Smart Ball Technology Has Reached Football, But The Euros Show Us It’s Not Necessarily For The Better

The good old fashioned game of football used to be a simple affair. Two teams of eleven, plus a few subs, who were all wrangled by a referee and a …read more Continue reading Smart Ball Technology Has Reached Football, But The Euros Show Us It’s Not Necessarily For The Better

PAWS ball helps calm people by breathing along with them

Breathing exercises – in which a person takes slow, deep breaths – have been shown to reduce stress and anxiety. Focusing on breathing in this manner can be difficult, however, which is where the PAWS “breathing ball” is designed to come in.Continue Re… Continue reading PAWS ball helps calm people by breathing along with them

Robotic Ball Bouncer Uses Machine Vision to Stay on Target

When we first caught a glimpse of this ball juggling platform, we were instantly hooked by its appearance. With its machined metal linkages and clear polycarbonate platform, its got an irresistibly industrial look. But as fetching as it may appear, it’s even cooler in action.

You may recognize the name  …read more

Disco Ain’t Dead: Blinky Ball Makes You Solder Inside a Dome

Disco balls take a zillion mirrors glued to a sphere and shine a spotlight on them. But what if the ball itself was the light source? Here’s a modern version that uses addressable LEDs in a 3D-printed sphere that also hides the electronics inside the ball itself.

Check out the video below to see the fantastic results. It’s a Teensy 3.6 driving a whopping 130 WS2812 LEDs to make this happen. (The sphere has the highest surface area to volume ratio!) There’s even a microphone and an accelerometer to make the orb interactive. Hidden inside is a 4400 mAh battery …read more

Gyro Controlled RGB Blinky Ball Will Light up Your Life

[James Bruton], from the XRobots YouTube channel is known for his multipart robot and cosplay builds. Occasionally, though, he creates a one-off build. Recently, he created a video showing how to build a LED ball that changes color depending on its movement.

The project is built around a series of 3D printed “arms” around a hollow core, each loaded with a strip of APA102 RGB LEDs. An Arduino Mega reads orientation data from an MPU6050 and changes the color of the LEDs based on that input. Two buttons attached to the Mega modify the way that the LEDs change color. …read more

Marble Chooses its own Path

[Snille]’s motto is “If you can’t find it, make it and share it!” and we could not agree more. We wager that you won’t find his Roball sculpture on any shopping websites, so it follows that he made, and subsequently shared his dream. The sculpture has an undeniable elegance with black brackets holding brass rails all on top of a wooden platform painted white. He estimates this project took four-hundred hours to design and build and that is easy to believe.

Our first assumption was that there must be an Arduino reading the little red button which starts a sequence. …read more

Mechanisms: Bearings

They lie at the heart of every fidget spinner and in every motor that runs our lives, from the steppers in a 3D printer to the hundreds in every car engine. They can be as simple as a lubricated bushing or as complicated as the roller bearing in a car axle. Bearings are at work every day for us, directing forces and reducing friction, and understanding them is important to getting stuff done with rotating mechanisms.

Rolling-Element Bearings

What first pops to mind when using the term “bearing” is probably something from the broad category of rolling-element bearings, like …read more
