We had a wonderful time building bats with LED eyes that glowed on and off. The kids worked on their kits with us and learned about wiring up LEDs, batteries, soldering connections, and doing a little programming. Thank yous to Revolution 9 in Fairfax for hosting the workshop in their space and thank yous to my crew Maya, Max, Nick and Carol.
