I took an interest to this before, but god does this look difficult for us non- tech-savvy stick users. D:
So I’m planning to build a stick using the Cthulhu and the Imp with RJ45 connects AND LEDs (without batteries).
My question is LEDs will light up using the 5V from 360/PS3 USB, but what about GC or PS2? They wouldn’t without a battery, right?
They would work just fine from any console. Only from GC or PS2 they would be slightly dimmer due to the lower voltage.

hello all, i’m new to the forum but i need some help please. i just recently finished my mayflash arcade stick mod and i was wanting to know if anyone has been able to put any leds into theirs or if it is possible. i noticed when i was checking for contacts on the mayflash pcb that there is around 3.79 volts coming from a contact near the right side of the board where the snapins for my joystick are located. Will this be enough juice if everything is daisychained or do i need a battery? If i use a battery, will there be a way to use a hex inverter chip or am i stuck with just only the buttons lit up all the time as my only option? any help would be greatly appreciated since i have yet to find a mayflash mod with leds put in at this time. thank you

Power from GC should be 5v. THere is also a 3.3v line, but I never use it in either the MC Cthulhu or UPCB.
Hi,
I’ve made some weeks ago a little picture tutorial in my blog for the Cuthulu and Button Led Mod. It just works fine for me. Have fun with this stuff.

No resistors? Isn’t that dangerous for the LED?
sure, the resistors are soldiered directly under the leds
I think I am going to give this a try this week. Lights are pretty…
Im hoping someone can shed some light on what Im attempting to do and if it will work.
pin 14 is wired to my 5v source on the PCB.
pin 7 is grounded to the pcb, as well as the negatives from all 6 LED’s.
I have a six position barrier strip, on the 6 outputs I have wired the positive side of the led, positive from the buttons and pins 2,4,6,8,10, and 12.
on the input side of the barrier strip I have the actual wires sautered to the pcb, as well as the input(odd pins) from the hex inverter(1,3,5,9,11,13). All buttons match, so theres three output wires for each post and 2 input(one from the inveter and one from pcb).
I think I killed my pcb, as when I plug the controller in its freaking out right now, but is this idea correct or will it not work?
??? Why would you do this instead of following any of the directions here?
So you have outputs from the gates going straight back to the inputs of the gate? Wow. Don’t do that. The gate sees the input voltage is high, so makes the output low that makes the input low that makes the output high that makes the input high that makes the output low that makes the input low…
Im using screw in seimitsu’s and having drilled a hole in the button and having the actual LED inside the button prevents me from being able to replace a button without snipping the wire from the pos leg of the led to the inverter.
I am just trying to make this as clean as possible using barrier strips wherever possible.
edit: I figured out the problem, make sure to double check each “inverter” before you wire it up. I ordered a bunch of these which came in a bag, carelessly assuming my order was correct. It was a different model, so I took an extra one, wired it up and it finally worked correctly. damn you electronic goldmine.

big props to Michael from Kaytrims for not only the green case, but the shaft and balltop modding. The only thing I decided against in the end was setting the balltop to light up upon moving it in a certain direction but I decided against it as there wasn’t much room for the wiring as is.
I want this so bad on my TEstick, to bad im a retard on connecting leds and electric stuff ;(
Toodles/Tingboy: Am I to assume that the inverter method is still the safest (especially for dual mods) or is bencao74s method the faster, easier method of choice?
Bencao74: Is it safe to use this method with two LEDs per button?
I don’t see why using the inverter-less method would be hazardous to a dual PCB.
I gave up on this…buttons cost too damn much lol. I’ve got like 30 somethign buttons laying around my place, but none are transparent, except my Happs…which I don’t really like that much…
- :bluu:
i have been following the diagrams in this thread and having some trouble with the inverter method.
im trying to power the LEDs using the Madcatz retro pcb. A,LB,and RB buttons work fine but X,Y,B keep going off on their own.(not the LEDs, just the button commands)
i have only been trying one button at a time, it works fine with battery’s and with the other method without the inverter.
i have already wired up the inverter so prefer to go that way without an external power source.
any help would be much appreciated.
I think you may have switched the input and outputs on one side of the inverter. If you look at the diagram closely, the gates (the triangle+circle things) all face one direction, so if you wire one side up one way then rotate the inverter 180 degrees to the left, the input/output order is swapped. That’s a confusing explanation 
. I hope this suffices.
