Okay, all good to know.  Thanks. 

[CNC custom box mod]

Hello, I'm new here.  While waiting for some material last week I had some time to play around, found the 3d model of the DNA 200 reference assembly and machined it aside from a few drilled holes and the USB hole.   Now I'm considering offering a custom box mod with some fancy penblank acrylic inlays and engraving, after a quick jaunt in a vibratory tumbler with some polishing media to hide the gross tool marks, of course.

So I guess my question is, is it a supported process to attach a separate button to the board for firing the device, or is the box mod manufacturer expected to mechanically press the fire button (and others) ?

Is it possible to power it with rechargeable batteries instead of the battery packs?  What about non-rechargeable batteries like AA?  Any other words of wisdom of encouragement?
