Happy Buckling Keyboard
« on: Mon, 02 April 2012, 14:54:54 »
This is an IBM Model M keyboard mod as you can see.

[H=3]Membrane switch patching[/H]
Traces patched with copper tape and drew out via lead wires.




copper tape.



[H=3]Nut Bolt Mod[/H]
Of course this mod was needed to access its membrane sheet.
Just used M2 tapping screws and washers without nuts due to my laziness.





[H=3]Case Mod[/H]
Model M covers are probably PBT not ABS. I used CEMEDINE EP001 elastic adhesive to glue together PBT parts. The adhesive becomes very soft bead like rubber after cure time, so not suit for putty and carving.
Looks like more general Cyanoacrylate adhesive also works well with PBT case and you can use baking soda with this glue to putty and fill gap. http://en.wikipedia.org/wiki/Cyanoacrylate#Uses

Top and bottom cover.




USB receptacle and program switch.


Adhesive bead after cure.


Wrong cut made more seams :(




Not finished completely yet... But I don't care about keyboard cosmetic so much.


[H=3]Controller[/H]
Controller board consists of ATmega32U4 and only some other a few components. Its firmware shares most part of codes with my other keyboard converter or mod so it has features like multi-layer keymapping, media/system control key and mousekey.


Using this wiring method 0.8mm pitch TQFP44 package was wired with 0.3mm UEW on strip board. This was my first try and took very long time and resulted in ugly soldering.




Filed package mold a little because a pin was broken away.

Very nice, I definitely did a double take. Are you going to paint the case?

Thanks.
Added pics and some text in article page.

Painting will be needed to remove seams nicely but I don't care them so much and like original color. So I'm not sure I want to paint.

I cut and pasted membrane sheets and patched some trace lines with copper tape.

I had to look twice to see what it really was!
"Because keyboards are accessories to PC makers, they focus on minimizing the manufacturing costs. But thatís incorrect. Itís in HHKBís slogan, but when Americaís 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 currently can't get this thing out of my head... :)

I wonder, if it is not a mod, what are those little silver things on the plastic barrel that one could see where the ctrl caps are removed? For me it looks like a little screw from a boltmod...
Or was it originally designed with another layout and was later modified to have an ansi layout?

Hi hasu, I hate to necro bump this thread but I am interested in the wiring for this project. May I ask what components you used for the microcontroller and if you have a schematic to reference? I'd like to try my hand at this same project and forgo a teensy as you have. Thanks for your help!

Microcontroller is ATMega32u4 I don't have schematic but you can find matrix of its membrane sheets in code.

They are standard values you can find inTeensy circuit or MCU datasheet. Crystal is 16MHz. I think you can use Teensy or Pro Micro instead of bare MCU.

If you need schematic I'll draw it for you when you really need.
But I need to know how you are serious for this mod befor doing that. First show me your cut down barrel plate and membranes :D
