Race constant LED on
« on: Wed, 05 September 2012, 12:13:10 »
The suckiest thing about KBT Race is that LED resets on restart. This means you have to do Fn key mashing to re-enable the LEDs constantly.

Anyone think this might be modded to make the LED stay on always? By soldering somehow. I have experience with digital circuits but not so much with soldering.
If anyone has a hi res picture of the PCB that would be great.

if you plug it into a powered usb hub it will stay on due to the powered usb hub using a dedicated power source.

make sure the usb hub has a separate ac adapter.

if it were a single key i would say you could just jump it but it requires an fn+key combination, so it's handled by the controller. not that it wouldn't be possible, just harder to do.

domoaligato -- that would work but it would be on ALL the time, and i think Cindori just wants it to come on automatically whenever the computer sends power.

The original Ducky Shine has this problem, but I don't reboot that often so it is not that much of a problem.

But if there is a simple hack that can be done, well ...

"Because keyboards are accessories to PC makers, they focus on minimizing the manufacturing costs. But that’s incorrect. It’s in HHKB’s slogan, but when America’s cowboys were in the middle of a trip and their horse died, they would leave the horse there. But even if they were in the middle of a desert, they would take their saddle with them. The horse was a consumable good, but the saddle was an interface that their bodies had gotten used to. In the same vein, PCs are consumable goods, while keyboards are important interfaces." - Eiiti Wada

I forget if this happens on windows or linux, but when I had it connected to my Mac at work it would turn the LEDs off whenever the mac went to sleep too not just power off :\

well thats how sleep works. every led keyboard will behave the same.

its not the issue that it turns off, its the issue that I need to do hotkey dance with my fingers on every boot to get my preferred lightning mode.

here is hires pics of race boards:





Right click - Show image to get full sized.

That holtek controller is for the keyboard. I wonder what the other thing is. It looks a bit smeared, like someone wiped the text off it....

I´m not too comfortable with circuit boards, but I guess its likely to be that component responsible for the LEDS.

However, the thingies to the lower right also caught my eye. Are they D-elements? (state components) they are labeled Q1 Q2 Q3 Q4...

those are the DIP switches that swap keys around but i dont think that any of them keep the LEDs on.

I guess mac and PC is different - the mac goes to 'sleep' aka the screen turns off and all power to USB seems to be cut, whereas a PC goes to sleep and the screen just turns off.  Standby is a whole 'nother thing.  Would be cool though for the keyboard to have a memory and start back up at the same brightness/LED setting.
