I was wondering if anyone figured out what the empty connector on the original controller slot at CN2 was for. Sorry if this was asked before!

If I didn't want to reprogram the firmware on the fc660c but just wanted to add Bluetooth to it. Would it be possible to do by just modifying the existing controller?

I got FC660C the other day and looked into this. I also didn't see any activity on I2C lines to control the digipot so far, as this post says. We don't have to configure the digipot to scan keyboard switches at least.

Not fully tested but I can scan switches now.

I am typing on FC660C finally with my own controller :thumb:
I'll design controller PCB for this and create new thread to share info of my controller later.



To share info with community I traced its PCBs with my trusty fluke and drew nasty diagrams for many hours  but...
today found FCC marking on label of the board and Google led me to this schematic and parts list on FCC site, LOL. To be honest, I didn't know how FCC works, it is very useful, TIL.

This is probably a dumb question, but when you get TMK running is it able to change the LEDs on the 660c? Specifically, I like to swap caps and ctrl with DIP 1 but after you do that if you hit where caps is moved to it doesn't light up the led on the control key despite the fact that the long control already has a led window anyways for some reason.

With my current firmware the LED always indicates Capslock state wherever you remap Capslock to any position. If you write small code in C lang you can control the LED fully to do what you want.

Cool, thanks. The default LEDs on the 660c have got to be my biggest bug-bear with the board, I love it but despite all the things they did right they really made those make almost no sense. Looking forward to the news.

Agreed. The only reason I haven't bought one is that there's no Hasu controller  :)

Is there a chance this controller will be bluetooth? I told myself not to spend a penny more on keyboards but for a bluetooth fc660c I would not hesitate to sin one last time, that **** is endgame.

Hey Hasu,

Look what I found inside when silencing my FC980C!

http://imgur.com/a/UGK68

How similar does this look to you compared to the controller in the FC660C? Maybe an idea for a future project?  :p

Could it even be as simple as creating a controller that goes in-between the USB connection?


I'll be opening up the 980C a little later to convert it to MX, I can take a better look at the other side of the board if you'd like. Looks like there's plenty of space in the case for batteries and things though...

Looks very similar and I guess no big difference from 660C. No plan for this board unless someone is willing to donate me ;-)

It will have same short battery life woe as HHKB does. But it is still possible.

+1 for BT, I don't have a battery in my HHKB; I still find it extremely useful to quickly type out texts on my phone while it's powered by my PC.


As for the FC980C, someone in Tokyo pls help out. I'd gladly lend mine for a few weeks but the shipping from AU to Japan and back might get a little bit pricey...

Bluetooth would be a charm - I usually type with the charger cable in on my HHKB (with 2000mAh) when I'm home/office, and use it on bluetooth when I'm outside. Have got past some days of not charging it, and it still works. As long as the battery life is > 1 day I'm happy with it.
