Logic Gates Under (Air) Pressure

We’ve always been fascinated at the number of ways logic gates can spring into being. Sure, we think of logic gates carrying electrons, but there are so many other mechanical means to do the same thing. Another method that sometimes has a practical use is fluidic or pneumatic logic. We guess [dAcid] has a similar interest since he’s written two posts on how to construct the gates. One post covers making them with ordinary tools. The…

Project Kino: Robotic Jewelry And Tech Accessory

Researchers from MIT and Stanford are taking the ‘person’ in ‘personal assistant’ to mean something more literal with these robots that scurry around on the user’s clothing. Project Kino — inspired by living jewelry — are robotic accessories that use magnetic gripping wheels on both sides of the clothing to move about. For now they fill a mostly aesthetic function, creating kinetic accents to one’s…

It’s an Angle Grinder! No, it’s a Floor Sander!

Faced with the potentially arduous task of sanding a wood floor, what would you do? Hire a pro? Rent the proper tools and do it yourself? Perhaps even shell out big bucks to buy professional grade tools? Or would you root around in your junk pile and slap together a quick and dirty floor sander from an old angle grinder? That’s what [Donn DIY] did when looking at the wide expanse of fresh floorboards in his new sauna. Never one to take…

PiCorder: Raspberry Pi Stands in for Stone Knives and Bearskins

In a classic episode of Star Trek, Spock attempts to get data from a tricorder while stuck in the 1930s using what he described as “stone knives and bearskins.” In reality, he used vacuum tubes, several large coils, and a Jacob’s ladder. Too bad they weren’t in the year 2017. Then Spock could have done like 0 and used a Raspberry Pi instead. You can see the result in the video below. The build starts with a…

Live Stream to YouTube by Pointing a Box and Pressing a Button

YouTube has the ability to do live streaming, but [Tinkernut] felt that the process could be much more straightforward. From this desire to streamline was born the Raspberry Pi based YouTube live streaming camera. It consists of a Raspberry Pi with some supporting hardware and it has one job: to make live streaming as simple as pointing a box and pressing a button. The hardware is mostly off-the-shelf, and once all the configuration is done the…

Levitate liquids and other tiny objects with this DIY device

If you’ve ever wished you could levitate tiny drops of liquid, small solids, or insects in mid-air, new research has you covered. That’s because Asier Marzo, Adrian Barnes, and Bruce W. Drinkwater have developed a 3D-printed, Arduino Nano-controlled acoustic levitator. Their device uses two arrays of 36 sonic transducers in a concave pattern, which face each other in […]

The GuitarBot will strum you a song

While many Makers have musical skill, others attempt to compensate for their lack of it by producing automatic instruments that play themselves. One such attempt started in 2015 as a collaborative project between three University of Delaware professors as part of an initiative known as “Artgineering.” This was meant to “create a public spectacle… to demonstrate […]

Maker creates his own coilgun using an Arduino Nano

If you suppose that electromagnetically-propelled projectiles are strictly the purview of well-funded government research labs, think again! Using two sets of coils wrapped around custom 3D-printed base structures and an Arduino Nano for control, YouTuber “Gyro” created his own coilgun capable of propelling steel fast enough to dent a piece of wood. When fired, a photodiode at […]

Hardware Hump Day: The Great Ceramic 3D Printer Experiment, Part II

As parts for my ceramic 3D printer continue to trickle in, I have been slowly moving forward on the great experimental build (see part 1 here). With each step, it has become increasingly clear that the OS plans are more of a general guideline than a set of steps or rules to follow. Much planning, tinkering and redesigning is required to make all the parts cooperate together. I’m starting to understand the need for the Google group, which…
