Dude, actually to my knowledge, i donno sites that offer tutorial for those projects. Personally, I've done the vehicle security, the password using MEMS and the DCS. As for software, you wont find complete tutorials (although you find it very rarely). You must analyse the blocks and study them seperately over net and then assemble them. Thats how this works as far as hardware projects are concerned (atleast as of now ).
And sorry, I was busy so cant reply
