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.

We live in an older house and the plumbing clogs up frequently (usually an hour before a dinner party). I rarely get good results from Draino or other lye-based clog dissolvers. I end up with a sink full of caustic swill that splashes on me when I vigorously agitate it with a plunger. A Drain Weasel works well for bathroom sinks, provided the clog is near the drain opening. The clog problem I had this morning, though, required more powerful clog-busting technology.

Boing Boing's barbecue gadget reviewer found a good, cheap grill on Amazon. But which add-ons, like an automated rotisserie, are worth buying? He investigates and tells all, right after this bite of chicken.
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.
