This Infrared Eye-Tracking Computer Mouse uses some interesting methods of creating a eye controlled computer mouse. The intent is the you would be able to ditch the desk mouse and simply put on a pair of glasses. The system would be a self contained battery operated system that doesn’t have you tethered to your computer with a cable. “We have a pair of 3-D printed glasses with plastic lenses.
The Spherebot would be a great way to design some unique Christmas Tree Ornaments. “Our Spherebot is made of two stepper motors and a servomotor; as mentioned, a motor serves to rotate the ball on the axis, while the second motor allows to move the marker around the circumference of the sphere. The servomotor is used to raise and lower the pen. To allow anyone to easily edit the
 If you are a guitar player and like tinkering with electronics this Open Guitar Pedal will probably be of interest. “The shield has three parts: The Input Stage or Preamp: Amplifies the guitar input signal and sends it to the Arduino microcontroller to be processed. Arduino Board: It does all the Digital Signal Processing (DSP) modifying the signal and adding the effect (delay, echo, distortion, volume…). The Output Stage:
  We have seen a bunch of useless machines in the past but this Microcontroller based Useless Machine is a lot more fun since unlike the original versions there are almost endless possibilities on what will happen when the switch is toggled. Rest assured the machine will turn it off, but how it will go about doing it will chance every time! With the clicks and knocks as it
The µCurrent GOLD – Precision Multimeter Current Adapter Kickstarter by our friend Dave Jones form the EEVBlog is in full swing. This is a big upgrade from the previous µCurrent that Dave was selling. The price is more than before but on a previous episode of The Amp Hour Dave was talking about some of the precision resistors that were needed for the Gold version. If I recall correctly

Jack Minardi hacked a remote control to allow it to be controlled by an electronic signal rather then a push button. This remote allows him to take control over the remote that can turn on 110 volt outlets. Of course you could simply use a relay and control the AC itself but there would be no Rube Goldberg aspect there… Although this system is nice that it is wireless
