Solar Eclipse: May 20, 2012

Today was an annular solar eclipse.  We didn't get a very good view, as the sun was setting during the eclipse.  However, I brought the family out to the college, which has a good view of the western horizon.  The physics teacher at the college pulled into the parking lot half an hour after we did, with the exact same idea.  Here are the pictures I got.

This is a projection of the Sun through my telescope.  The green circles indicate sun spots.

A close up of my viewing set-up.  You can see the Sun and my son.

This was as much of the eclipse that I could see on the cardboard.  The setting Sun grew too dim to see after this.


The setting Sun was dim enough to allow for direct photographs to be taken.  This is one of the best shots that I got.

Speed Bot

Speed Bot 1.1 with remote
I built this simple robot to bring to a middle school science class on Tuesday.  It was meant to help the students understand the effect of changing the wheel size on the speed of the robot.  Unfortunately, I didn't get to finish the robot for the class time.  That didn't work out to be a problem because the class was broken into small groups, and one group worked on finishing this robot.

The problem that the students had with this robot is that the radio control didn't work.  After a hour of researching after class, I found out that  the original VEX firmware was erased by the ROBOTC firmware, and that the robot would have to manually programmed to respond to the remote control.  The program I used can be found here.

Graduation 2012

One of the highlights of the academic year at our community college is graduation.  We're small enough that the faculty know most of the students in the ceremony.  Because we have so many first generation college students, the families of the students make a big deal out of the graduation.

Because of the weather, we had to have the ceremony indoors.  We have a small auditorium, so the graduation was held in shifts.  There were five different processions, and the families of the students filed out after each round of degree conferences.  This made for a longer ceremony, but it was much more comfortable for the people involved.  The only possible exception was the college president, who had been at the college since 6:00am.  The draw back for me is that I missed the opportunity to meet the families of a couple of my students.  I was hoping to brag about Carlos to his family.

There is already an article on the graduation on the local paper's website.  You can read it here.  One impressive feature is that it records the graduates by county.  There are 32 counties total represented, and one student from Virginia.

For good measure, here is the best picture of a Clooney that I've yet taken.  It is of the back of Nick Clooney's head.  As a former news anchor, that's an uncommon angle to get his picture.  By all accounts, Mr. and Mrs. Clooney are very friendly people.  I just never get close enough to say "hi".
