LED candles can provide a nice sense of ambiance, without the inherent associated risk of fire. For better or worse, however, they don’t normally respond to air currents. Paul Dietz, however, shows that this kind of response is actually possible, as an LED’s forward voltage drop is affected by how well it dissipates heat due […]
In order to help those with visual impairments navigate streets, college student Satinder Singh has come up with an innovative solution that literally pokes the user in the right direction. Singh’s system, called DeepWay, uses a chest-mounted camera to take images of the road that a wearer is walking down, then feeds this information to a […]
If your kids (or you) have somehow gotten tired of playing with LEGO bricks, Lenka Design Workshop has a great way for you to breathe new life into this unused pile. Their game enclosure consists of a 32×32 LEGO baseplate, along with walls made of blocks to support a clear acrylic cover. This in turn […]
If you’re ever wanted to make something awesome, but thought that you just didn’t have the right tools to do so, this soda fountain by “The Wrench” could provide the needed inspiration. The project uses an Arduino Nano to control a small air pump via a relay, which turns on when a glass is the […]
Many DSLR cameras can be operated with a simple infrared signal, making them perfect targets for Arduino control. Travis Antoniello took advantage of this with his brilliantly simple 3D scanning rig. Electronics are handled by an Arduino Uno, which commands a stepper motor to rotate a scanning platform 10 degrees per photo. After rotation, it […]
As seen here, Alex Mikes enjoys reading his Kindle in bed at night, but prefers to use a stand rather than hold it in his hands. The one disadvantage to this is that one normally has to lift his or her hand up to change pages. Thanks to a clever bit of engineering, Mikes only […]
While “Boardwalk” and “Park Place” may not mean anything to you outside of the game of Monopoly, there is a plethora of custom versions to suit your particular interest. If you enjoy the world of Skyrim, then you need to check out this board by Charles Ledford. The build features an anodized aluminum playfield coated in […]
When Hunter Irving spotted a knockoff Thomas the Tank Engine toy at a thrift store, he simply had to buy it, telling himself that he’d turn it into an animatronic contraption at some point. While these kind of promises often go unfulfilled, Irving converted it into an egg-shaped, karaoke-singing robot, with a mouth and eyes […]
Does a rocket need to use a certain type of fuel, or even be capable of spaceflight? While James Bruton’s build might not fit everyone’s definition of this type of craft because of its electric ducted fan (EDF) propulsion, it does face the same major challenge of controlling a tall pipe-like structure from thrust coming […]
Split-flap displays show information using characters changed by an electric motor. While they’ve largely been replaced by more modern means, hobbyists like “gabbapeople” have been keeping this this technique alive, in this case as a four-character IoT weather display. The device is built using laser-cut plexiglass, and uses four individual servos to actuate the character […]
