Quadcopters and the revival of the RC Enthusiast 

Quadcopters are the latest craze in RC technology. One day, these machines may take the place of cargo planes and delivery trucks, eventually flying over your doorstep to drop off DIY patches. The technology is already there, and companies like Amazon, UPS and FedEx are exploring their own autonomous delivery systems. FCC rules and red tape notwithstanding, kids that are adept at flying RC quadcopters today may be the ones designing these delivery systems tomorrow.

There’s been a revival of RC hobbies as the cost of building RC devices has plummeted and the curiosity for quadcopters has surged.  This is one of the many reasons why RCer is the latest skill on DIY.  Aside from the fact that attaching a camera and flying a thing around is really cool, building your own RC focuses on a broad range of skills – from mechanics, to technology, and even artistry.

Although these are rich subjects on their own, when combined, they complement each other superbly. Building an RC car, boat or quadcopter allows you to experiment with complex systems on a small scale, which is a great jumping off point before scaling up to actual cars and helicopters.

The process of building your first remote controlled anything - figuring out it’s mechanics, gears, sanding it down, and the comradery experienced in a flying range are some of the most awesome memories a lot of us cherished as a kid. Now, it’s possible to take that same experience and also take a video 200 feet in the air.

DIY Club Spotlight

Susie, a teacher at an International School based in Indonesia started using DIY in April of last year to plan after-school activities and field trips. Since then, she has used the app as part of her core curriculum - incorporating challenges and projects in her class of 5th and 6th grade students. For more updates on what this club is up to, be sure to check out their portfolio.

Pouring an ice cube using supercooled water:

The temperature of the liquid water is reduced below its freezing point, without becoming a solid. The ice wont form without the presence of a nucleation point (a crystal or impurity around which an ice crystal can begin to grow). However, on contact with another surface, the water instantly freezes. Check out how to make instant ice at home in this video: http://youtu.be/sBFK5-JvBAc
