The Completely Hackable Amateur Radio Telescope (CHART) Project
Lindsay M. Berkhout, Adam P. Beardsley, Daniel C. Jacobs +4
We present the Completely Hackable Amateur Radio Telescope (CHART), a project that provides hands-on radio instrumentation and design experience to undergraduates while bringing ac…
Finger Paint and Physics: A simple demonstration of Circular Motion and Conservation of Energy
Sarah Phan-Budd
It can be a challenge to come up with simple demonstrations of circular motion and conservation of energy. One such demonstration consists of a large exercise ball, off of which a…
Notes on pulse-width modulation appropriate for a sophomore-level electronics or programming class
Nathan T Moore
Pulse-width modulation is a nice way to create pseudo analog outputs from a microcontroller (eg, an Arduino), which is limited to digital output signals. The quality of the analog…
Small Oscillations via Conservation of Energy in a Simple Static Equilibrium Problem
Tia Troy, Megan Reiner, Andrew Haugen +1
The work describes an analogy-based small oscillations analysis of a standard static equilibrium lab problem. In addition to force analysis, a potential energy function for the sys…
Building Thinking Skills in Pre-service Elementary School Teachers
Nathan Moore, Jacqueline O'Donnell
The work describes curricular modification to a physical science content class for elementary education majors at Winona State University. The modification, the regular use of Cogn…
