2-way Audio Crossover: I designed a simple 2-way passive audio crossover, consisting of 2 power inductors and 2 capacitors. This makes for a second-order design or 12 dB/octave. This order is commonly used in passive crossovers as it offers a reasonable balance…

Kaiten Speaker: Originally designed as a Christmas present for my parents, these speakers took several iterations until I decided to finally post them online a full year later. The request was for speakers that can act as a surround sound system with our…

How do we know that planets exist outside of our solar system? While too far away to observe directly, with extremely sensitive equipment like the Kepler space telescope it’s possible to detect changes in light as these exoplanets pass in front of a star.…

Magnets are amazing devices, and as demonstrated by Instructables community manager Troy Hawkins (AKA "tomatoskins"), they can even be used to mysteriously tell time. His project features magnets hidden behind a classic walnut veneer to rotate a pair of ball…

When you purchase a spool of thread or wire, you expect it to be relatively uniform, spun in place with automated machinery that has been developed over hundreds of years. Researchers from MIT’s Media Lab, however, have come up with what could be the next…

Will Cogley, known for his awesome animatronics, has created a robotic mouth that's already a work of art and could form the basis of something even more amazing. 



The device features an array of servo mechanisms to actuate its jaw, forceps, cheeks, and…
