|Multimeter reading 4.91 volts -- close enough to 5V for me to be happy.|
My 5VDC regulated power supply is now working... but it doesn't look exactly like the one in Figure S-2. First, I didn't have a 0.33 microfarad capacitor. (Actually, I probably do, but sometime in the past my nice organized capacitor collection became disorganized. I'm not going to point fingers at either the 7 or 4 year old boys in my household, but I'm certainly looking in their direction.)

As with Figure S-2, I added in a green LED but the more I think about it a red LED is more likely to make someone think *DANGER* so I'll swap that out later. I had plenty of 2.2k resistors in my collection as well.

I'm not using a 9V battery. Instead, I pulled out the variable wall wart I purchased back when I was working through Make: Electronics. The ends are stripped and I soldered on a piece of red wire and black wire and added some shrink wrap to identify the leads. Those go into the breadboard as shown in Figure S-1 and after double-checking my wiring... I flipped the little power switch. The LED began to glow and no smoke was seen coming from either capacitor. (Remember: if you're using capacitors that actually have polarity, wire them up the right way -- the black stripe on the side goes towards GND.)
Here's the video describing my setup:

My next tasks are transferring this wiring to a new breadboard (or two) to test the continuity of the power and GND lines as well as the ability to easily insert wires and components PLUS testing out Experiment 1.
