Sound files on the NXT Sound-files on the NXT should be in the .rso format. Use wav2rso.exe to convert .wav files to .rso format. .rso files should be copied to the folder C:\Program Files (x86)\LEGO Software\LEGO MINDSTORMS NXT\engine\Sounds before they can be used in the NXT software. Create a “Sound” block, select “Sound File” at … Continue reading Using sound on the NXT
Monday I give a Littlebits-workshop for students doing a project on “Design for Specific Users”. We are going to practice building small, interactive circuits. Aim is to investigate design possibilities in the idea phase of the design process and quickly try-out different directions for idea’s. Students are encouraged to experiment freely by building circuits, mixing inputs … Continue reading Workshop Idea Generation with LittleBits
By utilizing the Arduino-bit and the Proto-bit, all kinds of electronic circuits and components can be connected to a Littlebits circuit. In this example, we connect an Ultrasonic sensor to the Arduino-bit with the Proto-bit. The distance measured by the Ultrasonic sensor will be displayed on the Number-bit. This example is based on the Bat … Continue reading Build a distance-sensor with LittleBits
Sometimes I get a question from a student or colleague on why we choose Java as our base for the introduction to programming classes. Here are some quick reasons: It is a ‘proven’ language to quickly learn programming It is used as first learned programming language in a lot of other universities and high schools It … Continue reading Why learn programming with Java?
Tomorrow I give a Littlebits-workshop for students following the course “Embodied interaction”. We are going to build small, sensory action-reaction type of circuits which are worn by the participants. Aim is that every participant has an output and an input-circuit on his/her body. While walking around, the circuits may trigger reactions on the other participants output circuits. … Continue reading Embodied interaction with LittleBits
This week my students had to perform a peer-review on each other’s websites. They also had to summarize the review (and their opinion on it) on their Blog. I was very pleased to see a lot of quotes like the one below.
Updated Jun 2016. These are some examples of partial results of the Digital explanation which where presented as a result of the Project ‘Virtual Product Development’ from Industrial Design Engineering: DASH AUGMAX Interface for a Luggage storage service system The ‘bibliotheek’ To Go Peek-a-band Note: unfortunately, most of the sites for this project have already been … Continue reading Project ‘Virtual Product Development’ – sites presented as part of Digital explanation
If you have an RFID reader module attached to your computer (via a USB serial connection) you can read RFID data from a Java application. For instance, you can use the unique id (Card UID) to identify something or someone. You can learn how to build you own RFID reader here. To use serial communication in … Continue reading Add RFID identification to a Java application
The RC522 RFID module is a cheap module which comes with a card and a dongle. You can buy it at our local electronics shop the STORES for € 4,85 (search for ‘rfid’ in the pricelist). Only thing you have to do before you can use it is solder the header. If you are unfamiliar with … Continue reading Build an RFID reader with Arduino and the RC522 RFID module
In this previous article we learned how to build an App with App Inventor and connect it to a Lego Mindstorms NXT. Now we will extend that App to control a Catapult robot. If you have not done so already, first build the Catapult. Now that you are able to connect your phone to the … Continue reading Remote control a catapult with an App build with App Inventor
