Poetry Recital

The second grade poetry recital at Jono's school was hilarious. One after another the kids got up on stage and read a poem of their choice to a crowd of about 150 parents, teachers, and peers. Jono's poem was called "Point of View" by Shel Silverstein. I made his prop, the "turkey feathers" the night before.

Thanksgiving dinner's sad and thankless

Christmas dinner's dark and blue

When you stop and try to see it

From the turkey's point of view.

Sunday dinner isn't sunny

Easter feasts are just bad luck

When you see it from the viewpoint

Of a chicken or a duck.

Oh how I once loved tuna salad

Pork and lobsters, lamb chops too

'Til I stopped and looked at dinner

From the dinner's point of view.

Climb On

I teach a junior-level engineering class on the subject of Engineering Design with another professor, Dr. N., who is a mechanical engineer (I am an electrical engineer). Still reading? Every semester we dream up a gizmo, a thingy, or a widget that the students have to design. This semester it was a rope-climbing robot.

The robot had to start at the base of an eight-foot-long rope and climb to the top. When it encountered the "ceiling" it was to stop on its own and, if applicable, retract itself to within one foot of the ceiling. They could not use wheels to climb, they had to use a grasping motion like a climber. The video shows our testing and some spontaneous racing that occurred on test day! Their designs were great and I must say that I'm proud of them!

Austin Swimming

A couple of weekends ago our family went to Austin for a big swim meet. The University of Texas has a world-class swimming pool and the kids enjoyed themselves. This picture is from David's 100 m butterfly race.

Outside of the swimming complex is an antique oil well, the first one on the campus of a Texas college. Jono and I wandered over to take a look at it. He is naturally attracted to machines; it makes me laugh.

Not much else to say about this. Witty comments and funny stories next time...

Honduras Bound

I am leading a new team of 10 engineering students and one faculty colleague back to Honduras next week. Lord willing, we will be installing a hydro electric generator in a new orphanage called Promise Home, near El Progresso. (See http://promisehome.org/ from where I borrowed the very cool logo. The white part in the hand is in the shape of Honduras, and the five stars are in Honduran flag.)

They already have a long section of PVC pipe (called a penstock) that brings water in from the nearby river. They also have already built a power house for our generating equipment. Below you see the inside of the power house. There are three pipes coming in from the river. The one on the left is 6" in diameter, the other two are 8". For the next year or two, we will only use the smaller one. After the water flows through the generator, it exits the power house via the concrete "bathtub" in the floor. There are two large drain pipes there that bring the water back to the river, downstream from our inlet.

This is the outside of the power house. You can see the 6" pipe running off to the river. The last image is a model of our "Pelton Runner" which is the water wheel gizmo that serves as the interface between our generator and the actual jets of water. Lance did a good job on this.

More posts about our trip coming soon!

Return to the Blogosphere!

Hello people! The rumors that I no longer blog but only Twitter and update my Facebook page are vicious lies from those bent on discrediting the fine name of Orangehouse. You may be wondering where I have been. More likely, you haven't noticed that I have been gone. More likely still, no one is ever going to read this. I can only say that I have been busy and that when I do sit down to write, I end up staring at the blank page and thinking about all the things I should be doing...

Here's a story about our family trip to Cameron Park last weekend. We played soccer and baseball and David and I rode our bikes on some of the trails that run beside the confluence of the Bosque and Brazos rivers. We have been talking about doing this for a year or so, and last weekend the weather was perfect. As we rode on the beautiful trail we noticed the river level was up from the recent rains. After about two miles, the trail dipped down and was covered by a swollen inlet from the river.

It didn't look very deep, so I suggested that David ride across first to test the waters. He easily powered across the inlet; the water was only about a foot deep. He got his shoes a little wet, but had no problem getting across. After reaching the other side he saw a sign that warned of falling rocks. Since I didn't really want to get my feet wet, I called him back across the inlet. "Let's go back" I said, as I started to pull my phone/camera.

Suddenly, his entire front tire plunged into the water and he flew over the handlebars into the river!

The above photo is about two seconds after he went in head first. He scrambled out of the water and left his bike. You can see the back tire sticking up in the next picture. It looks like a floating log or a piece of debris.
So it turns out the inlet was deeper than we thought. Soon we deduced that the first time David rode across (without a problem) HE RODE ON A SUBMERGED BRIDGE! Coming back across he wasn't so lucky and rode off the side of the bridge. Surprise!

Happy for the adventure, and soaking wet, I made him pose for another picture where the two rivers meet. Hoop dee doo.
