Tree House

My sister and I have always wanted to build a tree house, ever since we knew what a tree house was. But we never had the time, money or know-how... until now.

A lot of kids will go out with a hammer and some nails and some 2x4's they found in the garage and try to build a tree platform... But we did some research and are doing it the right way. For instance: our big 2x10's are each fixed at one end by a single 6" lag screw (to avoid compartmentalization), and at the other end by a bracket so that the trees can sway without breaking the boards or shearing any lag screws.

Once we have these beams up in the trees, we will work on putting a deck platform on top of the foundation, but we won't get to that during break.

This has been a great final "hurrah" for the end of winter break!

Our initial scouting yielded this perfect location!

I can just see us having a picnic lunch up there next summer.

On the way home from Home Depot. The 14' one is on the roof.

Got up bright and early... for once.

I had to blaze a trail out there, because a bunch of brambles had gone rampant all over the place.

Hauling timbers.

This picture is just to show that goofy grins run in the family. (It's not just me.)

So what does all this have to do with aerospace? I dunno, maybe making friends with the rocket-eating trees is a good way to get them to leave you alone...

2011 Recapitulation

Way back in the beginning of the year I came up with three "Big, Fun Scary Adventures," referred to herein as "BFS Adventures." The first of these was a concrete goal: to obtain my level-2 certification for high-power rocketry. The story of this adventure was a long and comical one:

My first attempt was in June, using my rocket called "Stinger." I used a Cesaroni J285, which is a very small J-motor. For some reason, the flight was just a flop:



Next month I managed to put together an entirely new rocket (can't remember the name of it). It was a big, galumphing rocket made from thick cardboard tubes. The idea was to build heavy so that the rocket didn't go very high so I didn't need dual-deployment. That idea came back to bite me:



So I figured that the third time is usually the charm, and I came out next month with this rocket, which is the sustainer stage of a multistage project.



I figured that I had failed, but we kinda had to rush off at the end of the launch, and didn't talk much with the certifying member afterward. But a few weeks later I got my card in the mail, which read "cert level 2." So that's the story of how I got my level 2 certification.

My second adventure was less than exciting. I set a specific goal to "earn at least $5000 by working and at least $5000 of non-ISU scholarships." This one was also a success. I failed to find an internship, so I worked hard on a sod farm all summer, some weeks working 60 hours! It was quite the arduous ordeal but I earned about $4500 for school. Previously during the spring semester I had earned about $800 from working at Target. So there's my $5000 by working. And I got a pretty nice engineering scholarship for $8000 which helped me stay in school!

My last BFS Adventure was rather vague. "Invent something cool," I said. I'm counting the payload we built for USLI for this adventure. While it was not entirely my invention, I learned a lot of great stuff from being on that team and helped develop pretty cool technology for it. All of the structural components were designed and built by me. A lot of the programming was me, too. One thing is irrefutable: It was cool.

So there's 2011 in a nutshell. Of course, that leaves out 99% of my life, but now you have the 1% worth talking about.

I sense 2012 has some adventures in store that will make 2011 look like a walk in the park. Bring it on!

December Rockets

After a great semester, I now have three whole weeks of holiday to kill. I've already dived into a couple rocket projects, one that I've been working on for a while now, and one that I've been wanting to start for just as long.

The rocket that I got my level 2 certification on was actually designed to be the upper stage of a two-stage rocket. So I'm now continuing work on the booster stage. Where I left off was a messy plywood and expanding foam blob, and today I picked it up again and started working on a fiberglass layup. I figured that today might be my best chance, since it got up to 45 degrees today.

I also want to work on the 38mm minimum diameter rocket I've been planning. I might try doing the layups inside if I have to, but I don't want to fumigate the house with epoxy.

Lastly, if I have time, I might work on a scale rocket for USLI... but more on that later!

Home for the Holidays!

I have successfully finished out one full semester of college. Now it is time to go home for three whole weeks! What a satisfying feeling.

I have learned a lot. Here is a non-exhaustive list:

  • FORTRAN is a ridiculous programming language (unless you need to process massive amounts of data).
  • I have the ability to keep peace on a team.
  • Never leave detergent unattended in the laundry room.
  • Sometimes it's a good idea to correct a professor's error, sometimes it is best left alone.
  • Polar coordinates are actually easier to work with in many cases.
  • Meals are grossly overpriced at ISU.
  • Teach a parrot to say "supply and demand" and you've created an economist.
  • Though it sounds elementary: if you're stuck, get help.
  • I have a surprising tolerance for noise and rowdiness (that's new).
  • Sometimes you need gc in your calculations, sometimes you don't.
  • If you open the door and face a wall of wrapping paper, don't just charge through.
  • The best time for quiet thinking is 6:30-7:00 in the morning.
  • To stay on top of things in a hard class, read ahead.
  • All about partial derivatives, multiple integrals and vector calculus.
  • All about ... chemistry.
  • A lot about the love of God.

    Merry Christmas!

    This season makes me so happy and joyful inside; to celebrate the coming of the Savior and King of the Universe! Jesus is at the center of everything, and He's the center of every area and ambition in my life. I aspire to the skies because he is so cool. I learn math and science to marvel about him. Jesus is the reason for everything! Not just for the "season!"

    Merry Christmas from DTH Rocket Endeavors!
