LEGO’s revolutionary robotic and microcontroller education kit Lego Mindstorms NXT, allows kids to do their first experiments with moving robots by controlling 3 servos and a collection of useful sensors. The kit includes a light sensor, noise sensor, a mechanic bumper and best of all an ultrasonic distance sensor, that works like a charm. You can find my own design for a Lego NTX controlled telepresence robot here.
I recently found out that LEGO published a new education kit for renewable energy that sounds really interesting for teaching kids how wind turbines and solar panels work. The LEGO Renewable Energy Education kit includes a solar panel, turbine blades, a motor/generator, LED lights, an extension wire, a LEGO Energy Meter and full-colour building instructions for six real-life LEGO models to build.
As an additional feature owners of the LEGO Mindstorms NXT kit are able to add the components of the Renewable Energy kit as sort of sensors and data loggers. Connected to the Mindstorms NXT brick, the energy meter works as a sensor and can be used for both programming and data logging.
I just released a tiny and quite useful Android app that is able to open a HTTP server socket on your Android device, in order to serve you a simple HTML5 page that shows the actual smartphone camera output. This is a really simple possibility to get the camera output of your smartphone where ever you can open a browser. If you register a dyn dns name for your smartphones IP you can even refer to your smartphones camera worldwide. I wrote this tiny app in order to get the camera image of an old Android device that is sitting on top of my NXT Lego Mindstorms mobile robot! The HTML5Cam Android app is completely free, so try it for yourself from here.
