One point calibration

Due to tiredness, and the prospect of yet another 11 hour day in the office tomorrow, I was only able to measure one potato. Despite this rather pathetic attempt at calibration, it's a heck of a lot better than it used to be. It felt really good to hold the potato up to the screen and read the right answer back.

First calibration weighings

After much time away from the project, I return armed with some brand new kitchen scales. They will be used to calibrate the system, so in effect these will be the scales that lucky people out there will use to weigh their potatoes.
