Rolls of Lego tape!

Nimuno Loops are rolls of Lego-compatible adhesive tape. Genius idea and no surprise that they've blown wayyyyyy past their Indiegogo goal to manufacture the stuff.

Imagine being able to build around corners, on curved surfaces, or even onto the sides of that sailing ship you've just spent hours building. You forgot to engineer a point of attachment for that sweet dinosaur-smashing cannon? No problem. Snip a length of Nimuno Loops, stick it on the hull, mount your cannon and be on yarr way.

Exquisite Rube Goldberg-esque machine plays "Here Comes the Sun"

Neil Mendoza created this fantastic electromechanical band as part of the artist-in-residence program at Autodesk:

The rock band is composed of electromechanical instruments that make music with rocks by throwing them through the air, slapping them and making them vibrate. The song that they're playing, Here Comes the Sun, is biographical, describing the daily experience of a rock sitting on the ground. The rock band is made up of the following members...

Pinger - fires small rocks at aluminium keys using solenoids. Spinner - launches magnetic rocks, Hematite, at pieces of marble. Rocks are launched by spinning magnets using Applied Motion stepper motors. Slapper - slaps rocks with fake leather. Buzzer - vibrates the plunger of a solenoid against a piece of marble. The whole project is controlled by a computer running a MIDI player written in openFrameworks talking to a Teensy. The machines were designed using Autodesk Fusion 360 and Autodesk Inventor.

He posted plans to make your own mechanical xylophone at Instructables.

DIY machine sorts M&Ms and Skittles by color

William Pennings built this wonderful machine that automates the arduous but necessary task of sorting M&Ms and Skittles by color. (Insert Van Halen joke here.)

"It's pretty quick and sorts about 2 pieces of candy per second" Pennings says. "It uses Arduino microcontrollers and stepper motors for quick and precise movement. A TCS34725 color sensor performs the measurements. Furthermore, the device is equipped with LEDs in several spots which nicely complement the overall look of the machine."

Children are stupid. Be smart, and secure each room for a stupid person

Brock and Bowdy were doing what toddlers do: being stupid. In the process of trying to climb their dresser via the drawers, they tipped it over, pinning Brock. Luckily Bowdy was able to free his twin brother, but these incidents are common. Ikea recently recalled several dressers for the same problem that led to fatalities. If you know or care for seniors, you need to senior-proof their living spaces, too. Read the rest
