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

Spinner is a toy intended for relaxation of individuals during a constructive thinking process. It also helps individuals who have a deficit in a particular area to concentrate. Spinner is a spinning/ rotating toy with a bearing that has been made with a 3D printer on the basis of 3D modelling using Onshape software.

Blow the light!

This project is a very cheap and sustainable way to generate light. The project involves the design, manufacture and assembly of the windmill itself, and the connection between the windmill, the electric motor and the light bulb

Protect cyclists hands!

The project Is focused on the shocks that cyclists suffer when they go downhill or simply go on a mountain route. In this case, cyclists suffer many blows to their hands, due to brambles or tree branches. This is why a low cost 3D printable protection has been designed. This protection has three different parts. All of them can be 3D printed, but in this case, only two of the pieces are printed, the third one is created with a reused material.

Can two arduinos exchange data?

Digital communication refers to the transmission of data, information, and messages through digital devices and channels. With the increasing reliance on technology and the Internet, digital communication has become a crucial aspect of modern society. In order for this to work a common framework is needed. In this laboration you will set up a basic communication protocoll between two Arduinos.

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!

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.

Assemble and program your desk clock!

Using some 3d printable pieces, an Arduino board and three cheap stepper motors you can apply your maths and programming skills to realize an easy desk clock. You can also personalize the final result mounting the clock inside a recycled box!

To start with this project you can find here the STL files for your 3d printer, the electrical diagram and an example of the Arduino code.
