Building the Electrical Current Model with The Amazing $25 Programmable Power Supply

Not Just For Teaching Robotics Thanks to the generous donations of supporters of the Physics Academy, we were able to purchase a new set of Arduino Uno micro-controllers for use in this year’s robotics competition. As I was planning out the unit on teaching DC circuits, I realized that some of our DC power suppliesContinue reading “Building the Electrical Current Model with The Amazing $25 Programmable Power Supply”

A Modernized Bridge Design Contest

Modernizing An Old Classic We have just completed the second project in the Academy for the 2014-15 school year. It was a huge success! This project takes a classic physics project and “upgrades” it by incorporating modern engineering design technology and fabrication techniques. We started with a great project that is now available online throughContinue reading “A Modernized Bridge Design Contest”

Modeling A Rocket’s Journey – A Synthesis

A Synthesis Of All The Models (Thus Far) In this post I will describe a culminating activity for the first year students in the Academy. This is really the destination that the students have been headed towards since the beginning of the course. Everything they have learned is synthesized in this activity where the studentsContinue reading “Modeling A Rocket’s Journey – A Synthesis”

Testing Motors For The Solar Dragster Race

Torque/Speed Curves In this post I’m going to describe our attempt to measure the power curve for the DC motors used in the Solar Dragster race this year. I’m going to be honest, our efforts weren’t really that successful, but I can at least say that I learned some things that might help for nextContinue reading “Testing Motors For The Solar Dragster Race”

Our New Full Spectrum Laser

Last week our new Full Spectrum Laser arrived at school. Thanks to the generous donation of a graduating senior’s parents, we were able to purchase theĀ Full Spectrum Pro LF Series 36×24 model with a 90 W laser upgrade and active water chiller. This cutter replaces our eight year old laser that has had some seriousContinue reading “Our New Full Spectrum Laser”
