This is just one example of several pairs of spooky eyes which light up [Vato Supreme's] bushes this Halloween. The quick and inexpensive build process make it a perfect diy decoration. Each eye is made up of a ping-pong ball and an LED. But that alone won’t be very spook as the entire ball will [...]

Looking at this 17-stage Great Ball Contraption makes us think that [Skiyuky] should be working in industrial automation. The build, which has been assembled from an untold volume of LEGO parts, moves a reservoir of round plastic balls around a circuit. Each module exhibits a different mechanical way of handling the parts. It’s certainly not the first [...]

Knowing that I’m always happy to get something new and glowy, my wife brought home a cheap “floating pool light” that she found on sale for roughly $10. This is a large white floating ball that has LEDs inside and cycles through different colors. Meant to be put into a pool for neat effects, we [...]

What should you do with your down time between sophomore and junior year at MIT? You better build something awesome. [Christian Reed] didn’t disappoint with his newest creation. He calls it the Ping Pong Mauler and we think that’s an appropriate name. It doesn’t just lunch a ball, it belches forth a relentless barrage. He [...]

Perennial Hackaday favorite [Dino] has an article in this months Make magazine. It’s an automated ball launcher that allows you to play fetch with your dog without wearing your arm out. The powerhouse inside [Dino]‘s ball launcher is a windshield wiper motor powered by an 18 Volt cordless drill battery pack. When a ball in dropped into the [...]

This guy is about to toss the blue ball half way between the book shelf and the waste basket. By the time it gets there the waste basket will have moved into position to catch the ball perfectly. It’ll do the same for just about anything you throw. We’re unable to read the captions but [...]

[mobile_earth_explorer] sent in an Instructable he put together documenting an Android-controlled rotating monitor stand he built. The stand itself is three disks turned on a lathe out of a 18mm thick board. After turning these disks, [mobile_earth_explorer] hopped over to his bench grinder and made a semicircular tool to carve out the track for the ball [...]

This is a blinky ball that [David] designed, built, and programmed himself. Does it look familiar? It should, he took his inspiration from the original prototype, and the Hackerspace-produced derivative. [David's] version is not as small, or as blinky, but in our minds the development process is the real reason for building something like this. [...]

We get a ton of tips about Kickstarter projects. Here is a great example of what we need to see in order to feature one of them. This LED Blinky Ball developed by Null Space Labs is the target of a rather ambitious fundraising campaign. But in addition to the fundraising write-up they’ve shared extensive [...]

[Andrew] and his brother had some time (and a lot of ping pong balls) on their hands, so they decided to have some fun and built a remote-controlled ping pong ball turret. Arduino aside, the turret is cheap and easy to build as [Andrew’s] writeup explains. The firing mechanism was constructed using a pair of [...]

While city engineers were setting up the multicolored ball of lights in Times Square this year, [Phil] at adafruit was busy designing the X2 Time Ball, a disco icosahedron perfect for celebrating the new year. The ball is made of 20 acrylic triangles zip-tied together into an icosahedron. On each face, six RGB pixels light up [...]

[Dino] wanted to make this New Year’s celebration a bit more interesting, but he can’t make it to New York for the ball drop. Instead, he decided to make his own mini display in his workshop. Obviously he’s working with a slightly smaller budget than the folks at Times Square, but we think his display [...]

[Lizzie] from LustLab sent in her Ball of Dub that turns a few accelerometer and a digital audio workstation and turns everything into an aural experience of wubs and dubs. The Ball of Dub can turn just about anything into dubstep, and does so with a fairly interesting user interface. There isn’t a build log [...]

He came up with a 10 cm LED ball (Russian, Google translation) that has a matrix of 256 LEDs wrapped around its surface. The ball’s structural support is its [...]

This odd-looking ball can automatically take a panoramic image whenever you throw it up into the air. Seriously, that’s then entire set of operating instructions for the device. Inside, a 3D printed frame hosts an array of 36 cellphone cameras, each capable of taking a two megapixel image. Also included is an accelerometer. When it [...]

[Jack Gassett] is developing a new breakout board for an FPGA. The chip comes in a ball grid array (BGA) package which is notoriously difficult to solder reliably. Since he’s still in development, the test boards are being assembled in his basement. Of the first lot of four boards, only one is functional. So he’s [...]

Hackaday forum member [machinelou] says he’s been fascinated with remote controlled hamster balls for quite some time. Inspired by a ball bot he saw on a BBC show, he finally picked up a 12″ plastic ball and got to work. He used a small drill to provide the power required to roll the ball, and [...]

A while back, [Dino] built an automatic ball launcher for his dogs, but he wanted to revise it to make it smaller and a bit more user-friendly. While watching an episode of “Prototype This”, he came across a great idea to improve his launcher, so off to the workshop he went. He repurposed a power [...]

Hackaday forum user [arfink] has shown us a brilliant practical joke he built. This is a magic 8 ball that will blind you with a flash when you flip it over. Have you ever been in a room with one of these and not flipped it over? Neither have we. Using a basic flash circuit [...]

This kinetic sculpture is a ball bearing’s paradise. Not only do they get a cushy ride around two lift wheels but there’s a variety of enjoyable obstacles they can go down. The first is a vortex made from a wooden flower pot which sends the balls randomly down one of two possible exits. From there [...]

In what is surely becoming an ever-growing Rube Goldberg machine, [Dan] updated his gum ball dispenser to include a robot arm. We looked in on this human lab-rat experiment that rewards successful maze navigation with bubble-gum just about a year ago. As you can seen in the video after the break he’s added several new [...]

This is a ball mill used for refining materials into a fine powder. [Jpoopdog] built it in two parts, a base and the tumbler chamber. The base itself is build using LEGO wheels as rollers. The motor and controller from an NXT kit is used to drive the rotation, with programming to stop the mill [...]

The idea of the Great Ball Contraption is to take modules from many builders and combine them into one large machine. The modules need to find some way of moving LEGO soccer balls and basketballs from an input point to an exit are that passes them onto the next module. Some of them sort the balls, but [...]

[Mitchel Humpherys] and his fellow developers didn’t just develop a maze-solving algorithm, they also built a ping-pong ball maze platform that is computer controlled. Using a webcam the computer picks up the high-contrast maze by peering down from above, calculates the solution, and moves the ping-pong ball to the goal using two different tilt servos [...]

We’re not sure what the advantages are to this layout though. Anyone care to enlighten us? Even though we hadn’t seen this style, [...]
