Hi Luka,

I will practice to use a optoisolator and a separate power for peltier. And I have a issue of peltier placement, does the peltier reside inside the case or outside the case? If the peltier is outside the case, then the cooling if much better, as it has larger heat dissipation area, but the cold finger copper is more long, which brings bad for colding.

Thanks!
