In Which I Am Frowned Upon by German Society For My Poor Choice in Footwear

Let me preface this post by pointing out that as of today in Berlin, it is bone-chillingly cold. The last few days have been positively spring-like, but last night took a turn for the worse and snow has been coming down in flurries every few minutes. As of now, snow covers the ground and everything on it, and it doesn’t show signs of stopping.

Since I arrived I have been taking note of many cultural differences between Germany and the US, but I haven’t experienced them firsthand until today. I brought with me two pairs of Embassy-appropriate shoes, and chose to wear the more sensible of the two, a black pair of loafers which unfortunately exposed the top half of my foot. I saw nothing wrong with this, except for the knowledge that my feet would be a little uncomfortable during my walk from the apartment to the train, then from the train to the embassy and back again that afternoon.

Packing and Wondering: my experience the night before we leave for Liberia

As I sit here in my family room, I continue to pack tirelessly with my father and 14 year-old brother who has slipped away, probably to relish his last moments of solitude, internet access and “comfort”. The room is now a maze of clothing piles, medicine, ointments, as well as a lot of anti-diarrheals and bug repellent. One of the many challenges this trip poses is that everything my family has decided to bring must travel with us to Goyazu; a day’s walk in the forest. This means we will have to hire strong men to help us carry our load. Along with our clothing and toiletries, we are bringing notebooks, textbooks, pencils and other supply for the school to use. We have decided that most of the clothes and things we bring will stay in Goyazu for our family. Continue reading “Packing and Wondering: my experience the night before we leave for Liberia”

Hello from a whole new world…

Thursday, March 7, 2013.

Hi everyone, my name is Claudia. I was out of the country for the two weeks before Senior Projects, so I never made an intro post. I am living at home and working with the Latin American Community Center in Wilmington, DE for my Senior Project. I went in offering to do whatever they needed me to do and I ended up assigned to one of their Family Resource Coordinators. I have been helping her with whatever she needs me to do with managing her clients.

The work is totally different from anything I have done before. The actual tasks are, for the most part, simple. I do a lot of photocopying and file reviewing. The context, however, is totally alien. Westtown exists in a bubble of privilege. It doesn’t matter where you come from originally; when you arrive at the school you are one of the privileged few. We are incredibly lucky to have that opportunity, but given that I come from a stable nuclear family with enough money to live comfortably, I had never really seen what that meant. Poverty and unemployment are hot topics in the current economic situation, but news coverage is an abstract. People living below the poverty line, people who live hand to mouth, people who wonder how they’re going to make rent next month. Such people have never been a concrete reality for me, until now. Continue reading “Hello from a whole new world…”

 

Like a child on her first day of school, my aunt walked me up to the formidable grey building. The slick stone wall is engraved with the words ‘EMBASSY TO THE UNITED STATES OF AMERICA’. There is a length of velvet roping sectioning off a clearly marked pathway to the door. Standing between me and the door is a severe looking security guard. He glared and watched as we approached. His arms were crossed over his broad chest. 

“Identification.”

I handed over my passport, and looked up at him nervously. I felt like a kid trying to get past a bouncer. He nodded, and muttered something into a walkie talkie. I entered trough the thick doors as tourists walking past stared. I was led to another security guard, who stared me down with a similar glare. 

“Electronics.”

I handed over my cell phone, iPod, and my headphones. He put them in a special cubby. I would get them back when I was ready to leave. My first-world brain panicked for a second. What would I do without my phone? 

Wanting to kick myself, I walked through a metal detector and over to a big window, behind which sat a Marine in full uniform. He stared at me through the glass. I smiled weakly and slid my passport under a slot in the window. He slid back a red pass reading ‘Visitor. Escort Required.’ 

I was given a tour of the building, as well as taken through the different floors meeting people. I shook hands and introduced myself. The more people I met the more I was struck by how everyone working in the Embassy had such a wide variety of skill sets and backgrounds, the incredible breadth of education being used. If you were a math major, you could find work at the Embassy. If you were a foreign language major, there was a place for you. Communications, Sociology, Political Science, Management, Media Science, Journalism, everything under the sun was represented in the people I came in contact with. 

In the afternoon I took an art tour of the Embassy with some of the other interns. The Embassy is chockfull of exciting art, including a piece by Andy Warhol dusted with diamond dust, and four Jackson Pollocks. This was not something I had expected, and it seemed to me to be a little bit of a shame that these incredible works of art were there in the building but only for those who could get past security to see. 

I ended my day with an interesting and informative WMD (Weapons of Mass Destruction) presentation. This presentation went over what we should do in the case of an attack using WMDs. This does not mean bombs or guns; the building is well equipped to deal with those, but rather in the event of specialized biological attacks. Mustard gas or anthrax, for example. Working in such a high-risk environment puts you in a potentially dangerous situation, or rather as the presenter put it; as soon as you put an American flag on a building, you may as well be painting a big target on the side of that building. 

