If you’ve ever played with desk toys portraying a beach with liquids that splash around, this project by Lena Strobel, Gabriel Rihaczek and Guillaume Caussarieu takes things up several levels as a surf simulator that you can actually ride. The device features two parts — an oil/water wave diorama which sloshes around using a servo actuator and […]
Normally the 10-50 gigapixels of a DSLR are good enough for nearly any photo you can imagine, but if you need more—and don’t want to spend many thousands of dollars—then this clever setup by Jon Bumstead may be just the thing. His contraption uses a Nikon D5000 camera situated above a small photographic subject, which […]
You’ve seen self-balancing robots, where a pair of wheels suspend a mass above them in what’s known as an inverted pendulum configuration. As neat as they are, the “Augmented Arthropod” by Grzegorz Lochnicki and Nicolas Kubail Kalousdian puts a new spin on things. The structure for the build consists of three platforms separated on threaded […]
In the Earth’s atmosphere, a drone can adjust its heading by varying the speed of the propellers, and thus the thrust output of each. If you wanted to land something on a lunar surface, or maneuver a spaceship, the lack of atmosphere means a different technique must be used. While not going to space (yet), […]
If you’re a fan of novel timepieces, then you’ll want to check out Christine Thompson’s VFD Alarm Clock. The device features a USSR-manufactured IV-27V 7-segment tube, capable of displaying 13 numbers or letters via a 24V supply, though the MAX6921 chip used here means that only 10 grids are used. 10 characters, however, are plenty […]
While most 3D printers deposit melted plastic in carefully controlled positions to build up a physical model, a similar process called “bioprinting” can be accomplished with biological materials. Commercial bioprinters can cost tens of thousands of dollars or more, but as shown here you can make your own using the shell an inexpensive desktop machine. […]
Embedded programming using the Arduino IDE has become an important part of STEM education, and while more accessible than ever before, getting started still requires some coding and basic electronics skills. To explore a different paradigm for starting out on this journey, researchers have developed Flowboard to facilitate visual flow-based programming. This device consists of […]
While the hoverboard craze has faded somewhat, the good news is that this means their powerful wheel motors can easily be found on online auction sites. Lukas Kaul took advantage of this component’s availability and created his own “HoverBot,” which as shown in Felix von Drigalski’s video below, acts as something in between a radio-controlled […]
If your kids aren’t thrilled about doing chores, you could resort to a whiteboard, or simply create your own RFID tracking system like maker “alastair-a.” His project uses an Arduino Nano, along with an RFID reader and RTC module to track when a job has been completed. The chore is selected using a rotary encoder and […]
If you want to keep your Arduino projects safe, an electrical box is the traditional choice. But what if you want to apply protection directly to the board? In the video below, “TheRainHarvester” shows us a novel and inexpensive method for hardening a Nano from short circuits and other minor exposure by simply melting plastic […]
