An assortment of products using Zigbee.

My favorite find at this booth is this light switch: it harvests enough energy from the motion of the switch to send the signal to the receiver with no internal battery whatsoever!

I got to try the 3Doodler! It feels like a Squiggle Wiggle Writer and Bendaroos put together. It has a few uses like adding analog looking ornaments to your 3D prints or making a thin spoke on a bike that the printer would need an annoying amount of support material for. Honestly, I don’t think it’s very practical but I really like it–maybe it’s just fun to feel like a kid again.
