HacKIDemia and SparkFun help launch maker hubs in Africa

January 14, 2014

HacKidemia is a global organization that runs hands-on STEM workshops for kids in more than 25 countries around the world with 8000 children and 400 mentors. They were asked to bring the project to Africa and launched an indiegogo campaign two months ago: http://www.indiegogo.com/projects/afrimakers. The main intention is to enable African makers -- kids in particular -- to use making and prototyping for solving local challenges like access to clean water, energy and information. SparkFun has donated the materials for 7 maker boxes - enough to support the initial campaign goal to equip each of the 7 hubs with a set of Arduino's, sensors, books, and tools.

Guest Blog: Circumventing Science Lab Budget Cuts with Open-Source Hardware

January 23, 2015

High-­school science teachers can radically reduce the cost of building up science labs while giving students opportunities to engage in genuine design processes by introducing them to open­-source hardware. A vast collection of free and pre­-designed low-­cost scientific tools are available, many of which can be printed on a open­-source 3­D printer, including the printer itself. Not only can students benefit from access to research grade equipment, there are ample opportunities for students to build on, improve, and customize scientific tools as part of their curriculum. In this way the number and value of the open­-source hardware designs can expand with student effort, enabling a powerful motivating factor for science education.

Useful Strategies for Makers: Part 1

July 3, 2014

As a middle school technology educator who has a Fab Lab for a classroom, I spend a lot of time thinking about useful tips, tricks, and strategies for young makers.

MakerCamp: Berlin Recap

September 22, 2014

In the end they came away with a global community of support for prototypes that can be kick-started into real life projects. As SparkFun was a partner in the camp, we wanted to showcase some of the awesome people and projects from the camp last month.

Makerspaces: Tool-informed-values or Value-informed-tools?

September 16, 2014

We’ve probably used the word “maker” more times in the last year than we have in the last ten years. It’s pretty evident that making is blowing up. Makerspaces have made their way into blogs on education, hackerspaces are being featured in The New York Times, and a White House Maker Faire was held in lieu of the annual White House Science Fair this year. I think it’s fair to say making is so hot right now.
