Microfluidics deals with the manipulation of tiny amounts of liquid, and as such, specialized equipment must be used for any sort of measurable experimentation. While you could purchase an expensive commercial solution, the Poseidon system—developed by students at the California Institute of Technology—presents an excellent open source option which can be built for a fraction […]
Do you like grilled cheese? Would you rather not make it yourself? If so, then the Cheeseborg by Taylor Tabb, Mitchell Riek, and Evan Hill could be the perfect device for you! This assembly line-like robot first stacks bread-cheese-bread using a vacuum gripper, and passes the unheated sandwich onto the grill via a pusher mechanism. […]
Whether one of your senses is weak or non-existent, or you would simply like a way to augment your perception and control options, the Cthulhu Shield can be applied in either situation. The device takes the form of an Arduino Uno or Mega shield, with a strange flexible electrode setup that is placed directly on […]
Apparently not satisfied with available timekeeping devices, ElegantAlchemist crafted a unique clock using an Arduino Nano, an RTC module, and three formerly 1000VAC analog meters. The first order of business for the build was converting the meters into something that could traverse its range with only 5V, accomplished by replacing the stock resistor, diode, and […]
Waking up before 9am can be a challenge for Nikodem Bartnik, but he also hates to waste time sleeping when he could instead make something. In order to help him with this “joyous” task, he assembled a line-following robot that scoots his phone out of the room in the morning, forcing him to get out […]
When we last saw this omni robot by Jeremy S. Cook, it was lurching around under Arduino Nano and Bluetooth command. After much work, he finally has it to a state where it rolls nicely on a flat surface—even carrying a little strandbeest at just after 8:30 in the demo video. The biggest revision for […]
Martin Mihálek took the leap into standing desks, and purchased a SKARSTA table from IKEA. Although being able to adjust things by hand is useful, who wants to do that nowadays? Instead of manually cranking it every time, he—with help from iLLiac4—decided to augment it with a motor in order to lower and raise things […]
For the sixth year, we are inviting the open source community to join us for Arduino Day 2019 on Saturday, March 16th! Arduino Day is a worldwide celebration of Arduino’s birthday. It’s a 24-hour-long event—organized by both the community and our team—where those interested in Arduino get together, share their experiences, and learn more about […]
If you wear a self-winding watch—which uses your natural motions for power—you might notice that it stops working if it’s left off your wrist for too long. To avoid these situations, watch winders are available to turn them automatically, but tend to either be very expensive, or cheap and noisy. With a bit of hacking, […]
The See ‘n Say is an educational toy that originated in the 1960s, speaking out whatever the child pointed to on a dial. The device has evolved over the years from a mechanical sound mechanism to one that uses electronics in its design, which inspired Andrei Aldea to convert one of them into an EEV […]
