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. [...]

[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 [...]

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 [...]

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’ve seen several different balancing bot styles over the past few years, but this one is new to us. The BallP, short for Ball inverted Pendulum, balances on top of a ball. 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, [...]
