Xtal insulation

Polystyrene added around the xtal. This is of course an imperfect solution as the thermo-couple is in contact with the diecast box and will thus be not only reading the case temp but will be radiating some of that heat inside the polystyrene cube.






Tests underway now with this mod and bead jacket between inner and outer box. Ons at 10 min intervals.

Graphs and stats later.
