17-Year-Old Creates a 3D-Printed Robotic Prosthetic Arm for $250

Combining a Nintendo Power Glove with 3D-printed parts, 17-year-old Easton LaChappelle has designed an incredible robotic prosthetic arm. Made from LEGO bricks, fishing wire, and surgical tubing, LaChapelle’s robotic arm earned him 3rd place in the Colorado Science Fair of 2011 – which inspired him to go even further with the 3D-printed design.

At the Science Fair, LaChapelle encountered an entrant who wore an $80,000 prosthetic arm that would need replacing as she grew. Inspired and intrigued, he decided to take his homemade robotic arm, which could only grip a soda can, to the next level. His new goal was to create a high-tech prosthetic arm that was not only highly functional, but also affordable.

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

5 Introductory Tools to Programming

Have you been toying with the idea of learning how to program but don’t know how to get started?  Check out these introductory tools to help you begin to think like a programmer.  Figure out how a computer works, instruct computers to performs tasks, create your first game, and more. 

ScratchOne of the easiest ways to get started with programming is to remix someone else’s already existing program. Remix a project using this free programming language called Scratch. You can build games, animations, music videos, and more.

Minecraft: Use blocks to build just about anything you can imagine in a virtual world. Discover engineering concepts, architecture, mathematics, as well as critical thinking skills and teamwork.

Develop a Game: Get started on building out the code, artwork, and music for a video game. These tools will help you build an interactive experience.

Remix a Website: Never seen the insides of a website? Use Hackasaurus to hack your favorite website to have it look and do whatever you want.

Run a Node.js Server: With Node.js, you can mimic the back and forth request/response your browser sends to servers when you visit a website. Set up your first development environment.

LEGO Robot Breaks Rubik’s Cube World Record, Looks Badass Doing It

This fancy machine just broke the world record for solving a Rubik’s cube. While pathetic humans can take minutes to get the job done, the CUBESTORMER 3 takes just 3.25 seconds.P

What I like about the CUBESTORMER 3 isn’t just the name (you’d say it in ALL CAPS in your mind even if it wasn’t already in ALL CAPS). It’s the look. Most functional robots tend to look spindly, valuing practicality over appearance. The CUBESTORMER 3 instead looks like something that would roll off the production line at Skynet.

The DIY Team spent this past weekend at the Berkeley Art Museum hacking sounds using MaKey MaKeys and Quartz Composer. Kids used construction paper and tin foil to create their own one of a kind musical pad/keyboard and one kid even managed to create a track using his face. Make your own weird sounds and become a Hardware Hacker.
