Raffael Herrmann from en.code-bude.net stuffed the guts of his RadioduinoWRT project into an old piece of stereo equipment. Inside the box he has about $100 worth of electronics including a WRT router, an Arduino Mega and an ethernet module. The result is a great looking component that can stream internet radio without having to keep a computer running to play it. “Once the basic idea to build a web
Not that this is going to be replacing a real CNC machine any time soon but this LEGO CNC Lathe shows the cool capabilities of the LEGO system. It sure is nothing like the LEGO that I grew up with that had an optional motor and wheels to allow your creations to move about.

Mjlorton gives us a lesson on Energy Storage and Density. This will be of interest to anyone who makes projects that run from batteries.
If you have a project that needs some cooling you might want to look into using a Peltier Module. RimstarOrg found one in an old water cooler, with a bit of disassemble he found a system that consisted of a 12 volt transformer which feeds a small board which coverts it to 12 volts DC that the module needs and finally there is a small circuit which measures that
Ben Krasnow wanted to use a cheap digital scale to use in a project that needs to automatically dispense the correct amount of material and stop when the appropriate weight has been achieved. We have seen this type of system used in factories that bag things by weight such as potato chips. These small scales use a strain gauge to read how much weight is on the scale. The
