Vadim Panov wanted a way to automatically restart a PC that was simple and cheap to make. For this task, he turned to an Uno due to its wide availability; however, any Arduino board with at least one digital I/O pin and a USB-enabled serial port will work. The device sends a “hello” string to […]
For a class assignment, Matt Robb along with teammates Kara and Andrew needed to make a project using an Arduino and various other components. What they came up with was a carnival-style game that uses a stepper motor to rotate three targets containing IR sensors out of a nicely-painted cardboard box. An Arduino Uno provides […]
When dealing with robotics and other electronics projects, it can be important to know how many revolutions a motor is making. From here, you can infer the distance that your device has traveled, or any number of other important variables. If you’d like to get started with this type of sensing, this electronoobs tutorial will show […]
Tired of cleaning your house? A robotic vacuum may be the logical solution, but if you’re “theking3737” something off-the-shelf just isn’t quite cool enough. Created as part of a school project, he was responsible for the hardware design, while a fellow classmate took care of the programming. The DIY device uses an array of what appear […]
Hacker “wesgood,” apparently not satisfied with randomly checking the office coffee pot to see if a fresh brew was available, decided to make his own notification system. His device uses a current sensor to monitor power usage of the coffee pot, and after some observation, he was able to pick out its brewing pattern—7A at […]
Moscow-based artist ::vtol:: is back again with an interesting interactive exhibit entitled “you, me and all these machines.” His latest work, a collaboration with Lovozero, allows two participants to produce otherworldly vocals together. One participant wears the device, which points a directional microphone under the control of the other participant at her mouth using a servo […]
If you’d like a split-flap display with numbers and letters, options tend to be quite expensive. This though was no problem for hacker “scottbez1” who reports that after “only” two-plus years of work, he has produced a split-flap assembly that plugs into an Arduino Uno as a sort of external shield. The device employs inexpensive stepper […]
On July 20th, 1969 man first set foot on the moon with the Apollo 11 mission, or so they say. If it was faked, or so the theory goes, one would think that there were a few details that don’t quite add up. One such theory is that the hatch on the lunar module isn’t […]
Water normally falls from the sky to the ground, the time fountain from hacker isaac879 appears to work much differently. As shown in the video below, water droplets somehow levitate from a circular orange apparatus to a blue one on top. The trick here is that the water isn’t actually falling up, but appears that way […]
After discovering capacitive touch interactions with a Makey Makey device and an Arduino Leonardo, Jason Eldred realized it could also be used to control the Unity game engine. After a night of hacking, he had a basic interface that could change the scale of a virtual circle. From there, he teamed up with Alex L. […]
