Title: HHKB style Mod
Post by: hasu on Mon, 04 October 2010, 10:03:50: This is a HHKB style compact keyboard with keymap layers and mouse keys.

The original keyboard is an old Macway TP-999KB-E which has
Mac ADB interface and black simplified ALPS(Fukka or Forward).

I cut function keys and tenkey part out from this keyboard.
I applied RO-59(Smooth Aid) to switch stems and removed leaf springs from some switches for lighter feel.

This use PJRC Teensy as keyboard controler and firmware based on PJRC
example codes. The firmware is available from:
http://github.com/tmk/tmk_keyboard

Mouse keys is not comfortable, but able to do the job without mouse. It is better
than nothing. I prefer a TrackPoint, but it is deficult to install it in an end product keyboard.
UPDATE(2010/01/03): Mouse keys work nice for me now and I'm no longer as eager for TrackPoint as I was.

Post by: ironman31 on Mon, 04 October 2010, 10:52:43: Nice looking keyboard. Was this just a one time deal, or were you hoping to try and sell these?

I figure the community is craving something like this after the mini Guru failed to follow through
Title: HHKB style Mod
Post by: itlnstln on Mon, 04 October 2010, 11:01:52: Do that with a brown Cherry keyboard, and you will have one sold to me for sure.

(I'll assume you swapped the JK keys as a kind of watermark for the photo. :smile:)

Post by: Findecanor on Mon, 04 October 2010, 15:45:47: Nice mod! The layout is not my cup of tea, but I applaud people who are daring enough to start a mod like this and follow it through all the way.

Ripster: Nice pic! Notice that all of the keyboards in the picture have Cherry switches of one type or another ...

Post by: hasu on Mon, 04 October 2010, 19:35:51: Thanks for responses, all.

ironman31: I would buy a mini Guru.if it was available. I hope that a compact KB with TrackPoint and Topre/CHERRY switch will be availble from some corp.

kriminal: Some photos of inside is attached at bottom of the article. It is a dirty work of cut and paste.
Title: Added TrackPoint(PS/2) support to firmware
Post by: hasu on Mon, 03 January 2011, 05:24:17: I added PS/2 mouse support to my firmware.
And TrackPoint unit used in Thinkad keyboard is just a 3buttonsPS/2 mouse.

This means it is ready to install the unit into my keyboard,
but I found my keyboard doesn't have enough room for the unit. :(
(The TrackPoint is working well outside the keyboard.)

If you are interested in PS/2 mouse or TrackPoint support, see ps2.c and ps2_mouse.c.
(Trackpoint specific enhanced PS/2 commands are not supported so far.)

I think most pointing stick units are.

Sticks from scissor keyboards are too short, you need an adapter. If you can't make it yourself, PM me.

I made an adapter from a drink straw and hot glue. like this:
(http://img842.imageshack.us/img842/2141/201101041881.jpg)

But it was too thick to install between three ALPS switches :(
I need a bit thinner post.
I have to read zmurf's TrackPoint mod (http://geekhack.org/showwiki.php?title=Island:11420) again to know how he did.

I am very curious about your adapter option. I'll PM you later.

Post by: j_r on Mon, 03 January 2011, 22:44:43: Superb work! I also appreciate your driver documentation on github; I have been scouring the internet for how one goes about developing such a thing (I have limited experience with programming... entry-level C++ and program specific languages, i.e. Maxscript and Rhinoscript). Thank you, I now have some homework.

Hi, hasu
You really did a super mod!!!

Can you tell me board pinout of this trackpoint unit??
I have one looks like yours....
Title: HHKB style Mod
Post by: hasu on Sat, 02 April 2011, 10:26:25: arieswu,
I don't have this board in hand now, so I'm not sure but it was Type A.
I have seen only two type of Trackpoint board: Type A board is common and B is rare.

And see this thread for pinouts and some pic of TP board.
http://geekhack.org/showthread.php?t=8971

Type A:

Thank you so much

I read the thread and have one another question..

the 4.7k Ω resistor has 1/4w, 1/2w, 1w...which one should I use?
Title: HHKB style Mod
Post by: hasu on Sat, 02 April 2011, 19:39:57: arieswu,
You can use any resistor wattage, even 1/8w is enough.
And the resistor value is not important in most case too, you can choose from 1k-10k ohm.

I saw your 40% keyboard with Trackpoint. Nice mod!
You should post its article on GH :)

Post by: Dox on Mon, 26 September 2011, 20:45:45: Hey hasu, I've just finished adapting your firmware for my doxkb! It was quite a challenge to figure everything out but it all seem to be running smooth now. The mouse keys and the windows volume control is very nice!
I discovered a couple of bouncing switches with your firmware that were not a issue with my last one. any ideas what could cause this?
An other little question, there seem to be quite a bit of delay between when you press a function key and when you can use the function layer. Any way of reducing this delay?
Thanks for sharing this!
Title: HHKB style Mod
Post by: hasu on Mon, 26 September 2011, 21:45:32: Hi Dox, I'm happy hearing this!

Basically mechanical switches need debouncing to cancel chattering, but my firmware has no debouncing code yet. Fortunately I've not experienced bouncing on my keyboard so far :)
You can add debouncing code into matrix.c to solve your bouncing.I will add the code some time soon but I have no testing keyboard for now. I will post it in this thread when finished.

Yes, layer switching has some delay intentionally for some situations, if you don't need it you can reduce it with defining LAYER_ENTER_DELAY to smaller number in layer.c
Title: HHKB style Mod
Post by: Dox on Mon, 26 September 2011, 22:12:05: Thanks, now that I think about it, I can see why you would sometimes need the delay to engage the function layer. I'll play with it and see how it goes.
Title: HHKB style Mod
Post by: hasu on Thu, 29 September 2011, 03:27:14: Dox,

I added debouncing code to my firmware.
http://github.com/tmk/tmk_keyboard/commit/6284b147c23aa32a9e65138b1eb8ee908ece4941

The code locates in macway/matrix.c and you can found setting in macway/config.h like:
#define DEBOUNCE 5
You can use 0 if you don't need.

Plz try it and let met know this cures your problem.

Thanks.

Post by: Dox on Thu, 29 September 2011, 09:35:48: Thanks hasu! This seem to have fix the problem. I'm currently at work on my ergo clear version and the bounce was rare on this one. I'll try it on my cherry blue one tonight as it was bouncing all over the place.