After learning how to use the nerve agent neutralizer syringes, I appreciated the surly security guards a little more. After all, they had everyone in the building’s best interests at heart. When I left for the day to take the S-Bahn back to the apartment, I grinned at the guard standing outside and told him to have a good night. He nodded back at me and glared.

TourBot 3: More Stuff Gets Built…

If this is you’re first time reading about TourBot please read post #1 and post #2 otherwise this post won’t make a whole lot of sense

With the arm completed, today’s mission was to make the drivebase. (the frame and wheels)

drivebase

Now, anyone who follows my previous posts will probably remember in my first post there was a picture of two TourBot designs that were almost the same, but how the wheels were mounted was different. That was becasue deep down inside I harbored the hope that we would have enough money to pay to have the pieces water jetted. But the budget wasn’t big enough for that so….

WP_20130306_006
notice how I’m standing on scrap aluminum becasue I’m too short…

I went to work with the angle grinder….

WP_20130306_008

and cut out four rectangles in two 18″ long pieces of 2 1/2″x1 1/2″ box aluminum

WP_20130306_016

drilled and tapped the mounting holes…

cut the other frame pieces, assembled them, added wheels

WP_20130306_039
and (once again) through the magic of me forgetting to take pictures we ended up with this…

Things left to do

  • mount the motors and chain
  • make/mount the top and bottom plates
  • mount the arm on the drivebase
  • add electronics
  • wire it
  • paint it
  • make Ben program it

It should be driveable by tomorrow

TourBot 2: Stuff gets Built…

tb

Last time I posted about TourBot it looked like this.  Which is cool, except for one slight problem. It only exists on my computer. Today’s goal was to change that…

So I did the only sensible thing and started assembling the motors/gearboxes. (a part I won’t need until about 1/2 the way through the build.)

WP_20130305_001

The three gearboxes and motors that will be used in TourBot before assembly.

WP_20130305_005

The first step after getting everything out of the packaging was putting the pinion on the motor’s shaft. Which is easier said than done because the pinion’s hole is about .002″ smaller than the shaft’s diameter. This means that once its on the shaft it isn’t coming off or slipping. However it makes it pretty much impossible to put the pinion on the shaft without an arbor press. I do not own an arbor press.

WP_20130305_019

I had to improvise with my drill press. Because drill press and arbor press are close enough, right? I mean they both have the word “press” in their name.

WP_20130305_020
tweezers made this so much easier

After getting the pinions on the motors I then greased the gearboxes. This was another one of those easier said than done things. To grease a gearbox you need to take it apart and remove all the gears and squirt grease in between each layer of gears.  Because the gearboxes are high reduction (64:1) planetary gearboxes, there are a lot of gears in them. Fifteen to be exact and in order to reassemble the gearboxes they all had to be perfectly aligned to the ring gear for it to fit.

WP_20130305_022

After repeating this process two more times, I had three gearboxes done and moved on to building the arm.

el_arm_o

I started by taking all the measurements from my CAD drawing, and then cutting out the pieces from my tube steel collection.

I began by making the moving parts of the arm. This involved welding a 25″ long square piece of tube to a round piece to make a T shape.

WP_20130305_029

I then made another one and cut the steel to mount them…

WP_20130305_035

and then test fitted everything…

WP_20130305_037

and welded more…

forgot to take pictures…

WP_20130305_043
you have no idea how hard it was to balance it so it stood up for the picture…

and ended with the arm done, sans paint.

A Short Bit In Which I Describe My Lufthansa Experience

“I’m a firefighter, if that makes you feel any better.” boasts the man sitting next to me, in response to my reluctant admission to being what they call a ‘nervous flyer’. Joe from Jersey, the firefighter, spends the next seven hours alternating between assuring me that he ‘never flies economy class’ (I’m sorry sir, but according to your seat assignment, you do in fact fly economy class just like the rest of us peasants), and snoring loudly. I made the mistake of telling him I spoke no German, to which he gleefully delegated himself the task of teaching me everything he knew. Nein, danke. 

I learned a lot more about Joe during that flight than I ever wanted to know, and quickly realized with a sinking heart that overnight flight meant I could not pointedly look out the window the entire time, too engrossed in nature’s beauty to listen to stories about his Slovakian girlfriend he was going to visit. As the maraschino cherry on top of the double-fudge milkshake brownie sundae, Joe gave me a parting gift as we exited the plane. It was a pocket sized cartoon pamphlet entitled ‘Where Will You Spend Eternity?”
