I am glad that we have some EE minds on sajha board. EE folks, please don't mind if I shoot out emails asking you questions about quasistatic diffusion, delta-sigma A/D converter, carbon nanotubes or pentacene transistors. Embedded programming is my new found interest whereas mixed-signal VLSI design and digital control are the courses I am taking in college. ya all have a nice friday and a good weekend. P.S.: I admire the work done by Nikola Tesla whose works have been forgotten and largely uncredited. For those who are interested in Tesla's biography here is a good link http://www.pbs.org/tesla/index.html
