The humidor is running :).

Tested in outside temp 22C - inside temp 12C :), when the heatsink is kept above dew point.

Tested also in cold conditions : outside temp 10C inside 20, 25, 30 40C...maintain the temp, but still some issues that can be avoided with the re-setup.(there is protection how much hot air is coming out from the inner heat sink, it was set to 5C, so it wasn't enough to compensate the heat leaking out from the humidor).

There is a few more bugs to clear...work in progress :)...
