A weather station is worth nothing without proper mechanical parts... Therefore, I decided to learn how to use FreeCAD. For this first prototype I ended up with four separate parts:
- Main enclosure (contains the main PCB and solar cell)
- Arm for connection to middle rod
- Connection piece between middle rod and computer fan part
- Anemometer for wind speed detection and energy
For the middle rod, I intend to use a metal pipe from an old IKEA bed I had laying arond. That could be printed as well or bought somewhere (the outer diameter is 10 mm and inner about 9 mm).
I took special care to make the parts printable (see future post on how successful I was).
