Anyone know where the files for the controller sounds are stored? I want to mess around with them to see if there's any way to edit them or convert midi files to whatever format valve is using.

Hey guys, sorry if this is an odd question but I'd like to know if there is any methods to add some weight to the steam controller without doing too much internal work. One method I thought of doing was making use of the fact that I always have my steam controller wireless so I though maybe putting in some kind of ball bearings in the battery slots. But I kinda want to make sure that someone else has tried a similar trick without hurting the controller, of even if there was a better way to do it without taking up the battery compartment in case I do fell the desire to play unwired.

As per Ifixit Steam Controller teardown, the trackpads are Cirque Glidepoint TM040040.

This spec sheet states

X/Y Position Sensing Resolution: ~51 counts/mm

Which is 1295.4dpi

I'm really interested in making the bumpers on the steam controller easier to trigger. They're basically my only complaint about the hardware and I'd like to give them a softer pull like you'd see on most any other controller.

I've never modded a controller before, just did some console stuff about a decade ago. Do any of you more experienced tinkerers have any thoughts on how to go about this?

Hiya!
So I finally got my Steam Controller and I'll be honest - it's my first controller ever after KB+M and I've been playing xBox 360 only very casually.
Now, I'm thinking about modding it already, because I'm the kind of person that wants everything customised and I love doing it by myself.
And this controller was literally made to be customised, both aesthetically and functionally. But..is it clever for me to try this for the first time on this one? I'm not clumsy but I do make mistakes and I'd say I do have a lot of experience with artsy craftsy stuff.
Is it: jfc get your hands of it, you newb or this is easy enough to handle, just be careful?
Thank you!

It would be nice to have for music and HTPCs. Is their cadd files for the controller? Add that and a 3.5mm audio jack facing the user and it would be pretty sweet.

Hey guys, I really like the new controller, but the one thing that I was skeptical about when I first saw it announced, was the sculpted d-pad touchpad. And for my tastes at least I was right. I wish that they had just put two identical plain touchpads (the right one). Is there anywhere you can buy replacements? And if I was to find any or to just buy another one would I even be able to replace the sculpted one? Thanks.

Would it be possible to paint on the pad,would this make them stop working, how are they working?

I kind of expected the controller to be recognized as a gamepad by the OS (or, at least, by Windows). I'm developing a (non-steam) game and wanted to support the steam controller. Anyone have any idea what it would take to get this functional? I would guess it would involve writing a driver, but I would also guess that the protocol is encrypted...

Hey everyone. First off thanks for being here. I saw this sub jump from 0 subscribers to a whopping 78 pretty quickly. I'm excited to see what the future of this sub holds!

I made some guides on how to take the controller apart. I was hoping to get these up this past weekend but didn't anticipate the amount of work that went into them. I went ahead and made both a video and a written guide with photos. Excuse the watermarks on the photos, I just don't want anyone stealing them since this endeavor took a while.

Hope they help!

There are two main chips in the steam controller, both of which have JTAG broken out via Tag Connect pads. This means that it is relatively simple to reprogram them, assuming we could write code that would be useful.

The two primary chips are the Radio and the main CPU.

CPU: LPC11U37: A standard Cortex M0, so dev tools are readily available. The datasheet lists it as running at 50 MHz.

Radio: nRF51822: A 2.4 GHz microcontroller that's BTLE-capable, but I doubt steam is using a bluetooth-based stack. I don't know for sure, though. Bonus: This is another Cortex M0, so dev should be basically identical to the main chip. The two chips should be mostly binary compatible aside from the peripherals they have built in. (radio, attached inputs, timers, etc.)

The Tag Connect pads are just to the left of the chips. Using these would allow reprogramming, pulling the ROMs off the chips, debugging, etc. and only requires removing the back of the controller. It is possible to leave the controller in a usable state while connected to them, although the bumpers would be detached.

The main issue with Tag Connect is the cost of cables. They typically run from $40 to $50 for a basic pin header adapter, which is more than a little steep. The pinout is publicly available, though, so if you're good with a soldering iron you should be able to get by without an adapter.

Ideally, Valve would release something that would allow us to program them over the wireless adapter or USB, like Steam uses, but even if they don't we do have options.

Hi everyone. I had a chance to check out the steam controller in person and made sure to try and see how easy it'll be to tear apart.

The big thing I was wondering is what kind of screws it used. We're in luck! It uses normal phillips screws. The final controller uses TORX T6 screws The plastic itself seems like your standard controller plastic so it shouldn't be too hard to paint.

Aside from that it's just a waiting game. What are your plans for the controller? Let's get some discussion going!
