Last weekend : physical prototyping

A project log for SentriFarm

Solving a key farming problem: is it safe to harvest / spray / sow today? (+experiments with 'big' data in agriculture)

In the background work has been progressing on the improved rain gauge.

There are a couple of criteria:

This is the first rought cut, used for sizing enclosures (hint: this is too big), designing the funnel and tipping mechanisms and electronics mounting points so we can start thinking about CAD'ing the design for 3D-printing and/or laser cutting

We also spent some time considering casing options for the sensor nodes. An obvious option is to mount the lot inside a PVC pipe, but another way is just using a sealed jiffy case or variant.

Turns out for the Linux based system we need to think a bit more about how to fit both the compute module and sensor electronics in with the solar panel charging circuits.

Probably didn't help that my junk box seemed to be full of plastic boxes that were either too small or too large... Note, the following image is actually equipped with the Teensy LC we wont from hackaday (thanks!) rather than the Linux node

And of course we took the chance of a sunny winter day to go trapseing in a paddock posing for photos:

We also used plenty of cable ties and drank plenty of coffee :-)
