"The project was a 5 ft tall lantern composed merely of junk wires, light bulbs and considerable amount of electronic components. The lantern was synchronized with monotone tunes. There were 5 different songs used and every song has different light sequences."

"The following is my entry of a small 3-axis CNC robotics platform into the African Robotics Network (AFRON) Ultra Affordable Educational Robot 2013 Design Challenge. The Tiny CNC robot, despite its minimal design, is a versatile 3-axis CNC robotics platform which can be customized to perform a variety of useful functions. To demonstrate its versatility, I have augmented it with a pen to serve as a small drawing robot. "

"Computer controlled Etch-a-Sketches are not rare things. In fact, there is at least one other such device made with the Raspberry Pi. However, I think my Etch-a-Pi design is pretty reasonable, so I’m describing how to build it here."

"The goal of this project is to design, code, and build a new controller board for the Wowwee Alive Animatronic Elvis bust. These have been discontinued, but can still be found occasionally through the usual trading means (eBay, etc..)."

"What’s Halloween without a carved pumpkin? And what’s the point of lighting the pumpkin with a candle when we have LEDs?…The LEDs flicker for 30s when someone is close to the pumpkin. Notice the IR-detector in the nose."

"The ATTiny Candle is an LED candle. It uses a high brightness LED and some software to mimic the look of a traditional candle without the dangers associated with an open flame. I imagine they could be useful as movie props where you cannot afford to have a candle go out during a take or in your home in places not suitable for traditional candles such as in a wall niche or alcove."

"The goal of our project was to create both the hardware and software platform that can be used as a adaptable haptic data visualization device…Sure, it’s nice to see [the] data on the computer screen, but what if you could feel it? Bring it to life? With our current haptic visualizer, users can feel any arbitrary surface plot generated in MATLAB as well as animate and manipulate a 3D sandbox used to draw and feel objects."

"An electric unicycle works on the same principles as a Segway but with only one wheel. When it senses that it is falling forward it moves the wheel in that direction to prevent the fall and vice versa for the other direction. Unlike a Segway, lateral balancing is the responsibility of the rider, so the prototype will have two wheels to compensate for this."

"Sound seemed to be the logical choice, and google led me to some basic circuits for triggering flashes with sound, but I wanted to be able to control the delay and sensitivity and have different modes and functions. Thanks to LMR I new the solution. Microcontroller! So I started boarding and building."

"Advancements in Javascript, node.js, have simplified communication between robot and user. Using two choice nodejs libraries, socket.io and johnny-five, you can quickly put together a system to control a robot using a web browser."
