NEW YORK — A festival of tech enthusiasts, DIYers and crafters is taking over the New York Hall of Science in Queens this weekend.

The fifth annual World Maker Faire in New York will be open Saturday and Sunday (Sept. 20-21). This celebration of innovation, hands-on education, science and technology will feature some of the latest 3D printing and drone technology, science demonstrations and a host of DIY projects.

World Maker Faire describes itself as "the Greatest Show (and Tell) on Earth." The event will include exhibits, discussions on technology and education, and workshops and lessons on topics such as how to build a simple circuit and how to get started in 3D printing.

Here are some of this year's highlights:

-The 3D Printer Village will have tons of 3D printing enthusiasts ready to show off their creations.

-Robot Row will feature small robots designed by individual engineers and small companies.

-The Amateur Astronomers Association will have a suite of telescopes set up for stargazers.

-A drone flying competition will challenge drone pilots to navigate obstacle courses and engage in mock airborne combat.

-All kinds of wearable tech, including air quality sensors and temperature-sensing clothing, will be on display.

-NASA's Niki Werkheiser will discuss the future role of 3D printing in space technology and space exploration.

-Demonstrations of Tesla coils will shoot out "lightning."

So-called "makerspaces" are popping up across the United States where hobbyists, enthusiasts and other "makers" can connect and even launch their own company or products. Makerspacesprovide access to low-cost industrial manufacturing tools and offer classes where makers can learn how to build and market their product. Maker Faire is a celebration of the latest innovations and creative projects to come out of these makerspaces.

"We'll be showing the attendees this year the pioneering spirit, imagination, and achievements of how makers are making the future," Sherry Huss, co-founder of Maker Faire, said in a statement.

This year, there will be about 700 makers and an estimated 85,000 members of the public in attendance. Tickets for the event are available on the Maker Faire website. Weekend passes range from $30 to $60, and one-day passes range from $17.50 to $32.50. Visitors can also buy tickets at the door.
