 ====== Carport controller ====== ====== Carport controller ======
 I designed a custom wireless ZigBee carport controller, in order to minimize risk of accidentally locking ourselves out of the house. I decided to use the XBEE3 MMT chip, as these are compact, easy to use and receive regular firmware updates from the manufacturer Digi. They also support security features and have AES encrypted communication.  I designed a custom wireless ZigBee carport controller, in order to minimize risk of accidentally locking ourselves out of the house.

 ===== PCB design =====  ===== PCB design ===== 
 +Designing the circuitboard was a fairly straightforward concept. I decided on using micro USB as power connector, as these are easier to solder than USB-C. 
 +
 +Three screw-clamps where added, one as 24V input for carport open/closed readout. The two other screw-clamps are used to connect the pcb in-between switch and carport. Which makes installation easy and neat, without additional external wire-clamps.

 +===== 3D printing =====
 +I 3D printed a small enclosure, in order to cleanly mount the circuitboard to my carport. The enclosure itself is printed using Prusament Galaxy black, the top-lid is printed using fillamentum transparent filament. I also printed the screws in the same transparent filament, as this looks cleaner than metal screws.

 +Print screws always on 0.1 mm layer height, as 0.2 mm lacks the required precision.

 +===== Software =====
 +The software is still a work in progress. I would like to add an carport open/close button on my inwall-display, then convert it all into an Android app. 
 +
 +===== Result =====
 +The module was attached to the carports cover, using the 3D printed screws. I drilled 5 holes through the cover, 2 for the screws and three for all the wires. The green LED looks rather fancy when it's dark, even when only consuming 0.7mA at 3.3V ...
