2014-06-23 (M) Sous Vide Oven

I can't think of a project which has gone much smoother than this one. Construction went well and the finished product looks nicely built and seems functional. Despite being a simple device the versatility is impressive.

While talking with a friend it was pointed out that the low wattage of the slow cooker may be partially responsible for the insufficient cooking temperature of the oven. A rice cooker may be a better solution since they are made with the expressed intention of boiling water.

Enough background.

The construction of the sous vide controller was finished on 2014-06-22 (Su) despite some necessary troubleshooting and documentation for others to be able to duplicate the results. The circuit schematic was sketched on the iPad but does not include a calibrating resistor. A 1:1 PDF was made to show the size, shape, and drilling locations for the temperature controller hole. A text is being written in the style Instructables.com but the web page will be made first, unlike the tennis ball launcher, to give a cleaner result. The document, which contains almost entirely new text, has 2 600 words. When this project started, ideas for other uses for the controller were written down as well as easy-to-find alternatives to some of the trickier parts used in the project.
