I invested some 7 hours so far getting to grips with Android Studio and layouts and should be able to post some real mock-ups within the next couple of weekends. I also had another go at Fritzing and it looks manageable enough.

As far as the Jsoknit project goes, the more perspective I get on it, the more pollution I see. The solution I envisage is to move everything that does not pertain directly to coding Jsoknit to other hackaday.io projects, i.e. move thermocouple building to another project page and so forth. In the end, it should be just about defining the Jsoknit interface for a given embedded device. The Android code should go straight to Github. Anyway, onwards and upwards while I am in the realm of the living.
