New Years celebrations tend to get bigger and bigger every year for most people, and [Brian] takes no exception. In order to top his lighted tree of a few years ago, he has concocted a 40′x40′ set of Seven-Segment displays made out of Christmas lights, hung from nearby trees. These displays would start counting down [...]

Singing: With Plasma!

Posted: December 28th, 2010, 9:49am MST by James Munns

While there are many ways to produce audible sound, Plasma Speakers have to be one of the coolest. Usually very complex and expensive, we received a tip for a beginners guide to making one of these impressive novelties. Handily included are a set of schematics (one very simple schematic, the other with a few artistic illustrations). There [...]

Pulito: The LEGO Roomba

Posted: November 14th, 2010, 9:00am MST by James Munns

brickAVR: the Proto-brick

Posted: December 15th, 2009, 8:41am MST by James Munns

Sometimes, prototyping systems need to be robust, full-featured, and powerful. Other times, nostalgia and simplicity are much more appealing. Rather than buying a pre-made prototyping board, one of our readers grabbed some parts lying around, including an Atmega8, a SMD 16Mhz oscillator, and a 6 pin ISP header, and performed some circuit origami free-form soldering (thanks [...]
