Touchy-Feely Lamp with Arduino Starter Kit Tutorial Video

In his 8th tutorial video, Massiomo Banzi explains how to build a touch sensitive lamp, by using the electronics parts from his Arduino Starter Kit, which is available on RS Components (see my Arduino Starter Kit unboxing article). Banzi also explains how to use libraries within your own Arduino development project, in order to speed up development of Arduino program code. External Arduino libraries are available for many different purposes and since the Arduino community is larger than any other maker and DIY electronics community there are a plenty different libraries available for free.

Help GeoGebra crowd source for the iPad

Remember my recent post on GeoGebra, the innovative and open source mathematics learning software that has attracted a global community of school teachers? GeoGebra is the best interactive software for explaining and teaching mathematic examples. And the best thing is that you can get and distribute GeoGebra for free.

Now the creators of GeoGebra started a Kickstarter pledge for porting this cool piece of software to the iPad platform.

We want to make GeoGebra available for the iPad. An html5 version of the software is already available and partly working on tablets without Java. But this is not enough, we want a real iPad Application. A GeoGebra app free to download for everybody from the Apple AppStore.

The reason why we want to keep the iPad application free is because GeoGebra itself is free and keeping it so we want it to be available for everyone. If we reach the desired 10,000 dollars, we can support the development.

I think the team around GeoGebra really deserves a huge crowd of backers for their enthusiasm to bring maths and MINT topics to children wordwide!



TED: Daphne Koller speaks up for a revolution in online education

Daphne Koller is asking top universities, such as Stanford, to put their courses online for free, but not just as a service, but as a way to research how people learn. She tries to discover how knowledge is processed and absorbed by her audience, through tracking each keystroke, asking comprehension quiz and peer-to-peer forum discussion.

Daphne Koller is bringing courses from top colleges online, free for anyone who wants to take them. Her Website already has an impressive number of online students who follow her courses. Daphne Koller is working as a Stanford professor and founded her startup Coursera for sharing online courses.

She follows the same vision Peter Norvig has already presented before in his amazing TED talk on his experiences with his 100.000 student classroom on modern approaches of artificial intelligence last year.

Arduino Controlled Drawbot

One of the highlights of the Vancouver Mini Maker Faire was Dan Royer’s drawbot kit in action. Dan sells his Drawbot kits online. The kit includes a 3D printed pen holder, 2 stepper motors, a 12V 2A power supply, 2x 3D printed bobbins, an Adafruit Stepper shield. The whole drawing bot is based on an Arduino UNO. The kit requires no soldering or wire cutting, and is perfect for use in a classroom.

Drawbot is even easier to use than any other machine of it’s kind. Choose a picture from your computer and the Java program will prepare it for you in 10 minutes or less. It also understands GCODE, the language used by 3D printers and industrial fabrication machines. You can even take the GCODE and send it to your RepRap or Makerbot.

GeoGebra: Understandable Math for Everybody

Some ideas have the power to change the way we are thinking about everyday technology and knowledge. For me GeoGebra is such an idea which has a really positive effect on how we are teaching basic and advanced mathematics to children and adults. The idea behind GeGebra is to provide a powerful open source software for visualizing mathematic topics in a very intuitive and understandable way. Over the last years hundreds of mathematic teachers worldwide created a GeoGebra community which shares mathematic examples and new ideas for the further development of this genious framework. The team that developed GeoGebra has already won several prices for their incredable work. GeoGebra offers interactive graphics, algebra and spreadsheet and a lot of free learning material from elementary school to university level.
