In this project I am going to show you how to make a joule thief and put it in a jar. This joule thief is a simple circuit that will take an old “dead” AA or AAA battery and up the voltage enough to power an LED. I use these as decorations and to completely drain batteries that are too “dead” to work in other devices. Note: The only unique idea here is to stick one of these circuits into a plastic jar. The circuit is not mine. Read on…

Once upon a time I had a 2.5 gallon nano reef tank and I wanted to add a refugium to it to grow macro algae. Being such a small tank it did not make sense to set up a smaller tank to act as a refugium like some people do for larger reef tanks. So, I came up with the idea of adding a refugium to the small power filter that provided water movement to the tank. Read on…

Several years ago I needed to replace the ballast for the compact fluorescent bulb on a 13 gallon Nano Cube aquarium. Looking around for replacement ballasts I discovered that they were quite expensive. I had the idea to try to use the ballast from one of those screw-in fluorescent bulbs. Well, It worked and since then, I have used this same process to power other compact and normal fluorescent bulbs. Read on…
