NE555+LED Contest (inofficial)
I added a small contest to my contribution for the Instructables Advent Calendar 2011. Go for it and make your own NE555+LED-Circuit OR an LED-circuit with other components. Share your circuit in the comments of the I'ble to win a 1-year Pro-Membership. Only restriction: It has to fit on a mini breadboard, so it fits into the altoids tin.
Have fun and share your ideas!
