We’ve all seen the neat projects on the web where someone uses a power supply taken from an old PC. There is something simple about the project, yet so insanely useful and versatile.
I have not seen many that were as “polished” as the power supply project here. This is from the blog “TG’s Electronics Exploration”. The project is laid out in a way that will give you multiple power options as well as a digital readout. Most of the power supply projects I’ve seen are relatively simple hacks where the basic simple values of a PC power supply are used (5 volts, 12 volts, etc). This has many more options.
I really like how clean the layout is as well as the LCD’s. The other really neat thing about his – the work isn’t wasted if the power supply eventually dies on you. It is relatively easy to move all the electronics to a new supply.

The next website we will talk about comes from a sit I visit on a regular basis. Not ham radio, but plenty of electronics information and kits – ladyada.net. I used to run a hackerspace in my area. We did a few projects to get people soldering. One neat project was a “TV be-gone”. Simple device where you build it, put it in a container (I, of course, used an Altoids tin) and use it to turn off TV’s. Great when you’re somewhere where a TV is on, loud, and nobody is actually watching the thing and you can’t even carry a conversation with the guy next to you. Simple enough project.
This site goes into several questions I get from potential hams when I teach radio classes, including:
What is a power supply?
Why use a power supply?
What’s inside a power supply?
A really neat primer geared towards those that may not understand anything about all those wall warts that are drawing tons of power when not used! I almost passed this up, as I know enough about power supplies to get me through what I need for my projects. I found it a neat article that allowed me to probably explain it easier to those that aren’t technically inclined.
