ThinBot -- Work in progress 2-9-2012

Small amounts of progress. I've begun machining the ports into the box that will hold the Arduino Mega 2560 controller and touchscreen (photos of that when its done).

I also did assembled and leak-tested the chiller/nozzle. Alas, the compression surfaces around the O-rings were too small to seal properly and it dripped, so I had to go to the alternate plan (the original plan, actually; the o-rings were a long shot) of using silicone aquarium sealant.

Bottom of chiller/nozzle, after sealing While the o-rings I used for the test assembly looked much neater, they did not seal well enough to keep the tank from dripping. The answer: lots of silicone aquarium sealant (safe for fish and people once it cures!) This doesn't look as tidy, but it should be watertight.
