das keyboard model s - left windows key
« on: Mon, 18 January 2010, 17:17:48 »
so i got the das keyboard model is without realizing that the new "fn" key doesn't actually send a scan code to the computer and thus can not be remapped or used for anything. why they chose to replace the left windows key instead of the menu key or just adding another key to the left of ctrl is beyond me.

so i fixed it by soldering two jumpers from the fn key to the right windows key.  then i put my key caps on (mac) and now i have two option keys.

this is the first thing i've ever soldered.

Did you cut any tracks? If not you may get some unusual side-effects, like broken NKRO. At the very least you need to check you can type all letters in upper case using the shift keys, and that common control combinations work (cut, copy, paste.)

On the bright side, I doubt you did any permanent damage. If all works properly, then well done!

Does this mean the FCN key no longer handles the multimedia controls?  Or does it work fine.  And did you see any other issues using it with a Mac - multimedia keys all work ? The STOP key reportedly doesn't work although this is no big deal, they really should have made that FCN key a toggle option.

Maybe a DIP switch is in order? :brick:


the fn key no longer works as a fn key for some reason. i think it may have to do with the option key also being pressed. i ended up using keyboard maestro to bind F1-F12 as their media keys so i don't even have to press the fn key to adjust volume and stuff since one never really uses F1-F12 in OS X anyway. it all works fine in windows as long as you don't use the media keys.

i dunno what a cut track is... but the NKRO is broken anyway because i'm using USB, right? i really don't know much about keyboards. this is my first clicky keyboard and my brother told me to post my mod on here. ;)

all the upper case letters work and cut copy and paste work as well since those are cmd x c and v.

since the fn key doesnt send a scan code to the computer anyway, the only thing the computer sees when i press the fn key is that i'm hitting the right option key, so it doesnt break anything.

USB doesn't break NKRO, the HID protocol just limits the amount of keys accepted to 6.  Over USB,  you should still get 6 keys pressed for all key combinations.

hey the soldering still looks cleaner than an m10 straight from the factory

if everything is working right you should still be able to get 6 (or did I hear rumor of 12?) on the rollover test at rollover.geekhack.org.

I didn't notice that earlier, but you're right, that is a pretty nice solder job.  Much better than me.  I drink too much caffeine.

i think if i took a closer picture you'd change your mind. i wasnt sure what to do, my plan was to heat up the existing solder and stick the new wires into it, but for some reason the existing solder wouldnt melt no matter what i did, it just got really hot and made the traces all really hot. i ended up just putting some new solder on top of the existing stuff.

Damn those save the Earth people. I never saw the problem with normal solder that worked. Surely by making lead solder we were taking lead OUT of the ecosystem! Or do they think we're using alchemy to magic the lead out of thin air?:panda:

Someone else has already tested the 6-key functionality. Appears to work fine.

I think the point of asking that question was if the mod screws up the matrix, thus breaking the 6-key functionality.

Multimedia STOP doesn't work in OSX if that is a big deal to anybody.  Das should have made the right Windows key FCN.


yeah stop didnt work and neither did the sleep button. but its all good because i got keyboard maestro to turn the F1-F12 keys into their respective multimedia keys

it came to me in a dream that this still is not quite a solution because Super_L and Super_R are different scancodes

i'm not sure i buy that the ROHS solder is a net benefit to the environment, because that's what is widely acknowledged as causing the outrageous Xbox failure rate. meaning we've traded the possibility of lead contamination for the very real massive increase in manufacturing more consoles and shipping those around to people when the solder fails.

and it can't just be Xboxes and Scorpius M10s failing.

in order to register a super_l scancode, wouldn't i have to replace the whole keyboard controller? certainly the controller doesn't support any kind of super_l scancode...

one's on the left, one's on the right. whether you use them differently depends on how your stuff is configured. but in general, much like ctrl and alt, they send different scancodes but have the same meaning.

the only place i can think of where it matters which one i am using is virtualbox, where i have the right one set as the host key and the left one does not produce the desired effect.

I signed up to this forum especially to say THANK YOU to the mod...
I only ever use 1 Windows Key command, and thats Win+D but it was soo annoying that it didn't work just too bad I can't get the Fn key to the other side, as that would still be useful to use.

It helps just to put some more solder on top of the old solder then you can usually remove it with a vacuum pump...

You wont notice anything until it suddenly collapses, a heat bridge can help.
