Nathan Peterson built this fantastic "juggling" robot that can be programmed with different juggling patterns and handles more than five balls.
"I believe this is the first juggling robot to juggle more than 5 balls," Peterson says. "Yeah it's not toss juggling (into the air), but that would be my next project."

The PocketLab is billed as a "Swiss Army Knife of science." Launched via Kickstarter, the small device contains numerous sensors to measure acceleration, force, angular velocity, magnetic field, pressure, altitude, and temperature and send that data to smartphones or laptops. According to inventor Clifton Roozeboom, it's a tool for students and citizen scientists who can't afford to spend tens of thousands of dollars on lab equipment and will get the data they need from this $100 gadget. From IEEE Spectrum:
“If you are doing a classic experiment in AP physics, you might have, say, a track and a pulley and you want to attach a sensor to a cart to measure acceleration, force, and momentum transfer,” says Roozeboom. “The typical gear available is wired, plugs into a specialized handheld gadget with a host of menus to navigate. The students spend a lot of time understanding how to use the gear instead of learning concepts.” In other traditional physics experiments, Roozeboom says, the device can be attached to a rocket to study projectile motion, stuck to a pendulum to look at harmonic motion, or placed inside a tube to measure changes in pressure with volume.

This fantastic sculpture by Clayton Boyer will delight, amaze, hypnotize, and/or induce motion sickness. He's posted the plans for sale and you can see how others have interpreted his basic design in this Flickr pool! Boyer writes:
This is Zinnia, a spring driven kinetic sculpture that will quietly run about 40 minutes on a full wind. Each of the two display wheels is 24" (61cm) in diameter, and as they change rotational speed and direction they create a variety of visually interesting shapes within the sculpture ~ as well as the contrasting shadows it projects against the wall behind. This is a very easy project to build and a great place to begin your kinetic sculpture and clock making journey. Zinnia's included wheel design is only one example of display wheel possiblities; you can create your own designs! The basic motive mechanism of the Zinnia will easily accept a wide variety of other display wheel sizes, shapes and forms. The possibilities for other variations in display wheel shapes is only limited by your imagination!

Developed by an 8-year-old maker named Omkar, the O Watch is a 3D printable, programmable, smart watch kit for kids. Omkar has launched a Kickstarter to scale up the O Watch so other kids can use the platform "to learn programming, 3D printing and crafts." Support it! Read the rest
If only all computer interfaces were as gloriously sci-fi as this excellent "DIY Overhead Control Panel" hand-built by a maker called Smashcuts. It features a slew of LEDs and 100 programmable buttons and switches that activate shortcuts on his PC, open apps, control volume and screen preferences, etc. Read the rest
