INTRO TO ENGINEERING CLASS PROJECTS
[2015-16]
Bridge Project
In this video, we test our bridge made of popsicle sticks, rubber bands, skewers, glue, and fishing line. It has a truss and suspension (fishing line running underneath and supporting the bridge) design. In the end, the bridge did not collapse but bent so much that the bucket touched the ground and we had to stop.

Pasta Tower Project
This video shows our group testing our fractal inspired pasta tower. Although it was made only out of pasta and glue, we were able to fill the bucket with up to 25kg of sand, before the tower collapsed.

Logic Gates
"The most inefficient way to power an LED." I made a needlessly complex chain of logic gates (AND, NOT, OR) in order to power the LED. You can see a video of the circuit in action.

Logic Gates (MIT Edition)
"The logical way to power an LED." After messing around with the logic gates, I decided to try and spell out MIT with them before powering the LED. You can see the result in the photo.
Multi-color Diode
Here is a video of a basic circuit we created that uses buttons to control a multi-color diode. The red button turns on the red LED, the green the green, and the blue the blue. By holding down multiple buttons, we can create mixed colors.

LCD Rocket Countdown
Here is a video of an LCD I wired to a Sparkfun Redboard and programmed it to countdown from 10 to "LIFT OFF." It then begins counting down all over again. The potentiometer could be used to adjust screen brightness/contrast.

Rheostat Board
Here is a video of a circuit we created that used a potentiometer (rheostat usage) and button to control the brightness of an LED. By turning the potentiometer we were able to brighten and dim the LED. By pressing the button, we set the LED to max brightness, regardless of previous brightness.
