This guide explains how to build the Lego Mindstorms model “Spike”, powered by an Arduino and an EVShield. The original version of the Spike is powered by a Lego NXT. Requirements EVShield, Arduino Uno, Battery holder (+6 AA batteries) Lego Mindstorms kit (can be either NXT or EV3) Introduction To make a sturdy, compact solution … Continue reading Lego: Build Spike with Arduino brain
This guide explains how to build a motor chassis, which can for instance be used for the Lego Mindstorms model “Spike” powered by an EVshield with Arduino Uno. Requirements Lego pieces to connect the parts as displayed: Introduction To make a sturdy, compact solution which allows access to batteries, ports and pins of both the … Continue reading Lego: build Spike motor chassis
This guide explains how to mount an EVshield with Arduino Uno and a battery pack. In this way you can use it as the ‘brain’ of a Lego Mindstorms model. Warning: do not insert batteries in the battery holder until you are ready! (have build a finished model) If connecting the USB cable, first remove … Continue reading Lego: mount EVshield with battery pack
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

To use leJOS you need 32 bits versions of the JDK and the Java Runtime Environment (JRE). Also, sometimes after updates of Java or multiple removals/additions the environment can ‘go bad’. Follow the steps below to test the environment and fix it when necessary. Test Java Windows must be able to find Java programs. Therefore the … Continue reading Checking your Java environment (for use with leJOS)
You can learn here how to switch firmware for the Lego Mindstorms NXT. If your NXT has leJOS (Java) firmware and you want to switch to Lego, read the first section. For the other way around: to switch from leJOS to Lego, read the second section ‘Install leJos firmware’. This article ends with a section … Continue reading Installing Lego firmware
Materials for the workshops given for the minor program HTHT Science 2 Society are available on Canvas. The “Arduino & Programming” workshop which is part of the minor “From Idea to Prototype”, introduces various prototyping techniques, divided into physical prototyping (using Arduino, Lego Mindstorms, LittleBits) and ‘Virtual’ prototyping, like creating App mockups. You can see … Continue reading HTHT Science 2 Society
