July 23 Work Party: Lantern Wiring

Our first work party is coming this Saturday, starting at 2pm. The goal for the day is to repair and rewire the lanterns so that they're ready to hang up in the garden. If you have any of the following items, please bring them with you:

1. Extra ethernet cables (especially long ones we can put in the final assembly)
2. Power drill (and other small tools you have handy)
3. Tarp (to catch sawdust)

Last year, we used molex connectors to attach our LEDs to long-run cables, but we found that these tend to break, especially because they get pulled around outside the lanterns. This year, we're switching over to ethernet jacks built into the lantern surface, and we're going to control the whole project with a Lightuino. This is a micro-controller based on the Arduino and specialized for large numbers of LEDs. We owe a lot of thanks to the designer, Andrew Stone, who rushed to complete an ethernet converter that would interface with our project. We're also going to be adding an ultraviolet LED to each lantern. We plan to use these to light up UV-reactive plants in the garden underneath.
