Yea… so I was realllly bored today when I suddenly got into the mood for some Garrys Mod. Then I remembered the ridiculous wire mod addon (http://wiremod.com) that lets you wire electrical components together in the game. So one thing led to another, and eventually I made this 3-to-7 segment decoder. The 3 buttons on the wall represent 3 binary bits, and the display outputs the current binary number in a decimal format. So for example ‘011′ will output ‘3′ on the display. My digital circuits teacher would be proud.
