The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.

Any book on basic operational amplifier (aka "op amp") circuits would be a good idea, they're actually very easy to use in simple circuits, inexpensive, and you'll find they have a 1001 uses.
Get two or three cheap DC power supplies, and an inexpensive handheld digital meter. Later on, consider an oscilloscope. It's a big expense item, but is worth it's weight in gold when designing, building, and debugging dynamic circuits.
Also get one or more of those plug-in prototyping strips so you can quickly build up, modify, and tear down circuits.

I've already got those! I'm going to look for the "Art of Electronics" book. It seems everyone all over the internet loves it. I even had my chemistry professor recommend it.

My best recommendation to you is to find some small circuits "Turkey9" recommended. Find something that you can actually use, something fun, or something that someone you know can use. I started my first project as a small LM386 guitar amp. Then I moved to a small IC 4093 based soil moisture meter for my mom. Right now I am working on a power supply for my work bench, a small Tesla coil, a ZVS flyback driver, and rewinding a microwave oven transformer for a variable AC supply. There are several good websites out there with schematics for simple projects. I like myself. Here are a few good links that I have used.
BTW if you use allaboutcircuits keep in mind that they are a bit snooty when it comes to high voltage.

How so?
This IS a unique hobby. Some Ham operators get into it but it's sort of an "island" in electronic issues. Did they offer advice NOT to get involved in HV oriented things (Tesla Coils, etc)???
Power supplies THEMSELVES are a great project....They can range from very simple to quite challenging.

I tried to post a question looking for help on my zvs driver. They closed the post and said "we do not allow this kind of circuit here because they are dangerous". So I posted my question here on 4hv.org. Here is a link.

If statistically, more individuals are lethally electrocuted via common household mains, what circuit which uses that as a means to supply does not have that potential? I am surprised at their attitude. They have a great deal to offer as a starting place....

On the issue of lethal equipment consider collateral consequences. What happens when YOU are not around your setup. Family members, especially younger siblings can get into anything.
If something happened to you, what would happen to the gear when it was disposed of ? Do you really want that electronic stuff you cleverly salvaged by digging into the supply circuit and bypassing the thermal link ending up in someone's home?

Many manufacturers of semiconductor components publish application notes, to give designers a leg-up in using them. Also data sheets frequently have application circuits in them. Try Analog Devices, Linear Technology, National Semiconductor, Maxim, Texas Instruments for a start

The example, while bearing some accuracy, can have transposition to most anything from mousetraps to chemicals. The web site certainly has the right to limit it's offerings but does not the individual bear similar responsibility in the handling of any object with the potential to do harm?
I earnestly believe that protecting people from themselves is an impossibility. With children however, I cannot dispute that the adult has every responsibility to keep them from such situations. However, mature individuals must bear their own responsibility to the consequences or we will find a world where law suits prevail over the homeowner who is bested by the burglar when he gets stuck in the hole in the roof....
So we reach a crossroads where a web site that offers material that demands a level of intellect to understand - disputes that intellect when it comes to self preservation (or in our case; the protection of the family).
