Tuesday/ cool inventions – Willem's Planet

Check out this nifty little wireless ‘robotic’ printer.

Spring for this DIY air filter by Gus Tate if you live in Beijing or Shanghai .. about $35 vs. an expensive $800 installation. It is equally effective at improving indoor air quality !

Here’s inventor Frank Wang’s easy-as-pie-to-use-out-of-the-box drone, the Phantom 2 Vision +. Buy it on Amazon or at Best Buy for about $1,400. (Be careful where you fly it! Don’t get it shot down!).
