Every electronics lab needs a couple different types of voltage sources. Power supplies are the obvious choice, but these bench top supplies are not very stable over time and temperature, they cannot sink current and it can be very difficult to set an accurate voltage. This video gives a step-by-step demonstration of an amplifier and precision reference based circuit design for a relatively inexpensive precision voltage source.
