Assignment: Propose a final project that integrates the range of units covered, answering: What will it do? Who's done what beforehand? What materials and components will be required? Where will they come from? Wow much will it cost? What parts and systems will be made? What processes will be used? What tasks need to be completed? What questions need to be answered? What is the schedule? How will it be evaluated? Projects can be separate or joint, but need to show individual mastery of the range of skills covered. Where possible, you should make rather than buy the parts of your project.
It will have internal channels that will drain moisture away to the outside, instead of the condensation dripping into the bee colony during the winter, as that can kill the bees.
It will incorporate an internal sensor that will display it's readings on an external LCD screen. The sensor in this project is a temperature sensor, but more can be added later, such as a moisture sensor.
The Open source beehives project has done this already with the sensors, the difference with mine is the inclusion of the moisture drainage channels, for winters in cold climates.

Will invariably differ from country to country.
As of june 11 I have one ShopBot session left, to cut internal gutters and locating strips for the main structure. Then it has to be varnished to seal the plywood surface. I have to run wires from the power supply to the sensor pack.
Mon-tue 11-12 june - mill and fit plywood strips.
Tue-wed 12-13 june - run wiring - varnish structure.
Wed-thur 23-24 june - prepare presentation video.
Fri 15 june - presentation.
How much of the process is relevant to the skills and methods learned at the Fab Academy course.
How close to completion the project is at presentation
How neatly the different methods and materials have been integrated.
How closely it resembles/differs from similar projects.
How can it's function be improved upon, once in service?
Is it feasible to add an internal metal plate for controlled moisture condensation?
More sensors will have to be designed and integrated in future, primarily an internal moisture sensor.
