Just a gallery for now:
Exploded assembly.
The Francis turbine that will be used in the device. The blades are relatively thick so that they are not weak due to the small size (blades are just over 1mm thick and turbine diameter is 16mm)
Device with bracket mount in case the device is too large/heavy for mounting onto a tap or just for when the user prefers it this way.
Can also be mounted horizontally.
Using two M4 wall screws.
The hole positions are indented to allow room for the head of the screw between the bracket and the device.
Grips at the ends of the arms of the bracket.
