Build a uA723 50th anniversary circuit
Here is a nice project using a classic chip from the past: the good old voltage regulator uA723. According to Wikipedia this chip was designed by Bob "every-idiot-can-count-to-one" Widlar and commercialised by Fairchild Semiconductor in 1967. Now, 50 years later, we encounter this chip in its metal-can version in a digitally controlled current source, showing that if, like the Rolling Stones, you feature excellent input and load regulation, you can have a long career under the spotlights.

Imagine you want to measure soil temperature. For ease of use and precision an electronic thermometer with an easily readable display would be nice. The sensor must be such that it can be stuck in the dirt, dry or humid, and while you’re at it, what about being able to measure the temperature of a roast on the BBQ? Enter the Resistance Temperature Detector or RTD together with a precision resistance meter.
