Modern Processors are built using millions upon millions of transistors on tiny silicon chips. British man, James Newman decided that he wanted to know how they worked, up close and personal. Realising he would never be able to shrink down and walk around a silicon chip, he decided to scale up the computer instead.
The resulting project is called the Megaprocessor, a 40,000 discrete transistor, 10,000 LED, hand soldered computer. It fills a room, took him 1 year and around $70,000 AUD to build. This thing is impressive to say the least.

If that wasn't impressive enough, James' new mission is to create a series of videos on YouTube that go into explaining the finer points of CPU functionality. See those videos here
