Figure 1: Photographs of the current Lego-based IR beacon. Top left: View of the tetrahedral LED array. By coincidence, the LEDs fit exactly into the Technic bricks' holes, and were fixed from the back with hot glue. Top right: View of the battery holder and power switch, which coincidentally exactly fit a 2x1 Lego brick. The "on" position is marked because the IR LEDs are completely invisible to the naked eye. Bottom center: Full frontal view of the LED array, as it would be seen by the Wiimote's camera. Click on each of the images for a higher-resolution version. |
