I know there is a bluetooth mod for the HHKB made by hasu. As geekhack has lost the article in the wiki, I can't see if it feasible.
Can anyone shed any light on the mod?

Have you tried hitting him up on IRC?
I noticed you are both idling on #deskthority. Perhaps he kept his own notes?

I too, would love to have a bluetooth modded HHKB!

Unfortunately I have no copy of the article in hand. I hope geekhack wiki pages will get back.

You can find circuit diagram and some info on repository.

This mod is very immature and ad hoc and depends heavily on Bluegiga iWRAP4 beta firmware.
To do the mod yourself you will need to read my messy code and Bluegiga's datasheet and application note.

I subscribed this thread now. If you need help post here.

I'm currently working with hasu's code to do a bluetooth mod for my Kinesis contoured keyboard. Right now, I'm just trying to get the USB portion working (I think I have the code modified correctly, I just need to wire up my matrix breakout boards). The next step is getting the bluetooth working. After that, I hope to update hasu's code to work with the official iWRAP 5 firmware and improve power consumption (code comments imply that it isn't great right now). If I can get that all sorted out (or at least the basic bluetooth part) I am considering making my own teensy-like dev board with integrated bluetooth module and perhaps integrated Li-Po charger as well.

Hasu: I might be bugging you more as I get to the bluetooth stage of my mod, especially now that I know you are on IRC

Nice. Looking forward.
I believe iWRAP5 has better support for HID and stability.

HHKB switches requires 5V other than 3.3V while Kinesis will work at only 3.3V without problem.
This requirement of HHKB is very disadvantage in terms of power consumption. I have to say HHKB is not best for bluetooth mod. I would use cherry switch board for my next bluetooth mod, if any.

So whats going on here, have you done som emagic and found out how to make a BT HHKB2 ?

Looks like there is a ready made piece of kit to do this!

Could also be well behaved with a Topre capacitative board's power draw. All right!
