Custom parts and enclosures

Portlet Enclosure
If you don't want to purchase and injection molded case, here are the STL files which can be 3D printed for the case enclosure
Bottom enclosure
The bottom half of the Portlet Enclosure in case you would like to 3D print it yourself
Top enclosure
The top half of the Portlet Enclosure for those who want to 3D print it


Eagle Files for Linkit Controller board
These files were created in Eagle CAD
Gerber Files for Linkit Controller Board
Gerber files for ordering the board. I would recommend using the provided Eagle files to generate these using whatever settings you are familiar with though.
Power Board Eagle files
These are the Eagle CAD files for creating the power board of the Portlet
Gerber Files for Power Board
These are the Gerber files. I would recommend creating your own Gerbers from the Eagle files to make sure the settings are correct for your board manufacturer
Assembly instructions for Linkit Portlet Controller board
Suggested steps and pictures for assembling the Linkit Portlet Controller board
Assembly instructions for Portlet Power board
These instructions are for assembling the Arduino version of the Portlet but the first section covers assembling the Power Board which is the same as for the Linkit version


Project codes for Portlet
Here is a collection of code sets created in the Arduino IDE to control the Portlet for various projects such as making your own yoghurt, brewing beer, a safety device for your soldering iron, etc.
Testing Code
This is my go-to code for making sure all the wiring and functionality in the Portlet is correct

Got frustrated not being able to find exactly what I wanted so started building it myself
