Making your own 4 bit computer from transistors

http://www.waitingforfriday.com/index.php/4-Bit_Computer

This video explains the theory behind how computers count and shows, in simple steps, how you can build your own 4-bit computer using logic gates which are made of individual transistors. The final result is a 4-bit adding computer which is capable of adding together two numbers and showing the result.\n\nIf you've ever been curious about how computers really work, or you're interested in logic circuits, this video is for you.
