Abstract: We have developed a mechatronic system to solve the famous Tower of Hanoi problem as part of a Carnegie Mellon University class. This class seeks solutions which solve the problem in under three minutes for the four disk case, using only the number of disks, source peg, and destination peg as user inputs. Our […]

*** Check out my blog for updated version of this project and more! *** My obsession of LEDs has led me to this. Aurora 9×18 is a thing of beauty (if I can say so myself) – has 162 RGB-LEDs in a circular configuration. The color of each circle is controlled by a microcontroller using […]

How to Build a Control Circuit with Adjustable Working Time via Wi-Fi In this article, you’ll learn how to build a system that can turn DC loads on and off using a mobile application. You’ll also learn how to perform this task via immediate actions or via timers set in advance for switching loads on […]

Love it or hate it, there’s no question that Apple’s iPhone line is popular, and while the numbers haven’t officially been announced yet, the company has already broken its record for pre-orders online (roughly 4 million in a 24-hour period compared to the iPhone 5’s 2 million). The new smartphone comes in two flavors — […]

A team of University Wisconsin-Madison researchers, with support from the Defense Advanced Research Projects Agency’s (DARPA’s) Reliable Neural-Interface Technology (RE-NET) program, have developed “invisible” implantable medical sensor arrays that will not block views of brain activity. Their research was published in the Oct. 20 issue of Nature Communications. According to a recent Phys.org article, “electrical […]

Required Hardware In order to program and debug a PIC microcontroller, you will need a few pieces of hardware. ICD-U40 The ICD-U40 is an In-Circuit-Debugger/Programmer that allows the user, through CCS C Windows IDE, to program and interactively debug a PIC microcontroller. 5V DC Power Supply Although the 4520 board has a voltage regulator that […]

This is my first instructable, so I hope everything is clear and hoping you find it interesting, and would appreciate any feedback, so here I go. I am sill testing this device with other people,  but  personally I have found  my dream recall has improved dramatically, wow! some of the dreams are totally amazing. WARNING. Because […]
