What is it? It is a decorative lamp; a very, very impractical decorative lamp employing a few vintage display devices and a couple of LEDs too. A friend of mine was one of a group of artists who produced Ascension (the giant origami-crane tent) at the 2010 Coachella Music and Arts Festival. Since he was

The ZIFduino, for all intents and purposes, is an Arduino with a ZIF socket. It’s geared toward those that want to do prototyping on the platform, but then move the ATMega chip to a stand-alone environment. The pin layouts are exactly the same, so it should be compatible with most shields designed for the Arduino.
