This spring, we’ve had the honor to help judge the 555 Contest organized by Jeri Ellsworth and Chris Gammell.
Now that the scores have been received from final-round celebrity judges Hans Camenzind and Forrest Mims, Jeri and Chris will be announcing the results of the contest live on uStream, today (Wednesday April 20) at 9 pm EST.To help get you in the mood for the results, here are just a few of our favorites that you may not have seen, in no particular order– hopefully some of these will be amongst the winners!

Rather brilliant 555-based POV display by Michael Noland, writes out “555” in space, using nothing but 555s:
This Atari Punk Sequencer just rocks; check out the video.
Pavel Hanak built the most pure 555 circuits that we’ve ever seen: Astable Multivibrators Built Solely From 555s. No external resistors or capacitors, just the internal resistance and capacitance of up to 20 additional 555s. (Clearly an insane genius!)
