Many people try to fly microkites in the breeze from a desk fan.
Almost every single one fails, due to the extremely turbulent nature of the breeze from a fan. It's worse than trying to fly a full-size kite between tall buildings.
This device allows you to fly microkites indoors, and could be seen as a kind of art installation as well.
Step 1: Materials.
The machine started with the motor. It's a microwave motor from Ebay, which is geared down to 4rpm, and has a vertical spindle.
I also used a mains-rated rocker switch, a quarter-inch nut, some flat spade connector thingies, an extension cable (it worked out cheaper than buying cut cable and a plug) and a cheap trinket box to mount it all in. I also used a ten-foot length of thin pine dowel.
I used normal hand and small power tools - drilI (with a selection of wood bits), rotary tool with a sanding bit, wire cutters, pliers, screwdriver and glue gun.
