Cat Woodmansee didn't want to commute by car or train, but the 50-year-old Silicon Valley software engineer wasn't up to pedaling his bicycle 60 miles a day either. So, using a kit, he added an electric-assist motor and battery pack to his Electra Cruiser 7D, a standard bike.
This is the third video in our series of maker profiles shot as part of the Red Bull Creation competition. Here, you'll meet the puckish tinkerers behind Virginia-based North Street Labs, who favor the type of project that "makes you laugh, makes you scared, or make you laugh at the person who's scared," to quote one member. They've built everything from a motorized hammock to a game that replicates the g-forces of a Top Fuel Dragster. Warning: Dizzying footage ahead.
It's the simplest planner available. Users type plain-language commands into Coolendar—no need for precise syntax—hashtagging keywords to organize similar tasks. For example, "Monday, 5 p.m., don't forget to pick up the #dry-cleaning." Coolendar automatically slots these into a to-do list and will send Gmail and Google Talk reminders. The free site syncs with other calendars and has an app for smartphones.
Most modern medicines are carefully synthesized organic molecules so potent that each pill contains only a few milligrams of the active ingredient. Pepto-Bismol is a fascinating exception, both because its active ingredient is bismuth, a heavy metal commonly used in shotgun pellets, and because there is a lot of it in each dose.

Richard Hamel was watching the 2010 animated film How to Train Your Dragon with his grandchildren when he noticed something odd about the tails of the flying beasts. Hamel, a longtime radio-control plane builder, realized that those appendages resembled an unconventional aircraft design feature known as an inverted V-tail. In lieu of a vertical stabilizer and horizontal rudder, some aircraft rely on two fins arranged in a V shape.
Animals use electricity to move, and so electricity can be used to make them move, as the scientists at Backyard Brains show in a neat DIY experiment that can be done with a cockroach's leg. For a larger scale version, they connected the device to a squid, which produce pigmented cells called chromatophores to reflect light. By using an iPod blasting Cypress Hill's "Insane in the Membrane" as the stimulant, they discovered a lovely, abstract look at the process.
Preparing for a newborn baby is a lot of work, from buying the bassinet to arranging the diapers. And soldering apart the Wiimote, installing the crib lasers and turning on the camera.
A new Hungarian dad, concerned about monitoring his baby’s breathing, did what any modder would do: He built a baby-breathing-tracker. His name is Gjoci and here are his plans.
