Sun Switch simple sun tracking electronic device

Step 4 Assembly of the Sensor Housing

Insert both sets of LEDs in the housing then insulate the leads with tubing or tape. Make sure you know the positive and negative leads of both sets of LEDs. Cut and cement a shadow plate between the east and west LED sets. Chamfer the edge of the plate and mount it parallel to the last row of the west LEDs.

I'm having trouble picturing how this works with the rays of the sun. Can you explain why the plate is mounted parallel to the last row of the west LEDs? Thanks, Tristan

basically you need to think in reverse. The sensor LEDs drive the motors when exposed directly to the sun rays. Since the sun moves accross the sky from east to west a shadow will creep across the sensor in the opposite direction. As the shadow receeds the first row of west LEDs are exposed to the sun rays causing a west rotation of the tracking device therefore casting a shadow over the LEDs and the process repeats... you can check out videos on youtube or visit www.greenwatts.info for a better understanding of how this works...
