I PMed him a little bit, this is what he said:


All your questions are in my organized notes and data in pdf. Many times I have ordered parts from radio shack even. Some parts are cents some are under $10, first prototype was not pretty due to trial and errors. You will need EE software to test design as well as ohm meter, micro solder kit, ect. Software wise gotta be decent at linux redhat . I did keep notes as I went along for my future replications, never thought I would share it one day. Please post in the forum due to many emails asking same questions, It would streamline information.
