button in the middle each. so 9 per player.
So in trying to make matters simple, if I divide the Kaimana in half and I’m daisy chaining these Kaimana J’s together, what about the last LED, does it remain blank?
@armi0024 I’ve got a PS3 with two MC Cthulhu’s attached all stuffed into a custom built cabinet. Going with what @DJYin said I’m assuming that after the LED harnesses are daisy chained, how does the Kaimana determine which button is which? I figure that a wire goes from the Roundhouse on the Kaimana to the Roundhouse on the Cthulhu but then how does that translate to the LED? Should they be daisy chained in a specific sequence?
You can either put the kaimana inline with the signal or just jump it. If the cthulu has screw terminals, you can just run the wires into one side of the kaimana and then go from the other side to the cthulu. You can do this for 15 pins or inputs, and because it is open source you can use whatever inputs you want.
As for the LEDs you can hook up as many as you can power. You van only associate them with 15 input signals, but you can have buttons like select/home light up without responding to touch.
OK, I’m going to try and write this down and see if it’s correct; bear with me as this may be a Tim Taylor moment. My cthulhu’s have screw terminals so I’m good on that front. Also I’m looking at this Kaimana like it’s able to support 2 different players, is that correct?
Well in the case it is, I have one ground wire going from the button to the cthulhu’s ground terminal. Next I have a signal wire going from the cthulhu to the button and a second wire going from the same terminal on the cthulhu to the corresponding one on the kaimana. From there the harness going from the kaimana to the kaimana led on the button. What I’m trying to figure out is how does the kaimana know to light up that specific button upon being pressed, I know that the signal wire links the cthulhu and the kaimana to the button but I feel like I’m missing a step in the wiring process whereas the kaimana links to that specific led in the chain. That or I’m going about this completely ass-backwards.
Sorry for being a headcase, I drew up a diagram so you can see what I’m seeing.
@Armi0024 I see the adapter on the site but how does it work with my IL LED’s? will I have to get 1 adapter per LED? or will the adapter connect to my sparky and I just pass through that. I know you’re busy so whenever you get a chance let me know.
I’ve read the wiki but I stil don’t quite understand how to get power to the board. It says that the two right headers in the plugin are 5v but I don’t grasp how to power it with that. Also to hook up pele’s all I have to do is daisy-chain the adapter boards together and use the jumper adapter to connect them to the adapter boards right?
You’ll have to get a vcc line from your stick’s PCB and tap it into an available vcc point on the Kaimana (uppermost right or left terminals when viewing the picture), which will carry the required 5v from the USB connection throughout the Kaimana.
If you are powering 11 or less LED’s (like any standard Fightstick), I believe that armi has said should not cause any issues with using just the power from the USB line. For a large number of LED’s, you might need to get a dedicated 5v power source to plug into the Kaimana.
EDIT: using a PS360+ as an example, if you take a wire from the vcc terminal on the PS360+ and connect it to the Kaimana, Congratulations! You’ve just provided power for your Kaimana. Remember that the terminals were designed as a Passthrough to the PS360+, so your button connections would all go to the Kaimana, then on the opposite side, you would take those same terminal connections (including at least one GND and the vcc) and wire each up to the corresponding terminal on the PS360+.
EDIT2: OK, I re-read the wiki, and apparently, you DO have to tap a 5v header pin from vcc as indicated in the wiki diagram, or directly into the 5v line of the harness somewhere. Not sure why, but perhaps one of the beta testers can elaborate.
Begin by soldering a wire from the VCC terminal on either side of the Pass Though Terminals and solder it to either of the right two terminals that begin the chain on the bottom of the PCB:
Then begin your chain from the kaimana to the first Kaimana J or Pele adapter board.
Remember to adjust your code based upon the first action switch in the chain. I can elaborate on this once your setup is complete.
The reason you need to tap VCC is to supply power to the chain, as it is not directly connected to VCC, hence the lack of power.
If I use screw terminals on both sides can I just use one of the kaimana wire harness. Take one of the wires that goes to the 5v and screw it into the vcc slot.
It seems I missed a few things actually. You would need those for the Pele to connect to the adapter board. Let me make a list real quick of what you need.
Pnoy, thank you
Here is a simple diagram… very simple, sorry for using paint
For Peles you will need a Pele, adapter harness, adapter, and Kaimana harness for each button you want to light up.
You also need adapters for the Joystick or legacy LEDs…
