Hydraulically-actuated robots are nothing new, but normally they come with a battery or external supply of some sort. This lifelike robotic lionfish developed by Cornell and the University of Pennsylvania researchers, however, has its own artificial circulatory system that pumps synthetic ‘blood’ to help flap its fins and as the device’s power source itself. The […]
Alarm clocks of old—and certainly many of those today—require several button pushes to set things up properly. Maker Michael Wessel, however, decided to implement his own take on a more intuitive clock, creating a device that features three separate eight-digit seven-segment LED panels. Eight buttons allow for direct manipulation of each of the digits, with […]
As you experiment with Arduino boards and programming, you’ll likely have ideas that you want to test right now. Unfortunately, you can’t always have the entire project with you to try out. With that in mind, Khang Nguyen has designed the Portable Arduino Bot. This sci-fi-inspired device packs an Arduino Nano inside, along with an on/off […]
Having a light on your bike at night is important for safety, but what if those headlights could talk to others sharing the road with you? Well now it can, using the [Bike] Swarm by Alex Berke, Thomas Sanchez, and Kent Larson from the MIT Media Lab. Their device—or collection of devices—controls a bicycle’s lighting […]
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. […]
