Lots of others on this home engineering lab. I'm jealous, he has a lot more test equipment then me🙂
That was just one video but here is the main site:

Take a look at his video blog #1, reviews a book by Woz and a voltage regulator that can output all the way to zero volts, something I had to design for a thermocouple calibrator, mine needed exactly 8 millivolts at around 200 ohms impedance. My design worked but it needed a lot more parts than this chip the LT3085.
