How fast is the wind?

Design and build a 3D-printed windmeter

HOW TO MEASURE BOILING POINTS

An easy and accurate way to measure boinling points of liquids

A musical cardboard robot actor

A guide to engineer a moving and musical robot made of cardboard and a couple of arduinos.

This project consists of designing a roller coaster, based on the law of conservation of energy and making a model to test its operation.

Design a solar panel that rotates and faces towards the brightest light.  

A guide to engineer a rotation system for a solar panel with the aim of optimizing the energy production.

Static solar panels loss about half of the energy generation capacity of the day due to sun’s rotation. In this project we want to test the energy production improvement of adding a self-powered rotation system to the solar panel.

Sorting packages based on dimensions

The system discards only big packages (the sensor is set to a certain height; if a package reaches it, it is discarded)

This project is the Slovenian 2023 Thinkerlab Hackaton Winner!

Are you able to split water into oxygen and hydrogen?

Electrolysis of water is a highly efficient and cost-effective way to produce hydrogen gas, which can be used as a clean and renewable energy source. The process involves passing an electrical current through water, causing it to break down into hydrogen and oxygen. This laboration aims to test this process. 

Calculate a resistor value and its current flow

Learn how to apply a Voltage Divider and an Arduino to find the value of an unknow resistor. Then, using the Ohm Law, calculate the amount of the current flow.

Could you measure and identify a tree in a park?

Starting from a map analysis, couples of students will calculate the tree measurement point in a park. Then, they will have to join the measurement point and discover how much the tree is high applying simple math rules. Finally they will have to recognise the tree specie using mobile apps and compare results with their classroom mates.

A carbon fibre heater controlled by a temperature sensor

Carbon fibres can be used in many different ways, yet they are seldom used as heating bodies. To successfully use carbon fibres as heating bodies the necessary amount of fibres is required due to their electrical resistance, which varies with the quantity and the length of the fibres. Fibres heat up rapidly; that’s why we can easily control them using a temperature sensor and PLC Arduino Uno. To set up the system, a set of products is prepared, and a basic program, which can be changed or upgraded. The electric circuit diagram of the components is also included.
