Kaimana RGB LED Board thread, RGB animations and more! SRK Tech Talk 2013 Product of the Year!

It only handles indexable LEDs.

What about using an adapter?

I guess then you could maybe use a bunch of Kaimana J adapters but even then it would be wonky to code (controlling ground for the correct Cathode on each light based on how you wire them) But that’s really overkill for somethings like this given those are solid color LEDs. Just wire them direct to 5v and GND as they are intended.

Got strobe and breathing animations working. Now to further experiment!

@ChaoticMonk as Jasen mentions you should just make a led harness that connects straight to 5v.

Thank you both.
Any chance you know of a good reference for this? I’m still an amature when it comes to leds and can’t wrap my ahead around how 10 5v leds can be lit by a single 5v source lol

Daisy chain them like a ground daisy chain.

Which hollow shaft should I buy for the Hyabusa/will the stock one allow for a led to be put into it?

Well these are a few animations I got working. The breathing animation was by far the most interesting one to build. Who knew I would make use of my Trig classes someday?

@JRDIBBS Awesome job man! Can’t wait to see what other animations you come up with.

Just ordered one of these for my Hori Fighting Edge with Brook UFB, can’t wait to try it out.
Although, I do have a question, has anyone tried using one of the recently popular RGB Strips for PCs?
Some Asus motherboards have a header labled 12V, G, R, and B for these LED strips.
Thinking if it’s possible to replace the blue and red leds from the side of the fighting edge and replace it with these strips :stuck_out_tongue:

Edit: Or maybe just use the small joystick LEDs that Paradise sells?


Although it does say it needs a resistor, I unfortunately don’t have soldering experience

I have problems with me set up, i use http://brightstick.freecade.org/ to set up my buttons.

i can set up Joystick led, p1,p2,p3,p4,k1,k2,k3, but K4, SELECT, START and HOME each buttons has 2 different colors how can be posible?

also i want to add a extra buttons total 12 buttons and joystick led but i have no idea how set up the extra button.

Im using Kaimana mini and J2.

this is the code looks like for buttons:

#define LED_P4 16
#define LED_P4_B 17
#define LED_P3 14
#define LED_P3_B 15
#define LED_P2 12
#define LED_P2_B 13
#define LED_P1 10
#define LED_P1_B 11
#define LED_JOY 0
#define LED_JOY_B 1
#define LED_K4 2
#define LED_K4_B 3
#define LED_K3 4
#define LED_K3_B 5
#define LED_K2 6
#define LED_K2_B 7
#define LED_K1 8
#define LED_K1_B 9
#define LED_SELECT 22
#define LED_SELECT_B 23
#define LED_HOME 20
#define LED_HOME_B 21
#define LED_START 18
#define LED_START_B 19
#define LED_COUNT 24

Any help would be appreciated

I am actually looking into this, all you need are INDEXABLE LEDs so start from there.

I think we could setup a standard troubleshooting format, but for now please send over the order in which your leds are connected starting from the Kaimana. eg

Kaimana ->K1->K2 ect…

This and the Joystick LED only needs the value already defined in the default code brightstick generates.

Thanks for the response, this led me to some LEDs online:https://www.sparkfun.com/products/12025 but at $20 for 1 meter it doesn’t seem too worthwhile.
Maybe when prices go down, or if there’s a smaller lenght. For now 1m seems to be the smallest, of course you could cut it, but you’d have to solder the wires onto the two other ends.
Should also note, that it also includes two additional wires not on the JST connector for power, so this may not even work for our application :confused:
Grabbing some plain LEDs seems like a more viable option

I finally found my mistake , the joystick only uses a LED, so it is only LED_JOY 0 , do not know why I thought it had to be used as 2 leds if it is one.

This is my diagram. yours may vary depending on where you start . I hope this helps you. =)

Thanks to JRDIBBS for helping with the code for the Pandora stick I built some time ago. Customer wanted a pcb upgrade to the Universal fight board and kaimana led kit.

Case leds light up Purple with buttons light up white and red on activation.

That looks pretty fantastic

hey guys, need some help with the most recent kaimana j2 3" harness. i’m attempting the connection from the very last button on my kaimana mini + j2 (x8) setup, to a neopixel ring (somebody did this and @ā€œJasen Hicksā€ explained in length on how the code should go many many pages ago on this thread, iirc).

however, i have no way of knowing which wire from the harness is data, vcc, or ground. there are 3 wires coming from the 3-pin end and going to the 4-pin end. i need to cut one of the ends and extend the wires to solder to the corresponding solder joints on the neopixel ring. any advice?

Well, I’m not sure on the j2s but on the j1s you have the labels on the pcb din or dout vcc gnd.it should go from a dout out the J to the din on the neo. I have one at home but no time to put something together lol.

Grab your multi-meter and probe the pins. You should be able to find 5V and GND very easy, leaving only the DATA OUT line. Here’s the datasheet for the WS2812B LED on those J2s:
