It's over already?

Our blogs were due two hours and 16 minutes ago, but I wanted to write a post quickly on this class as a whole.  I'm keeping it short to minimize sappiness.

I have enjoyed every moment of EXTD 160 and am amazed, looking back, at how much I've learned!  I've developed a new appreciation for engineering, and found myself beginning to see from an engineer's perspective in my other classes (particularly my exoplanet research class, ASTR 107, and my space exploration and technology class at MIT.  It's kind of strange how these three classes intertwined). I discovered new abilities in myself, such as my apparent knack for soldering, and got a good taste of electrical engineering/circuitry on which I'm looking forward to expanding in physics next semester.

It occurred to me thursday that I won't be having a class in the engineering lab next semester, and I realized that I now can't imagine a semester at Wellesley without spending ridiculous amounts of time in this lab.  As cheesy as this sounds, I feel like I've discovered a hidden jewel here at Wellesley and know I will always feel at home among the soldering irons, laser cutter and 3D printer.

Lastly, thank you Oscar for attempting to teach engineering to a bunch of non-engineers.  I hope you enjoyed working with us as much as we enjoyed learning from you!  And to my classmates, I've had a blast and I hope to see you all around in the lab next year!

Live Long and Prosper,
Hannah

Harry Potter Interactive Pop-up Adventure! (3.5.12)


From 6pm wednesday night to 5am thursday morning, Kelsey, Erin and I completely reworked our final project.  After being told our project was not interactive enough, Kelsey suggested that we create a choose-your-own-adventure (like the Goosebumps series) pop-up with six pages.  She wrote the text for each page and we sketched out a rough story-board with the circuits we wanted on each page.

Because I had the most artistic ability among us three, I was tasked with engineering the pop-ups on each page and drawing the art while Erin and Kelsey designed and soldered our circuits.  What follows is a long series of photos documenting our 11 hours in the engineering lab!  I'll start with the finished page, then a photo of the text, then close up and photos of the process to make each page.


Page 1:




We put LEDs behind three of the floating candles in the great hall.  When the reader pulls down Hedwig's tab to have her fly to Harry, she covers a photo-resistor which causes the LED's to flicker, the way Hedwig's flapping would cause candles to flicker in real life.

Pulling the tabs on the left signify using the polyjuice potion, while pulling the right tabs uses the invisibility cloak.






 Page 4:




The text is hard to read in this image.  It says:

Ron, disguided as Snape meets Malfoy in the corridor and tells him that he has failed potions.  Little did Ron know that Malfoy had just come out of the dungeon, where he had been discussing potions with the real Snape.  Malfoy notices Ron's battered shoes and recodnizes that he is a Weasley immediately.  He brushes off the comment, saying that his father will buy him a passing grade and, knowing that he is definitely up to something, stealthily follows Ron outside the castle where he meets Harry and Hermione.  Don't forget to turn off the lights, both switches, before you go to page 5.


The later it got, the cooler our circuits looked.


 At around 3am I decided we needed a comfy place to rest, so I hijacked one of the couches on the second floor of the science center (it has since been returned).  It was quite nice.

Depending on the decisions made by the reader earlier in the story, either red or green will shine from two bicolor LED's in the center of Hogwart's castle (we used the same laser cut designs from the older version of our project).

Erin made a drawing of our circuit for this page:



Depending on the color, you read one of two narrations:

I created a table that twists 90 degrees as it is opened or closed.

Also, my desk was only kinda messy by the time we hit 5am....
