When a solid substance is heated the increase in energy manifests itself in the form of an increase in temperature. If the heating rate is constant the temperature increase is also constant as long as there is no change in the structure of the substance. At the time when some kind of transition is initiated

The Candied Dead Baby is an Arduino-controlled interactive halloween decoration. It has been designed, created and assembled by three industrial design engeneering students from Elisava. Using servomotors and ultrasonic distance sensors as well as a buzzer, we’ve designed a product that when an ultrasonic sensor catches movement in front of it, activates a servomotor and a

This project is a trash can that recognizes and classifies garbage automatically. Use Machine-Learning and Arduino in Scratch. How it works 1. Camera takes an image of garbage. 2. Machine-Learning model recognizes the classification of garbage by the image. 3. Electrical and mechanical parts drive the garbage into diffrent palce by its classification. Beginner-friendly Machine-Learning, Block-coding and
AI Auto-Classify Trash Can Continue Reading
Hello and welcome back to another Instructable. In the previous two Instructables, I have shown you how I created PCB coils in Kicad using a Python script, covered the basics of an H bridge, and showed you how I will be using them to control the segments of the 7-segment mechanical display. Make sure you

A key factor when building a pinewood derby car is its weight. The Boy Scouts of America and other organizations specify a weight of no more than 5 ounces. To improve performance many builders will add as much weight (mass) as possible up to that maximum allowable weight limit. What is often overlooked is the

This project is loosely inspired by the laser harp of Jean-Michel Jarre. Instead of lasers however, it uses eight SHARP infra-red distance sensors, the variants with the longest range of 35 to 40cm. These sensors are laid out in a row to provide rows of 8 notes at 3 different height levels giving a total
