Help modding a Qanba Q2Glow to work on PS4


#1

So I am looking to mod my Qanba Q2 Glow EVO edition stick and I actually have a few questions about modding my stick in order for it to work with the PS4. I already understand that I’d have to purchase a PCB that supports the console natively like the Brook PS3/PS4 PCB, or the Brook Universal Fighting Board. Buuuuut…

My issue with the stick is not just getting it to work on the PS4, but to also get the LED buttons (and maybe stick) to work along with it. I’m not really asking for programmable RGB LED buttons, I just want the buttons (and maybe stick) to light up when I press it.

I was wondering if anyone could help me out on how the whole process can be done while retaining the same buttons and LEDs. Here’s an imgur album that has a couple of photos of the inside of the stick itself if it helps: http://imgur.com/a/xTE5n

Of course the idea is to spend as little money as needed while also making this project as simple as I can for myself. I’m not very experienced with electronics itself. I was thinking about making the original PCB be just for the LED functions of the buttons (basically turning the old PCB into an LED controller). Since the LEDs itself are independent from the button it relies on the PCB to tell it what to do. At least that’s what I think it does. It’s very interesting since the button and LEDs both have a separate connector, but in the end lead to the same connector on the PCB. Here’s a small diagram of the button and LED wiring: http://imgur.com/2FbJCQJ

Based off that, here’s an image of how I would assume the layout would work for one button: http://imgur.com/IH0hMAc. The problem now is how do I power both of the PCBs.

Can anyone tell me if I am on the right path and let me know if there is a flaw with my reasoning?

Could take the path of least resistance and just use a brook converter, assuming it works with the q2.

Ah, should’ve mentioned that I asked if the Brook Superconverter supported the Qanba Q2 Glow and was told that it wasn’t supported. Plus I would enjoy having the stick be PS4 native and not relying on a dongle.

I’ve dual modded my 360 Q2 Glow with the Brook PS3/4 Fighting Board, unfortunately the Qanba board needs power, ground and data + and - hooked up for it to power the LEDs, if you run just power and ground to it the board thinks “there’s no USB connection, I won’t drive the LEDs.”

The only way I can think of to get it to work is to get a separate LED controller, I can’t come up with a way to trick the Qanba board into seeing a USB connection when you’re using the Brook board.

Edit: Forgot to mention you could just run the correct voltage straight to the LEDs (I haven’t checked what voltage they are) but they’d always be on, unless you fit a switch. Personally I’d like to keep the light-on-press function.

So a little update on my situation.

I threw this topic onto reddit and got a response from Vicko. He helped me a lot with planning on how to make the LEDs light on press without using the default PCB and instead wiring it into the new PCB. Here is his little diagram that he drew for me nicely:

I then drew a diagram that included all 8 of the buttons and asked him to give me the ok. Turns out it will totally work out so here is the diagram I drew:

I’ll give an update when I finally get everything installed and will take as many photos as I can since I haven’t seen anything really on the Qanba Q2 Glow.
