OBD II to RS232 Convertor

[shaka_sam]

Does any one has any idea to make one?
ELM ICs can do this but I want to make it with either microcontroller or some other cheaper and easily available way.

Thanks!

Thanks for the reply, but I asked that I want to make one not buy one, andywhittaker is selling not giving me the schematic or anything.

If you could help me in that respect, I would be grateful.
Thanks again, I appreciate you interest.

First of all I am thankful for the reply you made. I knew that site but the problem was that I couldn't open the link, but now I can. Thanks again.
I might have some questions about the working but after I check the schematic, I am sure you would help me.
Thanks Again!
