well its not 100% solved bit of a clumsy solution and not quite what was originally set out to be accomplished.
Biscuit looked at the folding fob quite closely and we talked about it, what he says is accurate, its not going to be ecanomical to manufacture one, the only way would be fitting the existing one into a aftermarket flip case which is difficult. I might make a folding one for my own use but i doubt i'll ever get the time to put it down as a project so I guess i'll never get the chance
thats the issue it cant be fitted in to an aftermarket one as the buttons don't fit the holes. and the circuit doesnt fit the case, even with major surgery to the PCB. the only fix is a custom designed and built casing. mucho dollars
as for the mirror fix, not really thats a back yard bodge job, the aim was to build a standalone Pic controller that would do multiple functions like auto dip on reversing, out fold on egnition off, open on key fob etc.
