Tetris was as a perfect complement to Nintendo’s original Game Boy when it came out in 1989, and now “Copper Dragon” has been able to fit an entire system for it — sans monitor or speakers — inside of a faux NES controller.
Impressively, this feat was accomplished with an Arduino Nano and a few passive components, producing not only very believable grayscale blocks, but also playing the familiar tune to accompany the video.
The “world’s most popular open source robot for education and research” has received a major upgrade with two modular TurtleBot3 models from Open Robotics that run Linux and Robot Operating System (ROS): – Burger version, based on a Raspberry pi 3 which runs on a Broadcom BCM2837 with four 1.2GHz Cortex-A53 cores and a VideoCore…
Some time ago we had introduced you to the Torpedo switching power supply, a particular kind of DC/DC power supply called SEPIC capable of supplying 5 V from several external supply sources, such as an external voltage between around 3.5 and 20 V, the 5 V coming from a USB connector or the 3…
You may have a 3D printer or other “digital” tools like a laser engraver or CNC router, but what if you want to work with Styrofoam? As How To Mechatronics demonstrates in his latest project, many of the same techniques used there can be implemented to make your own Arduino-powered hot wire cutter. This build…
In this project we will see how to build a home automation greenhouse with Arduino Uno that allows you to grow plants even in unfavorable weather conditions. In addition to recreating an optimal environment, a domotic greenhouse allows the automation of fertilizer administration and controlled irrigation. Furthermore, by monitoring environmental factors in real time, you…
We recently presented our Open Source Solar Lawn Mower, project to Boca Bearings Innovation Competition and it has been selected and you can now vote for it! This lawn mower uses only energy from the sun and does not require any external power source, that can operate in areas not covered by the electricity service. Is very simple…
The low cost of sensors and components allows us to build small gadgets and tools that were unthinkable just a few years ago. In this project, a “bubble” level has been created, which is a tool used to determine if a surface is perfectly level. The level was constructed using an accelerometer and an…
