Arduino data logger at Global Physics Department

My son presented the Arduino Data Logger he wrote for my circuits class to the Global Physics Department on 2013 May 15.  The sessions are recorded, and the recording is available on the web (though you have to run Blackboard Collaborate through Java Web Start to play the recording).

I thought he did a pretty good job of presenting the features of the data logger.

Now that school is beginning to wind down, he’s started looking at making modifications to the data logger code again, and has updated it at

He’s down to only three classes now (US History, Physics, and Dinosaur Prom Improv), though he still has homework to catch up on in Dramatic Literature and his English class.  He’s still TAing for the Python class also.

On Thursday and Friday this week, he’ll be taking the AP Computer Science test and the AP Physics C: Electricity and Magnetism test.  He’s having to take both tests in the “make-up” time slot, because we couldn’t get any local high school to agree to proctor the tests for him during the regular testing time.  Eventually his consultant teacher convinced the AP coordinator to let her proctor the tests, but by then it was too late to register for anything but the makeup tests. We’re way behind schedule on the physics class, so he’s just going to read the rest of the physics book without working any problems before Friday’s exam—we’ll finish the book in a more leisurely fashion after the exam. He won’t be as prepared for the physics exam as I had hoped, but at least the CS exam looks pretty easy to him.

One thing I didn’t realize is that schools can charge homeschoolers whatever the market will bear for proctoring the tests:

  • Depending on the reasons for late testing, schools may be charged an additional fee ($40 per exam), part or all of which the school may ask students to pay. Students eligible for the College Board fee reduction will not be charged the $40-per-exam late-testing fee, regardless of their reason for testing late.
  • Schools administering exams to homeschooled students or students from other schools may negotiate a higher fee to recover the additional proctoring and administration costs.

We’re paying $145 per exam (not just the $89 standard fee and the $40 late fee), but I’m glad he gets to take the exams at all this year.

Tomorrow he and I are doing another campus tour—this time at Stanford. He managed to get an appointment with a faculty member, but we noticed that the faculty member is scheduled to be teaching a class at the time of the appointment—I wonder what is going to happen with that. I’ll report on the visit later this week.

  1. I was really impressed with your son’s presentation. I expected him to do a good job describing the project, but it was great to hear him talk about the impact of the project on his education. He also seeded a fun conversation about the engineering analogy to the “so what is it good for” response to so many science projects.
