PS/2 keyboard hardware assembly
« on: 2016.February.28. 11:01:52 »
I have an enterprise machine like this:

https://enterpriseforever.com/hardver/az-alom-ep-projekt/msg53212/#msg53212

It is naked like that, it is not assemled to a case and will not be.


And I have a PS/2 keyboard controller solution with an arduino micro board involved:

https://enterpriseforever.com/hardver/hw-keszites-arduino-val/msg41972/#msg41972
https://enterpriseforever.com/hardver/hw-keszites-arduino-val/msg41897/#msg41897
https://www.arduino.cc/en/Main/ArduinoBoardMicro


And now, I would like to assemble the above arduino micro to the above EP motherboard,
but I do not have an idea how to tie, how to fix the arduino to the motherboard.

Also I do not know how to tie/fix a PS/2 socket to the EP motherboard.


So, I have the software on the arduino micro and I know how to wire the arduino to the moderboard and a PS/2 socket to use a PS/2 keyboard with the EP.

But if I do the wiring, then the arduino micro and the PS/2 socket will "fly on the air" on the wires ... :)

So what I asking for is an idea or a technique how I can mechanically/physically tie/fix the arduino micro and a PS/2 socket to the EP motherboard above.


Please do not say "using a rope" ... :)

Maybe, try to use the glue gun?

No, this EP will stay naked. This does not go back to a case.

It is, because of the EnterMice and your planning of other extarnal expansions,
and these have no a casing, and I don't like mixing of a cased EP with uncased PCBs,
because I do not feel that nice enough.

But I like a fully PCB EP, and that can get expansions more easilly like cased ones.

So I plan to use two EPs, a standard non expanded cased one, and the one naked above with many expansions.

That's right, billions of Chinese people can not be wrong :smt043

Use the cover of the PC. Immediately you have a built-in power supply.

Yes, we think of that, but I do not think I will find such a minimalist (sizes, design, no unnessessary USBs and such) PC case what I could like ...

I like the idea of a PCB EP otherwise ...


I just cannot fix my gadgets to it ...

It is therefore only plate of plexiglass.
Or better two. An one underside, second from the top.

Yes, I thought of it, too.
Maybe it could be ... but it is so much tinkering (gadgeteering) ...

Something would be good between this and the glue ... :)





And I just found the solution, pear ! :)

You could make a PCB like the EnterMice itself, just it is for the keyboard,

and that would have connectors like the keyboard fixer has !


I would just push that device to the official keyboard sockets on the motherboard,
and I could throw my keyboard stuff to the bin ...

Problem would be solved ... :)

It can be done.
Still, this does not solve the problem of mounting plates.
On thin keyboard connectors may not withstand.

Unfortunately that was my best idea about the topic ... :(

On the left side of the motherboard are two openings.
In one (on the picture at bottom) you already have the spacer. In the second hole (upper) you would have to add a second.
The third point of support can then be left keyboard connector. The right keyboard connector will connect by the tape.
Perhaps in this way?

Hmmm ... I think I did not get you yet ...

What case do you think about ? My arduino case ? Or your "new keyboard solution" ?

In the arduino case, I would like to use arduino micro board itself, what is a
4.8 cm X 1.77 cm
thingy ... and light, it's almost staying in the air ...

High speed draft :)
One picture as a thousand words.
A chip shape is as the Arduino.

Ahhh ... you think about assembling the arduino micro and the PS/2 socket together to a bigger pcb ...

Hmmm ... maybe .... there are PCB -s like these:
