Composite vs S-video vs Component

Component CablesI’ve heard that component cables provide higher picture quality than s-video and composite cables but I wanted to find out if this was true and if so, to what extent.  I tried all 3 cable types on a DVD player, Wii, and PS2.  The cables fed into a 32″ LCD HDTV.  I played the same test image on all 3 devices.  I photographed the TV screen with a digital camera on a tripod with a timer so that there would be no shake.  Read on…

Joule Thief in a Jar

jar_onIn 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.
