## 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.

## Math Practice – #2

Number Theorey?, Pure Math?, Charles Babbage GIVEN: At Charles Babbage’s Wedding (fictional) the tables are labeled ‘A’ to ‘Z’. Each of the center pieces is an arrangement of golden spheres. These golden spheres are arranged on the tables as follows: FIND: How many golden spheres are there on Table ‘F’? […]

## Math Practice – #1

Flow, Related Rates, Geometry, Caclulus, Control Volumes, Volume, Rate, Unit Conversions GIVEN: A rectangular tub is being filled with the drain open. PROBLEM: The tub begins empty. More water is entering the tub than draining from it. If 1 gallon/minute is flowing into the tub, and 0.5 gallons/minute are flowing […]

## Senior Design Project (prototype 3.0) – the final prototype

For those of you who missed the first installment of this post, see: Project prototype 2.5 After completing the construction and testing of the “second prototype” (2.5), it was time to design, fabricate, and test the final prototype. Here are a few pictures of the final design: and a progression […]

## Labview Proportional Control Code Example

The following are a few highlights of a simple control system built this spring. As can be seen in the picture, a power source was used in conjunction with a LabVIEW DAQ and a thermocouple module with a digial output module (for pwm for the fan). A computer fan and […]

## 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 […]
