A power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
Every power supply must obtain the energy it supplies to its load, as well as any energy it consumes while performing that task, from an energy source. Depending on its design, a power supply may obtain energy from various types of energy sources, including electrical energy transmission systems, energy storage devices such as a batteries and fuel cells, electromechanical systems such as generators and alternators, solar power converters, or another power supply.
All power supplies have a power input, which receives energy from the energy source, and a power output that delivers energy to the load. In most power supplies the power input and output consist of electrical connectors or hardwired circuit connections, though some power supplies employ wireless energy transfer in lieu of galvanic connections for the power input or output. Some power supplies have other types of inputs and outputs as well, for functions such as external monitoring and control.

Do it yourself, also known as DIY, is the method of building, modifying, or repairing something without the direct aid of experts or professionals. Academic research describes DIY as behaviors where "individuals engage raw and semi-raw materials and component parts to produce, transform, or reconstruct material possessions, including those drawn from the natural environment (e.g. landscaping)". DIY behavior can be triggered by various motivations previously categorized as marketplace motivations (economic benefits, lack of product availability, lack of product quality, need for customization), and identity enhancement (craftsmanship, empowerment, community seeking, uniqueness)
The term "do-it-yourself" has been associated with consumers since at least 1912 primarily in the domain of home improvement and maintenance activities. The phrase "do it yourself" had come into common usage (in standard English) by the 1950s, in reference to the emergence of a trend of people undertaking home improvement and various other small craft and construction projects as both a creative-recreational and cost-saving activity.

Here's a very in-depth and honest look at CyberPower Systems' GX1325U sine wave uninterruptible power supply. It's the model to buy if you need such a thing, but there isn't much competition. The good: 1. Yes, it really has a true sine wave output. And that output *stays* clean even under heavy, highly inductive loads. I didn't expect it to do nearly as well as it did! 2. It passed my brutal "furnace fan" test and kept a Power Macintosh G5's very picky power supply happy. 3. It has a serial port, though presumably only for simple signaling. 4. You can use it to provide a power backup for almost anything that plugs into an outlet, so long as you don't exceed the ratings. 5. Pricing is very competitive with other UPSes having only a "stepped" sine wave output. 6. It's basically the only UPS...

PART 2 is HERE: http://www.youtube.com/watch?v=6Otr1I0OR18 Dave shows you how to design a simple constant current and constant voltage lab power supply that can be either software (PIC/AVR et.al microcontroller) or traditional pot controlled. Starting with the venerable LM317, and ending up with an LT3080 solution, and the some thought processes that go into it all. Part 1 is the conceptual design of this Open Hardware design.

I kept the "preliminary fuse" of 315mA for the primary but settled on a larger 1.5A fuse for the 5V because 1A is underpowered (and causes problems, especially on the VIC20 which is a bit more power hungry).
