Material for a UC Irvine course offered by the Department of Physics Astronomy and developed by David Kirkby.
This course uses a standard component kit for each student whose total cost is about US$200 and fits comfortably in a 6-quart plastic storage box, weighing about 365g (less than a pound).
Many of the components are designed and manufactured by adafruit which provides excellent supporting documentation and tutorials.
For basic examples that demonstrate each of the kit’s components, start here.
