In today's community call, several topics were identified that generated their individual excitement. First, was about littleBits in public spaces. How do you design and accommodate the (random) public to interact with the technical art? What is the best way to ensure the safety of the littleBits? And what the heck would you design? Second, was the use of car batteries to provide many hours of life for a littleBit in operation. I mentioned that in a park bench project, I could get about 30 days from a standing battery for a circuit that was available 24/7. This type of persistence opens the door for so many ideas. Layered on the battery idea is solar charging and how to integrate the three (littleBits-battery-charger) into an affordable design. Lots to work on and create!
