Stars appear to stand still, but wait a few minutes and they won’t be in quite the same place. This means that if you want to take a long-exposure image of the sky with your DSLR you’ll have to either embrace the streaks, or use tracking hardware to compensate for this movement. Naturally, this specialized equipment…
3D scanners are amazing tools that literally let you turn everyday things into three-dimensional computer models. As seen on Reddit, if you want to make one yourself — using little more than a spare Android phone, Arduino, stepper motor, and 3D-printed parts — the AAScan by QLRO could be an excellent option.

We introduced this concept last year, and have launched three games so far. Our final game of 2019 was SumoBots Battle Royale — where players from anywhere in the world can fight real robots in a battle royale-style arena. The aim of the project was to have the game run semi-autonomously, meaning that the…
Music and synchronized lighting can be a beautiful combination, evident by panGenerator’s recent installation that was commissioned by the Meskie Granie concert tour in Poland. The interactive sculpture was comprised of 15 drums that trigger waves of light traveling toward a huge helium-filled sphere floating above the area, appearing to charge it with sound and light…
If you have multiple applications open in Windows, you may want one to be louder than the other, but what if you want to adjust levels with physical sliders like an actual DJ? If that sounds interesting, check out this controller by “Aithorn.” The device uses an Arduino Nano to read signals from each slider and pass this…
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,…
Nixie tubes are, of course, an elegant display method from a more civilized age, but actually powering and controlling them can be a challenge. This can mean a great project and learning opportunity, but if you’d rather just skip ahead to programming these amazing lights, then Marcin Saj’s IN-2 binary Nixie clock is definitely…
Researchers in Thailand have developed a ZigBee-based wireless monitoring solution for off-grid PV installations capable of tracking the sun across the sky, tilting the panel hourly. The elevation for the setup is adjusted manually once per month for optimum energy collection. The prototype is controlled by a local Arduino Uno board, along an H-bridge motor driver to…
Key features include the ability to: Execute your Arduino sketch step-by-step while it’s running on your Arduino board! Pause your sketch execution placing breakpoints. Inspect variables values during execution. Initially supporting SAM D21 boards, the Arduino Pro IDE Debugger is available for Windows, Mac OS X and Linux64. You can try the Arduino Debugger…
The South Florida Science Center recently commissioned a beautiful new 10” aperture refactor telescope. Its dome, however, was opened by hand; so in an effort to modernize this part of the setup, Andres Paris and his brother added a windshield wiper-style DC motor to automate the process. More info
Sorting algorithms are the basic algorithms for beginners who want to learn computer science or programming. But sometimes you will get confused about how these algorithms work. Thus, there are plenty of visualizations of these sorting algorithms for beginners. But there are no visualization methods based on LEDs. Then I decided to implement one with…
After developing the Arduino based Pick & Place Robot the idea was to develop an Artificial Intelligent AI-based line following robot. Developing a simple line following robot was good for the beginner just what it needed to add some sort of infrared sensors instead of servo motors in my recent project. “The idea was to…
