Bush wants yet another $50 billion with another $150 billion to come for a failed and phoney war. Hello! This failure is coming in at well over $1.0 trillion. $200,000 spent on behalf of every Iraqi family for freedom. I support freedom, right here in the US. Another $200 billion while we spend a paltry $6 billion for cancer research. Hello, hello, hello!

With the dollar falling like a stone, a failing economy, failng US bridges, failing US levees, unable to even fund health insurance for US children, enough is enough. Congress. In case you didn't notice, the President isn't quite right. Its time to lead. No more for Iraq!

the Arduino. My current focus.

Use of a PC Printer Port for Control and Data Acquisition - Volume 2

Volume 2 is a follow on effort by undergraduate electrical engineering students Towanda Malone, Christine Samuels and Paul Roach and myself. This became known as the Rochanda Project, where Rochanda is a concatenation of Roach, Christine and Towanda. As you might guess, the name Rochanda was Towanda's idea!
