Nerf Vulcan Sentry Gun

   Using some guidance from this page, BrittLiv has built one great looking Nerf Vulcan Sentry Gun! The spring has been swapped out to allow for more powerful and higher speed dart. The targeting looks like  it is fun since it will track people and actively fire on them unless they are wearing the Instructables logo on their shirt!  

Energy Harvesting Roads and Sidewalks

    Are sidewalks and roads of the future going to be generating energy to power things around them? Some embedded Piezo Generators might be just the thing we need. This is an interesting concept. Only thing is that laying a sidewalk or road with this technology is sure to be expensive. Will the energy savings outweigh the cost of installation and maintenance? Nice thing about this technology is that it

Skot 9000 DigitGrid

  Check out the Skot 9000 DigitGrid. It is a huge grid of 7 segment displays that can be used to display a picture or even a video in a crude way. The result is beautiful! Thanks for the tip Stan. “The DigitGrid is an array of seven-segment displays. There are 4096 LEDs, forming 512 7-segment digits (they are actually 8 leds each if you count the decimal point). Every

Space Station Lamp

    If you want to be notified whenever the Space Station is flying overhead this Space Station Lamp project by Nathan from Mechanical Integrator is sure to help out. A number of LEDs edge light a piece of frosted plexiglass and a Teensy microcontroller does the work. Some Python code is used to check to see when the Space Station is over head. If you are interested in making

Jeremy Blum Remote Controlled Graduation Cap

    Congrats to Jeremy Blum for graduating from Cornell University! He made a cool Remote Controlled Graduation Cap that he controls using a custom built wrist control box. The cap has an RGB LED in it and is capable of not only grabbing user submitted color suggestions but also a variety of pre-programmed ones. If you would like to see how it works Jeremy has made it open source

Control Microbes with your Mind

  Thanks to Geva for sending in this great project. A brain monitor is connected to an Arduino so it can detect when the user is concentrating. When this happens a mild electric current is applied to the water in which there are hundreds of microbes swimming about. As soon as the current is applied they immediately start swimming towards the top of the screen where the negative pole is.

Hand Controlled Tetris Like Game

  This Hand Controlled Tetris Like Game uses an Altera FPGA to captures a video signal and looks for a players hand skin color. The system tracks their hand movements and looks for the user moving their hands forward and back by determining how tall the skin colored object is over time. The goal here is to prevent the falling tetris like blocks from falling by rapidly pushing and pulling
