A project log for Vinduino, a wine grower's water saving project

A friend grape grower uses my Vinduino soil moisture meter in his vineyard now, so I needed to make another .
The electronics assembly is the easy part, mechanical finishing of the enclosure is a job out of my comfort zone.

The enclosure I chose for this project is the VM-series from Polycase. They also offer an optional protective rubber boot, that gives additional ruggedness if you have a need for that.

Back to the assembly. I used paint for a "confidence " stamp on the side where the cut out for the display window needs to be. I use a caliper to scratch lines for the accurate dimensions . For the window I use Lexan acrylic, which does not shatter and -according to the manufacturer - is 250 times stronger than glass. All properties that are highly desirable for farm use.

See below photo collage for assembly steps.

And here is the finished result!
