Add Some Randomness to Your (WordPress) Website

Every time you refresh the page, this picture of the book(s) will change:   Install a wordpress Plugin called (PHP Code for Posts) Then, write a simple program which randomly generates a number, then displays a certain line of code (for a picture) into the spot where you want you […]

Data and Information Visualization Part II

Sometimes it is important to create your own figures when they don’t exist. (see Data and Information Visualization Part I) The example I’d like to give is from a paper titled “Thermal Performance of Domestic Replacement A19 LED Lighting Products.” The paper highlights the varied nature of LED heat sink […]

Print a Pi Day

Happy Pi day. You can download the 3D files at Thingverse! Then find a 3D printer, print one, and send it to someone you love! P.S. This “pi pie” should fit in the palm of your hand.

Simplicity in Design

Simplicity is an essential property of good design. It saves time, money, resources, and is easier to understand and analyze.

Senior Design Project (prototype 2.5)

Mechanical engineering students are required to complete a senior design project. What follows are a few highlights of our group’s progress so far. For a site devoted to the project, visit: Bike Brake WordPress Our project was to replace a traditional bicycle brake with a device which would slow the […]

Arduino Regenerative Bike Brake Code

Arduino Code The following is a prototype program for a device used on a bicycle with a generator for a brake.  Essentially this is a regenerative brake for a bicycle which charges a USB battery (one of the new mobile charger batteries).  Thus, when you’re braking, you can charge this […]
