SunTrack: follow the sun to catch its reflection
IMG_9100.jpg

Here’s a great way to increase the sunlight you bring indoors:

SunTrack

The SunTrack system can reflect the sun in my house and keep the reflection all day. That way it is possible to have a lot of light in my living room witch is facing east.

With a KlikAan remote control (433mhz) it is possible to:

Calibrate the sun postion by relecting the sun back and ajust the shadow.
Move to a point where the reflection should be, and save 3 reflection points.
Select one of the three reflection points and stay there by adjusting the rotors.
Power down: go to the sleep position.

(via hack a day)
