Subject: Re: button?
From: Minuk Choi (Choi.Minuk_at_verizon.net)

I don't think much skill(I have none myself) is needed for an immediate "remedy", but I figure, since the only feasible option seems to be, to solder wires and relocate the buttons, might as well see if an interface of some sort can be standardized... for future expansion.

The layout of the buttons... is similar, but not exactly beneath each button of the layout. The F1, F2, and F3 keys, for example, are not on the same line(F1 is a little higher, I believe). There is always the solution of just cutting out the layout part of the top lid... and then you can directly press the buttons themselves... although that leaves the Archos vulnerable.

  Great idea, I "feel" the F3 button or my fmr will die soon...
  I'm interested, but skilless I'm afraid :)

    Objet : button?

    hey gang,

        In the Archos FMR, I'm trying to start a face mod(kudos to those who remember that I was the one who had a problem 'cause a button broke off), and I have a question.

        If you've seen the buttons on the circuit board, they look like the following

    x1 x2
        O
    x3 x4

    where "O" is the button itself, and x1, x2, x3, and x4 indicate soldered points.

        Now, from trial and error, it seems like x1 + x4 or x2 + x3 forms the connection(i.e. button has been depressed). The thing is... is there a reason that there are 4 points? Seems like 2 diagonal points is sufficient(it works for power button, arrow buttons), but is there a reason why it's four points?

        So far, there is no proposed schematic or anything for the face mod, but my objective is to

        a) provide an "interface" by providing wires which will override the buttons that are soldered on

        b) option a) would allow for a different physical layout of the keys
        
        c) option a) would allow for different button mechanisms(touchpad like buttons on iPod-although this smells like proprietary hardware which will be expensive to acquire)

        The reason for this is because I find the button mechanism(a plastic button with an extension to reach the button on the circuit board) to be inefficent, as my F2 plastic button has snapped off, and I have been unable to glue it back on(it broke off again).

    Feedbacks and suggestions would be appreciated.

    -Mark
