Here’s a full size hoverboard, kinda bulky but works.
Here’s Zedomax Hoverboard based on earlier article DIY
I got too excited about the DIY I had to make one. So I just hacked out my computer 12V fan
and got my leftover over Pizza Hut paper dish and wala!
The only problem I encountered was that the battery was too heavy, so when I tested w/ a
DC power supply instead, I could get it to hover over my desk about 1mm…
So, maybe next time, I will try 2 fans…
