Make: brings us an article on another homemade computer , this one built almost entirely from transistors. Three thousand surface-mount BC847/BC857 low frequency transistors make up the registers, arithmetic logic, and other units that are typically integrated into the microprocessor in today’s computers. The MT15 runs at 500 kilohertz and has 128k of RAM, which is not transistorized.
This shows that "because I can," is often reason enough.
Meanwhile, Slashdot reports on the Open Prosthetics Project , a collaborative endeavor in which the share-and-share-alike Open Source philosophy is applied to prosthetics. I’ll be watching this project with interest to find out how quickly it can get from peg-leg to cyberpunk .
