This proof of concept shows an interesting way of making robotic legs. They are using programmable spring actuators to make these legs function as though they had a “reflex”.  The builder pulls...

Although we’ve covered DIY ECGs before, sent in his version that gives an in-depth explanation of what to do with the collected data. He built a basic battery-powered op-amp-based ECG for under...

Solving the age old problem of… wait, what problem are they solving? These students at UC Berkeley have built a toilet paper dispenser prototype. Not only does it meter out an exact amount for...

Sometimes you find yourself thinking “this cell phone is far to compact and unobtrusive.”

[Noah] tipped us off to his work with Physically Engaged Electronic Instruments. He is building instruments, that while being electronic, require physical action to drive them. In the video after...

has undertaken something of a ‘Mount Everest’ of guitar modifications. He’s developing a Servoelectric guitar that trades frets for a keypad. It is still a guitar in the sense that it has a body, strings, and pickups to sense the strings vibrations and...

One day computers will exist in every part of our lives. You’ll be standing in the shower, lathering up  when Chantal, your holographic computer controlled AI partner, informs you in a cool voice you have a new email. How splendid, it must be the...

built a light box for an exhibition last year that displayed different colors statically. After showing it off, it went unchanged but future improvements remained in the back of his mind. Recently, he pulled it out again and hacked together a...

It’s not a bazooka, but this altered instrument makes it look like the player is toking off of some type of weapon. wanted to take the already mysterious sounds produced by a didgeridoo then capture and alter them electronically. The physical build of...

Starting a new robotics project and want to find the perfect servo for the job? It can be a real pain in butt sometimes. This is where ServoDatabase.com comes in. They’re compiling specifications and reviews on servos. We love seeing these databases...
