Do you like to jump rope as part of your exercise routine? Let me introduce you to Tangram Factory’s Smart Rope, a jump rope with 23 LEDs embedded in the middle of the rope that light up in front of you to display your current jump count while you’re jumping, courtesy of the old persistence of vision effect.

More and more contraptions that charge devices or generate power without needing an electrical outlet are hitting the market. Some, like the PULSE Kinetic Jump Rope, are in their prototype stages, while others like the Voltmaker are ready to be shipped off.
