ThinBot progress

Today I made the nozzle jets for the heat exchanger. The final 2" is bent (electropolished=food-safe) stainless 1/8" OD tubing. This constriction at the end of the line (the rest is all 3/16" ID) should accelerate the ingredients into a set of streams that mix better in the glass.

I also got the glass-detection microswitch wired up and the code now recognizes it properly.

In addition, pigtails permitting two additional pumps have been wired in. The code has already been updated to make use of them if desired.
